cucumber step definitions best practices

Always remember that the order of your statements must follow Given-When-Then. Automatically when we do this, the step in the feature (the sentence in Gherkin) already recognizes where the implementation is. jest-cucumber then allows you to link these Jest tests to your feature files and ensure that they always stay in sync. Are there any specific pre-requisites to be implemented while using glue option? This becomes the responsibility of the implementation of the Gherkin sentences that we write in the scenarios (step definitions). I've installed it and have some test scenarios and step definition files setup however when I run cucumber on my scenarios, each one comes up as undefined even though the step definition files have ruby code in them. They are composed of a regular expression and a piece of code. To make use of this feature, the functionality must be headed with “# language:”, followed by the dialect code to be used (for example, “# language: es”, for Spanish). In the same directory, Cucumber will search for a Feature corresponding to that step definition.This is either the default case or the location specified with therelevantrelevantrelevant-roption. Since in this post, we will understand Cucumber best practices, we will only focus on how we can write our features file to model our test scenarios. tags = {“@SmokeTest, @wip”} Execute all scenarios that are under the @SmokeTest tag or under the @wip tag (OR condition). Once you have completed the above steps, you can search the product, add that product to your cart, and proceed with the checkout and payment. You are probably already reusing examples in unit tests. Cucumber provides a way to configure this by means of tags. Step definitions should be very short because the bulk of automation work should be handled by support classes for maximum code reusability. Scenario and Step Definition Best Practices - Cucumber Published on March 6, 2017 March 6, 2017 • 23 Likes • 0 Comments 7,784 1 1 gold badge 10 10 silver badges 33 33 bronze badges. Cucumber is a buzz word these days. As an example, let us take the Login functionality using Gherkin. We will see the practical implementation later. When testing with live applications, you might have to create multiple feature files. [Cucumber CPP] Best practice for modularising step definitions Showing 1-2 of 2 messages [Cucumber CPP] Best practice for modularising step definitions: Jamie Bullock: 8/21/17 8:17 AM : This question relates specifically to cucumber-cpp. In this directory you will find additional directories, which is step_definition and support directories What is "Feature File"? For every cucumber project there is a single directory at the root of the project named "features". Having assigned our tags, there are many ways to configure them in the execution in the tag section of @CucumberOptions. Scenario Outline is a type of scenario where input data is specified. If you want to know more about this library, please refer to the introduction to WireMock. There are many different behavior-driven development approaches, but C u cumber and Gherkin have emerged as one of the most popular frameworks. Folder Structure for BDD-Cypress. Other Key Words to Describe the Scenarios. Inside, you have different features like creating, editing, deleting and everything that has to do with them. Cucumber offers the possibility of writing the scenarios in different human languages, following the same conventions that we normally use in English. A Step Definition is a small piece of code with a pattern attached to it. Luckily, Cucumber.js provides some helpful messages. Cucumber is a very powerful testing framework written in the Ruby programming language, which follows the BDD (behavior-driven development) methodology. A set of roles? On selecting any of the options, a method will be created in the class. Be careful! Tests are easy to understand for a user who doesn’t even know the functionality. To make use of this feature, the functionality must be headed with “# language:”, followed by the dialect code to be used (for example, “# language: es”, for Spanish). The available balance in my account is $10,000, I get $1,000 in the form of two $500 bills, The system displays the completed transaction message. 3) Handling Promises : Since cucumber.js is written using node.js, the step definitions are asynchronous. In Gherkin, scenarios are examples of individual behavior to establish acceptance criteria, so we may be interested in writing several by functionality to observe different results and make our test more complete (it’s recommended to write the positive scenarios first). Using Cucumber with outlined best practices in your automated tests ensures that your automation experience will be successful and that you’ll get the maximum return on investment (ROI). This topic describes best practices for writing BDD scenarios in CucumberStudio. Note that the tags are inherited in the feature file by all the components, viz the scenario outline, scenario, etc. tags={“@SmokeTest , ~@RegressionTest”} All the scenarios under @SmokeTest tag will be executed but the scenarios under @RegressionTest tag would be ignored. Writing Step definition … Otherwise cucumber doesn’t know when our asynchronous actions are complete. We need to add some code. This tended to make us have to re-word a lot of similar steps (like log-in) to avoid potential duplicate step definitions, which is easier to avoid and easier to maintain when all the steps are combined into one class. So, all in all, there is no mandate on using any one point of view; the one practice that you have to remember is to maintain consistency. For every cucumber project there is a single directory at the root of the project named "features". This way it is better organized and easier to locate everything and each test. Data Tables, in their structure and usefulness, are very similar to Scenario Outlines. … Best practices for scenario writing. When Cucumber runs a step in the Scenario, it refers to a matching Step Definition for execution. Cucumber is a testing framework which supports Behavior Driven Development (BDD). It follows a step and is enclosed within three double-quotes. A very common question that arises at the time of writing a scenario is the point of view that should be used. Doc Strings are useful to add strings of long characters to a step in a neater way. Choosing any of these two options will generate a method in the class, for example if we decide to create a step definition for the step: We will automatically generate a method with an annotation, where the header text will match the description of the step: @Given(“^The credit card is enabled$”)    public void verifyEnabledCard() throws Throwable {       // Write code here that turns the phrase above into concrete actions         throw new PendingException(); }. It is not necessary to use the Data Table in that way, but it is included as an example of how the input data can be used in a scenario. Given I authenticated with a card enabled And The available balance in my account is positive When I select the option to withdraw money And I enter the amount of money that is less than the amount I have available and the ATM’s available balance Then I get the money And The money I get is subtracted from the available balance of my account And The system returns the card automatically And The system displays the transaction completed message. Note that you only need to state what you want to do in the feature file and not how you want to do it. The tags are annotations that serve to group and organize scenarios and even features, these are written with the @ symbol followed by a significant text, examples: @gui Feature: … @SmokeTest @wip  Scenario: … @RegressionTest Scenario: …. Here are some important points about scenarios and steps in Gherkin: Given I meet a precondition When I execute an action Then I observe this result But I should not be able to see this other result. To summarize this blog post, we would recommend you to-. The step definitions file should be located inside a folder and the best practice is to have the folder name, feature file name and the step definitions file name as one and the same. Always remember that Given-Then-When should occur only once per scenario. To start writing step definitions, if we are working on an IDE with dependencies of Gherkin and Cucumber already installed, it will suggest us to implement them (they will appear underlined), and it will allow us to create a .java file or choose one where we already have steps implemented. Do you know Cucumber is a great tool used to run acceptance tests using the plain-text functional descriptions with Gherkin? What we did previously was the specification of the steps of our scenarios, we describe what processes our test will follow, but we do not define how we want it to be done. So far, we have only understood what our scenarios would do as part of Cucumber best practices. The description should resonate with the test steps and be from a single perspective. Some examples: In short, tags are not only useful for organizing and grouping our scenarios/features (which contributes a lot to the clarity of the test), but also allow us to execute them selectively, such as, for example, executing the fastest scenarios more frequently. For example, it’s not convenient if, in a scenario, we insert records in a database, the result of following scenarios depends on the existence of those records. These acceptance criteria could be seen as the tests we are going to prepare. As you can see in the previous example, a Doc String (which is in itself an input data) can be used in combination with other input data to show data specific to the scenario that is being executed. This becomes the responsibility of the implementation of the Gherkin sentences that we write in the scenarios (step definitions). Then, depending on what level we do the tests, other files may be needed. Here are some important points when implementing step definitions: The most advisable thing is to create step definitions that only have to be implemented once and reused in many scenarios (even of different features). As shown in the example above, you can use a data table at single steps with different data that you may need to inject. To use them, you must add the desired text in the step between three quote marks (“””). tags = {“[email protected]”} ignores all scenarios under the @SmokeTest tag tags = {“@RegressionTest, [email protected]”} executes all scenarios under the @RegressionTest tag, but ignores all scenarios under the @SmokeTest tag tags = {“@gui”, “[email protected]”, “[email protected]”} ignores all the scenarios under the tag @SmokeTest and @RegressionTest but executes all those under the tag “@gui”, if we follow the example it’s like running all the scenarios of the feature that are not under any other tag. tags={“@SmokeTest” , “@RegressionTest”} In such definition, all the scenarios under the @SmokeTest AND @RegressionTest will be executed. We have got our feature file ready with the test scenarios defined. Try to make your scenarios independent. The step definitions serve Cucumber as a translation of the steps we write in actions to execute to interact with the system. is a type of scenario where input data is specified. Quality Sense Podcast: Anand Bagmar – What You Should Know About Visual Testing, Quality Sense Podcast: Andreas “Andi” Grabner – Introduction to Keptn, Quality Sense Podcast: Ian Goddard – Testing Virtual Reality Software. Given The credit card is enabled And The available balance in my account is positive And the ATM has enough money When I put the card in the cashier And I enter the following and get the result : In the previous example, we added a second column “result”, to indicate the expected result according to the entered PIN (“1234” is incorrect and “9876” is correct). When Cucumber matches a Step against a pattern in a Step Definition… With this you need to make a note of the important points listed below-, Next, in the feature file, you will be writing the Scenarios. In the official Cucumber documentation, you can find all the necessary information to use this feature, including the code of each dialect and the words that should be used for each language to replace the typical ones. The examples used in the official documentation of Cucumber use both points of view, so it is not an exact reference to solve the problem. To work with Cucumber, you will need these files: To begin we create a folder in the project where we will save the features that we are going to write in Gherkin. However when I try to use glue option in Cucumber Options in my Runner class and try to execute the feature file as Cucumber feature, the step definitions are not invoked and the execution ends with scenario & step count and code snippet. https://automationpanda.com/2017/01/25/bdd-101-introducing-bdd/, https://hiptest.com/docs/writing-scenarios-with-gherkin-syntax/, https://docs.cucumber.io/gherkin/reference/, https://www.foreach.be/blog/9-tips-improving-cucumber-test-readability, https://saucelabs.com/blog/write-great-cucumber-tests, https://blog.codeship.com/cucumber-best-practices/, https://automationpanda.com/2018/02/03/are-gherkin-scenarios-with-multiple-when-then-pairs-okay/, https://automationpanda.com/2018/01/31/good-gherkin-scenario-titles/, https://automationpanda.com/2017/01/30/bdd-101-writing-good-gherkin/, http://toolsqa.com/cucumber/background-in-cucumber, https://www.engineyard.com/blog/15-expert-tips-for-using-cucumber, http://toolsqa.com/cucumber/cucumber-tags/. Given the statement of Scenario, it looks for the same statement in the Step Definition file, the moment it finds the statement, it executes the piece of code written inside the function. When Cucumber runs a step in the Scenario, it refers to a matching Step Definition for execution. Cucumber doesn’t really know which piece of code is to be executed for any specific scenario outlined in a feature file. tags={“@End2End”} All the scenarios of the feature under @End2End tag would be executed. There may be reasons for conjunctive steps. So lets understand more on Cucumber and Software development model it follows. Try writing brief sentences which are explanatory. Write the sentences to be explanatory and brief. We need to add some code. So in our example it can be something like “, We will now start writing our scenarios in the feature file. I enter the following and get the result : Cucumber offers the possibility of writing the scenarios in different human languages, following the same conventions that we normally use in English. In such cases, you can group specific scenarios and execute them independently by using Tags. The reason for this is that a scenario represents an individual behavior, and if we define something of the style: ‘Given-When-Then-When…,’ we can surely divide it into more than one scenario. Cucumber needs Step Definitions to translate plain-text Gherkin Steps into actions that will interact with the system. This means, if some common steps have to be executed for all the scenarios in a feature, you can write them under the Background keyword. Doing so will make your project organized, and it will be easy for you to locate the tests as per the functionality. It’s very important that the scenarios are as independent as possible, that is to say: scenarios can’t be coupled. Grunt integration. It is no compulsion to write a scenario with a scenario outline, but you can write it if needed. Nice introduction! Avoid coupled steps, i.e., always prefer creating one action per step. It's almost as if Cucumber is not loading the step definition files. LT Browser – Our Desktop App for Fast & Easy Mobile View Debugging and Web Testing. Its intent is to enable developers to write high-level use cases in plain text that can be verified by non-technical stakeholders, and turn them into executable tests, written in a language called Gherkin. Step timeout. If the scenarios are interlinked, it may generate errors, for instance, in case of parallel test execution. Scenarios can include steps that sound very similar or even the same, for instance, test scenarios for an online shop can contain a step like “Given the user is logged in …”. (Avoid) Use many_steps helper. But you could end up fighting the test framework a little, or going against your rationale for using Cucumber in the first place. To extend any of the sentences, ‘And’ is used. The official Cucumber BDD framework documentation uses both the point of view. To write a scenario, we use Keywords defined by Gherkin. Scenario outline: Withdraw money with different card keys. For example: the Confirmation message is displayed with the text: The following amount has been withdrawn from your account # : . But this is something more specific and dependent on what we are testing and in this post, we want to focus on Cucumber itself. They are marked with @ followed by some notable text. Apart from the commonly used keywords discussed above, there are a few more that are used in Gherkin. start build\examples\Calc\BoostCalculatorSteps.exe cucumber examples\Calc Getting started. The use of the first person allows writing the scenario to be coherent with its description, which, as mentioned above, usually follows the form “As [concrete user] I want [to perform concrete action] for [result or benefit]”. tags={~“@End2End”} All the scenarios under @End2End tag will be ignored. To work with Cucumber, you would need three types of files as described below: In the next section of this blog, we will understand feature files in detail and how we can use them efficiently. Always remember the below points while implementing step definitions-, You are now familiar with some of the most important Cucumber best practices to follow with your BDD strategy or while implementing Cucumber & Selenium. Simple best practices like the ones presented in this post can go a long way there. //Java code to check the above description. It’s fundamental that these tests be made clear to a user who does not know the behavior of the described functionality and that they be maintainable to reduce the costs of making changes in the test steps. This means try to make each feature specific to a single functionality. The most important thing is that the steps briefly describe what you want to do in the functionality and not how you want to do it (this is the responsibility of the step definitions, explained below). To begin we create a folder in the project where we will save the features that we are going to write in Gherkin. It is not necessary to define the head of a data table, but it is advised to maintain a reference to data for easy understanding. (or a similar tool) since it “forces you” to document your automated tests before implementing them. Right now, i have lots of .feature files, and a single .cpp file containing step definitions. When Cucumber executes a Step in a Scenario, it will look for a matching Step Definition to execute. To start writing step definitions, if we are working on an IDE with dependencies of Gherkin and Cucumber already installed, it will suggest us to implement them (they will appear underlined), and it will allow us to create a .java file or choose one where we already have steps implemented. If we have a Scenario outline under a tag, all the data examples that the scenario has will be executed under that tag. 4. All of this is thanks to the approach of using a tool like Cucumber. A Scenario outline is similar to the test data corresponding to a test scenario. Although the examples that will be given below for the implementation of the steps are developed in Java, it should be mentioned that Cucumber can also be used with JavaScript, Ruby, C ++ and other languages. Since the above steps would be common for many functionalities in a feature, we can include them in the Background. Its assertion results should not be punted forward to a future step or “after” hook. When separating the features, the amount of files can be enormous, so then you have to think about how to make the division of features in different files. Write Gherkin feature files and Java Selenium glue code to test web apps in behavior-driven development using Cucumber Rating: 4.2 out of 5 4.2 (434 ratings) 2,519 students The less you have to read to understand it, the better. Adding Step Definitions. A method would be generated automatically, with annotation having the header text same as that of the step description: To create step implementation of scenarios that get data from Scenario Outline or Data Tables, the data is included in the annotations as regular expressions, along with passing as a parameter to the method. Behavior Driven Development expands on Specification by Example. Having coupled scenarios can generate errors, for example, if we have to run them in parallel, or if one fails. It’s also argued that the use of the third person presents the information in a more formal and objective way. Similar to the examples above, you can make combinations of tags as per your requirement and execute the scenarios/features selectively. Cucumber is not limited to writing the scenarios in English. The step definitions file should be located inside a folder and the best practice is to have the folder name, feature file name and the step definitions file name as one and the same. In some way, the use of the third person diminishes the risk or the difficulty of the reader making erroneous assumptions about who is the stakeholder(s) involved. You can extend any sentence by using ‘And’. Here is a basic example on how to get started with cucumber-cpp. Given I authenticated with a card enabled And The available balance in my account is $10,000 And The cashier has $100,000 in cash When I select the option to extract money And I indicate that I want to extract $1,000 Then I get $1,000 in the form of two $500 bills And The balance of my account becomes $9,000 And the cashier keeps $99,000 in cash And The system returns the card automatically And The system displays the completed transaction message. add a comment | 2. It is recommended that the Background be as short as possible in terms of the number of steps, because if it is very long, it can be difficult to understand the scenarios that follow. In the case that the step includes input data defined through Scenario Outline or Data Tables, these data are included in the annotation as regular expressions, and in the method as received parameters: @When(“^Enter the \”([0-9]+)\” of the card $”)    public void enterPIN(int pin) throws Throwable {      // Write code here that turns the phrase above into concrete actions       throw new PendingException(); }. Required fields are marked *. Call step definitions from other step definitions by calling steps helper. In this directory you will find additional directories, which is step_definition and support directories What is "Feature File"? These are called “step definitions.” In the “features” folder, create a new “steps” folder. He is also an experienced IT professional, who loves to share his thoughts about the latest tech trends as an enthusiast tech blogger. Best practices for scenario writing. Always try to keep the background as short as possible since it will be difficult to understand the following scenario if it is kept lengthy. The primary keywords used in Gherkin sentences are –. Considering behaviours for Gmail sign in as a case study, paste the following cucumber scenarios into the app.feature file You will also get a clearer picture of the Behavior Driven Development concepts with these practices. There is no general rule about the point of view to use to write the scenarios. Automatically when we do this, the step in the feature (the sentence in Gherkin) already recognizes where the implementation is. For example, consider an e-commerce application – you can organize the file such that, at the first level, you can have a package, say Orders, and in that, you can have multiple features like Pending Orders, Completed Orders, Wishlist, etc. We leave you some references in case you want to continue reading about BDD, good Cucumber practices, or Gherkin: Webinar Summary: BDD and CD with Lisa Crispin When to Automate a Test? And that is how you can implement the steps that you write in the Feature file using Gherkin. Over the course of time you will probably end up having many features and scenarios. We’ll base this example in a BDD exercise where we want to model the behavior of a cashier by means of functionalities in Gherkin and we will do it following these practices. An administrator, a particular user? This tutorial gives an introduction to Cucumber, a commonly used tool for user acceptance testing, and how to use it in REST API tests. Cucumber is a tool that supports Executable specifications, Test automation, and Living documentation. These are some of the essential practices you should implement for successfully using Cucumber & Selenium. The examples used in the official documentation of Cucumber use both points of view, so it is not an exact reference to solve the problem. All of this is thanks to the approach of using a tool like Cucumber. This is another one of the essential Cucumber best practices we recommend for seamless BDD implementation. One way to start writing the feature can be this: Scenario: As an existing and enabled ATM user, I want to make a withdrawal to get money. It does not clarify who is performing the action, i.e., an individual user, an admin, or some user with a particular set of roles. Otherwise, a test report would show that step as passing with future steps … A popular option is to have a file with the features that group everything related to one aspect of the application and even organize them in directories. The important thing is to explain briefly what you want to achieve with the scenario. However, most of the time it’s best to avoid them. In a specific case, for an entertainment system, you might have this: In the first level we could have a folder, “Shows”. 3.3. For example, let us name it “, Inside the file, we will give a title depicting the functionality. For example, “Feature: Withdrawal of money”, We begin to write scenarios for our functionality. In this tutorial we’ll implement a basic scenario and look at the best practices that help writing maintainable tests. Step definitions are an important part of the BDD process with Cucumber. Try to write minimum steps in a scenario. See below an example of a poorly written scenario-, There is no point in writing such lengthy scenarios with unwanted details as it makes it difficult to read and maintain. Suppose we are interested in modeling the behavior of an ATM when we want to withdraw money: Inside the folder, we create a file with a .feature extension (for example “withdraw-money.feature”), We define a title that says what the functionality is. As much as possible, do not use many steps for a single scenario, the idea is that a user who does not know the functionality should be able to understand it by reading the scenario. What we did previously was the specification of the steps of our scenarios, we describe what processes our test will follow, but we do not define how we want it to be done. If in all the scenarios of the same feature, some preconditions are met, it is much more practical to use a Background than to write the same thing several times. tags={“@SmokeTest”} All the scenarios under @SmokeTest would be executed. Suppose we are interested in modeling the behavior of an ATM when we want to withdraw money: The description of a scenario is usually written as follows: Scenario: As [concrete user]           I want [take a concrete action]           for [result or benefit]. You can also use Grunt task runner to run the tests. In a follow-up post I’ll provide some additional tips focusing on improving readability of website tests using the SAHI library of CWB. However, when an individual step completes, then it should give a clear result of PASS or FAIL. Their two main differences are: Scenario: Withdraw money with different card keys. Scenario: As an existing user, I want to login successfully. Applies to CucumberStudio Cloud, and to Enterprise ver. This is where all of your cucumber features will reside. You might also like Getting Started With BDD In Behave Using Python, If you are using an IDE that already has Gherkin and Cucumber installed, you will see suggestions to create a new .java file or select one which has the steps implemented already. But the next and vital step to automate using Cucumber Selenium is adding Step Definition that would do the how part, i.e., how would the scenario execute. Is there something i am missing. Some varieties are gynoecious, producing only female flowers. Here’s a better and clearer way to write the scenario: Scenario: As an existing and enabled ATM user, I want to make a withdrawal to get money. Reuse step definitions as much as possible to improve code maintainability. To describe the scenarios, Gherkin sentences are used: Given, When, Then, But and And. As for a convention, I am not aware of enough REST API tests in practice to comment, and none that I have seen tested have used Cucumber as the framework. BDD is somewhat similar to SBT (Sample Based Testing), in that it seeks to reduce ambiguities by showing examples. The available balance in my account is positive, enter the amount of money that is less than the amount I have available and the ATM’s available balance, The money I get is subtracted from the available balance of my account, The system returns the card automatically, The system displays the transaction completed message. The general syntax for writing a scenario in a feature file is-. It is important to note that the tags that we specify to the titles of the Feature files will be inherited by the scenarios of the same, including Scenario Outlines.
