cucumber step definitions best practices

This image by Cucumber reflects the idea of combining automated tests, having a living documentation, and at the same time, still having specifications that are executable. In this tutorial we’ll implement a basic scenario and look at the best practices that help writing maintainable tests. that you have read and agree to our Privacy Policy and Terms of Service. Instead of traditional callbacks we can either return a promise or use the done callback in our step definitions. On certain occasions, it may happen that we don’t want to execute all the scenarios of our test, but rather group certain scenarios and execute them separately. We use --require ./features/step-definitions/index.ts to import our Cucumber step definitions (Given, When, and Then). Write the scenarios as we would like them to be presented to us. 7,784 1 1 gold badge 10 10 silver badges 33 33 bronze badges. 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. It’s not necessary to define a head, although it is useful and advisable to be able to reference the data more easily. They are composed of a regular expression and a piece of code. A set of roles? Reuse step definitions as much as possible to improve code maintainability. Using soft assertions across multiple steps is not a best practice. Scenarios are simply the behavior of a functionality. 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. This topic describes best practices for writing BDD scenarios in CucumberStudio. This is practical not only to save the amount of code that has to be written, it also contributes a lot to the maintainability of the tests since it will eventually be less the number of step definitions that we will have to modify in any case. 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. 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: public void verifyEnabledCard() throws Throwable {, // Write code here that turns the phrase above into concrete actions, @When(“^Enter the \”([0-9]+)\” of the card $”), public void enterPIN(int pin) throws Throwable {. If we have a Scenario outline under a tag, all the data examples that the scenario has will be executed under that tag. This serves as a series of steps that will be executed before all the scenarios of the feature. Given that the specific role or user for which the scenario is constructed is specified in the description, and the idea is to put oneself in the shoes of that user, the use of the first person can be a coherent form of writing. This becomes the responsibility of the implementation of the Gherkin sentences that we write in the scenarios (step definitions). RUN YOUR CUCUMBER SCRIPT ON SELENIUM GRID, At times it becomes very confusing as to what perspective should you write your scenarios in – first person or third person? By: Luis Zambra, Vicente Saettone, and Federico Toledo, Ph.D. For every cucumber project there is a single directory at the root of the project named "features". Save my name, email, and website in this browser for the next time I comment. Best practices for scenario writing. An administrator, a particular user? These are called “step definitions.” In the “features” folder, create a new “steps” folder. Step – 6: The features and the step definitions hierarchy is a bit different from other languages. Always remember that the order of your statements must follow Given-When-Then. Follow this guide to change it for your steps. Note that you only need to state what you want to do in the feature file and not how you want to do it. This enables the selective running of tests through the cucumber … What is Automated Visual Regression Testing and Why Should You Invest in It? It follows a step and is enclosed within three double-quotes. Organize your features in separate folders. These are called “step definitions.” In the “features” folder, create a new “steps” folder. So far, we have only understood what our scenarios would do as part of Cucumber best practices. is a development strategy, and even if you do not follow this practice, we find it beneficial to use. In Ruby on Rails we keep our code DRY by sharing behavior by using inheritance, modules, traits or partials. Tags are simply the annotations used to group scenarios and features. 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. 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(); }. The important thing at this point, as already mentioned, is to maintain the consistency between the description of the scenario and its steps (not to alternate points of view), to respect the criteria used in the case that we are adding scenarios to an existing project and to favor clarity of what is written. The general syntax for writing a scenario in a feature file is-. It’s better to avoid writing scenarios in this way because it makes them very long, with many unnecessary details, so they are harder to read and understand. This means that anything ending in .java .kt .js .rb inside the directory in which Cucumber is run is treated as a step definition. Regards Sutiksha. Try writing brief sentences which are explanatory. It’s always better to have scenarios be as self-contained as possible, and in case you have a Background, make it as short as possible. They are marked with @ followed by some notable text. You benefit from reusing step definitions in the following ways: This makes it easy to maintain your tests when the tested app changes. The less you have to read to understand it, the better. 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. As an example, let us take the Login functionality using Gherkin. Try to define features logically and avoid having very large feature files containing many scenarios. While testing, we might have to write multiple scenarios to cover the test scope. Adding Step Definitions. We need to add some code. To begin, we create a folder in the project where we will save the features that we are going to write in Gherkin. The description should resonate with the test steps and be from a single perspective. Since the above steps would be common for many functionalities in a feature, we can include them in the Background. If the scenarios are interlinked, it may generate errors, for instance, in case of parallel test execution. A set of roles? It becomes crucial to bifurcate the feature in different files. Apart from the commonly used keywords discussed above, there are a few more that are used in Gherkin. In that folder, create a new file called “productSteps.js”. There may be reasons for conjunctive steps. Inside, you have different features like creating, editing, deleting and everything that has to do with them. These are some of the essential practices you should implement for successfully using Cucumber & Selenium. They are very practical because, thanks to this, it’s not necessary to write a scenario by input data. Are there any specific pre-requisites to be implemented while using glue option? To describe the scenarios, Gherkin sentences are used: Given, When, Then, But and And. Running Your First Test With NightWatchJS, Your email address will not be published. Scenario and Step Definition Best Practices - Cucumber Remove trailing white space before committing Trailing white space generates meaningless diff markers, making it harder to see the … Call other step definitions. Grunt integration. Having coupled scenarios can generate errors, for example, if we have to run them in parallel, or if one fails. 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. 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. However, this is not the complete job done. In a follow-up post I’ll provide some additional tips focusing on improving readability of website tests using the SAHI library of CWB. These acceptance criteria could be seen as the tests we are going to prepare. Step Definition (Implementation of the Steps). To describe the scenarios, Gherkin sentences are used: Given, When, Then, But and And. A Step Definition is a small piece of code with a pattern attached to it or in other words a Step Definition is a java method in a class with an annotation above it. We use cookies to ensure that we give you the best experience on our website. The above examples can be configured for execution as shown below-. The main difference between the two is that the Scenario outline injects the data at the scenario level, while the data table is used to inject data at the step level. When Cucumber executes a Step in a Scenario, it will look for a matching Step Definition to execute. To use them, you must add the desired text in the step between three quote marks (“””). For example: Scenario outline: … Given … When … Then I get money And the Confirmation message is displayed with the text:   “””   Dear Customer:   The following amount has been withdrawn from your account # : . 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). Cucumber varieties differ in the types of flowers they produce. He is also an experienced IT professional, who loves to share his thoughts about the latest tech trends as an enthusiast tech blogger. These practices can be applied to Cucumber scenarios in general. 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. If I write in a step “I delete an article from the system,” who is the one that is doing it? Last updated on November 23, 2020 . 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. An administrator, a particular user? The step definitions serve Cucumber as a translation of the steps we write in actions to execute to interact with the system. 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. Data Tables, in their structure and usefulness, are very similar to Scenario Outlines. 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. They are the representation of the specifications in code and instructions for cucumber on what to do. 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. jest-cucumber then allows you to link these Jest tests to your feature files and ensure that they always stay in sync. The ‘But’ statement works the same as ‘Then,’ but it is used when we want to verify that no concrete result is observed, for example: I should not be able to see this other result. 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. Suppose we are interested in modeling the behavior of an ATM when we want to withdraw money: 1. For example, let us name it “, Inside the file, we will give a title depicting the functionality. Scenario: As an existing user, I want to login successfully. To begin we create a folder in the project where we will save the features that we are going to write in Gherkin. In this directory you will find additional directories, which is step_definition and support directories What is "Feature File"? We have got our feature file ready with the test scenarios defined. Reuse step definitions. A better way to write the same scenario with fewer lines is as follows-, Did you see how with fewer sentences, we can depict the same scenario by including only the necessary details and ignore beating around the bush? To help you out, we will be diving into some of the best Cucumber practices that will enable you to write better scenarios using the Gherkin language. 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. The best part about using the Cucumber BDD framework are: Can’t wait to get started with Cucumber? , the use of the first person can be a coherent form of writing. The people who prefer the third-person point of view state that using first-person can confuse the reader. Step definitions are an important part of the BDD process with Cucumber. Cucumber Tutorial . 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. If you want to know more about this library, please refer to the introduction to WireMock. tags={“@SmokeTest” , “@RegressionTest”} In such definition, all the scenarios under the @SmokeTest AND @RegressionTest will be executed. Your email address will not be published. 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). 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. We need to add some code. 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. Below are the arguments for both the point of views-. Avoid coupled steps, i.e., always prefer creating one action per step. 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). Reusable step definitions will make your tests maintainable, and in case of any change in the future, you will have to make minimum changes to your framework. One way to reuse step definitions is to define them in Scenario outlines and parameterize them. When you reuse behavior you want to reuse tests as well. is a type of scenario where input data is specified. Cucumber doesn’t really know which piece of code is to be executed for any specific scenario outlined in a feature file. Step – 7: In this article we will use Swag Labs (https://saucedemo.com) website. … However, when an individual step completes, then it should give a clear result of PASS or FAIL. share | improve this answer | follow | answered Jan 11 '17 at 19:37. Cucumber needs Step Definitions to translate plain-text Gherkin Steps into actions that will interact with the system. 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]. The best way to make our Feature files understandable to a client is to use the same language that they use to describe the functionality, therefore, it is always better to describe the actions as the client would. It efficiently combines the automated tests having a living documentation and specifications that can be executed. We previously utilized the if/else statements with Ruby for Watir Webdriver scripts. It is advised that you make your feature file independent from other functionalities. 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 …”. For example, to order a product from an e-commerce website, you will have to do the following steps-. So lets understand more on Cucumber and Software development model it follows. 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. This is another one of the essential Cucumber best practices we recommend for seamless BDD implementation. text file where the acceptance criteria are written in Gherkin format. You can make your feature file understandable by using the same language as the requirement is specified, i.e., always try to describe the actions as they would have been done by the client. Cucumber starts it’s execution by reading the feature file steps. In a specific case, for an entertainment system, you might have this: In the first level we could have a folder, “Shows”. Try to make your scenarios independent. Over the course of time you will probably end up having many features and scenarios. Scenario outline: Withdraw money with different card keys. It helps in making the scenario understandable and clear. 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. Harshit works as a product growth specialist at LambdaTest. 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. In such cases, you can group specific scenarios and execute them independently by using Tags. Do you know Cucumber is a great tool used to run acceptance tests using the plain-text functional descriptions with Gherkin? For instance, we are resting the step definition for below step-. It's almost as if Cucumber is not loading the step definition files. Right now, i have lots of .feature files, and a single .cpp file containing step definitions. On the other hand, I find a lot of repeated step definitions (such as logging in) that end up being referenced in another file (unless I just want to change the wording intentionally). In this post, we’ll share some good Cucumber practices, especially when writing scenarios using the Gherkin language, clarifying some BDD concepts and from these practices, how to build better scenarios. How to organise step definitions. , Below are a few points that you need to keep in mind while writing scenarios in Gherkin-. There may be cases when you need not execute all the scenarios of the test. 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. Let’s see an example: Background: Given The credit card is enabled And The available balance in my account is positive And the ATM has enough money Scenario: …. BDD is somewhat similar to SBT (Sample Based Testing), in that it seeks to reduce ambiguities by showing examples. It also formalizes the Test-Driven Development best practices, in particular, the perspective of working from the outside-in. You will find many different ways to share code between Cucumber scenarios. 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. start build\examples\Calc\BoostCalculatorSteps.exe cucumber examples\Calc Getting started. Tests are first documented before being implemented. This is where all of your cucumber features will reside. 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. Cucumber is a testing framework which supports Behavior Driven Development (BDD). It is no compulsion to write a scenario with a scenario outline, but you can write it if needed. 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. Other Key Words to Describe the Scenarios. 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: …. Otherwise, a test report would show that step as passing with future steps … A Scenario outline is similar to the test data corresponding to a test scenario. When Cucumber matches a Step against a pattern in a Step Definition… Automatically when we do this, the step in the feature (the sentence in Gherkin) already recognizes where the implementation is. 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. The key with the Cucumber Feature file is, the shorter, the better. Here are the arguments in favor of each: Dan North (considered the creator of BDD), as we found in a reference in Stack Overflow, recommends the use of the first person, and in fact it’s what he uses to write his scenarios in his article, “Introducing BDD.” 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]”. 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. Its assertion results should not be punted forward to a future step or “after” hook. 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). 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. Try to write scenarios in the feature file in a way the user would describe them. We have already discussed these in a different article. Applies to CucumberStudio Cloud, and to Enterprise ver. tags={“@End2End”} All the scenarios of the feature under @End2End tag would be executed. This way it is better organized and easier to locate everything and each test. For example, if we are doing this at the level of the presentation layer, the Web GUI, then we are going to use something like Selenium, for which it would be good to follow some design pattern like Page Object. When Cucumber executes a step in a scenario, it will look for a matching step definition to execute. tags={“@SmokeTest , ~@RegressionTest”} All the scenarios under @SmokeTest tag will be executed but the scenarios under @RegressionTest tag would be ignored. … Let us now understand in detail some Cucumber best practices. 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. 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. It’s also argued that the use of the third person presents the information in a more formal and objective way. So writing a ‘When’ after ‘Then’, for example, would not be good conceptually and unclear. This is because every scenario depicts an individual functionality. Luis Zambra, Vicente Saettone, and Federico Toledo, Ph.D. The step definitions serve Cucumber as a translation of the steps we write in actions to execute to interact with the system. Step definitions should be very short because the bulk of automation work should be handled by support classes for maximum code reusability. 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). Luckily, Cucumber.js provides some helpful messages. The defenders of this position argue that the use of the first person makes the scenario reader lose reference to the role or the user that is being talked about. We will see the practical implementation later. 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]”. Having assigned our tags, there are many ways to configure them in the execution in the tag section of @CucumberOptions. We will start by creating a file in our project structure that will consist of the steps to mimic a certain functionality. How To Group Test Cases In TestNG [with Examples]. In addition, to make the article self-contained and independent of any external REST services, we will use WireMock, a stubbing and mocking web service library. Step timeout. 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. LT Browser – Our Desktop App for Fast & Easy Mobile View Debugging and Web Testing. 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? Try to leverage the use of Background to minimize unnecessary addition of the same steps in different scenarios. Be careful! Cucumber is a very powerful testing framework written in the Ruby programming language, which follows the BDD (behavior-driven development) methodology. Cucumber.js default step timeout is 5000ms. On selecting any of the options, a method will be created in the class. Folder Structure for BDD-Cypress. Doing so will make your project organized, and it will be easy for you to locate the tests as per the functionality. If one step needs to make a few assertions inside itself, that’s okay – soft assertions can be used internally. Call step definitions from other step definitions by calling steps helper. Adding Step Definitions. Inside, you have different features like creating, editing, deleting and everything that has to do with them. Make sure that your sentences are consistent when talking about perspective. Since step definitions is code, you should use static analysis tools routinely to check for standards downgrades. In that folder, create a new file called “productSteps.js”. To use them, you must add the desired text in the step between three quote marks (“””). 4. https://www.spritecloud.com/2018/03/the-3-most-common-mistakes-writing-gherkin-features/, https://automationpanda.com/2017/01/18/should-gherkin-steps-use-first-person-or-third-person, Webinar Summary: BDD and CD with Lisa Crispin. As soon as Cucumber reaches the first step for e.g. This means try to make each feature specific to a single functionality. Scenario Outline is a type of scenario where input data is specified. If we have a Scenario outline under a tag, all the data examples that the scenario has will be executed under that tag. In a specific case, for an entertainment system, you might have this: In the first level we could have a folder, “Shows”. Dan North (considered the creator of BDD), as we found in a reference in, , recommends the use of the first person, and in fact it’s what he uses to write his scenarios in his article, “.
