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. For example, "Feature: Withdrawal of money", We begin to write scenarios for our functionality. //Java code to check the above description. In a specific case, for an entertainment system, you might have this: In the first level we could have a folder, "Shows." tags={“@SmokeTest , @RegressionTest”} This type of definition denotes OR condition hence, all the scenarios that are under @SmokeTest tag or @RegressionTest tag would be executed. Use the optimal Cucumber automation process. 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. tags = {"@gui," "~@SmokeTest," "~@RegressionTest"} 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. The way you write your steps depends on how you want to use your cucumber suite. The suggested best practice is, to write down a small description of the function beneath the feature name in the feature file. BDD is a development strategy, and even if you do not follow this practice, we find it beneficial to use Cucumber (or a similar tool) since it "forces you" to document your automated tests before implementing them. 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. A Feature File can be interpreted to make the documentation more understandable. tags={“@SmokeTest” , “@RegressionTest”} In such definition, all the scenarios under the @SmokeTest AND @RegressionTest will be executed. Cucumber: It is used to describe the interpreter used to process Gherkin syntax. An example of a badly written scenario is this: Given I authenticated myself with an enabled cardAnd The available balance in my account is positiveAnd the ATM has enough moneyAnd the ATM has enough paper to print receiptsWhen I put the card in the ATMAnd I input into the keyboard my card’s pinAnd I press the confirm pin buttonAnd I press the button next to the option to withdraw moneyAnd I enter an amount less than or equal to my available balanceAnd I press the button to confirm the withdrawalAnd I press the button to print the receipt. 2. Make sure that your sentences are consistent when talking about perspective. 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. 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. A file that saves data about features, their explanations, and the scenarios to be tested, is named a Feature File. In such cases, you can group specific scenarios and execute them independently by using Tags. This is another one of the essential Cucumber best practices we recommend for seamless BDD implementation. It’s also argued that the use of the third person presents the information in a more formal and objective way. 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. A Scenario outline is similar to the test data corresponding to a test scenario. Try to make your scenarios independent. You’ll get the most benefit out of using Cucumber when your customers are involved. This will fulfill the need of a good documentation as well. 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. Try to write minimum steps in a scenario. Scenario outline: Withdraw money with different card keys.Given The credit card is enabledAnd The available balance in my account is positiveAnd the ATM has enough moneyWhen I put the card in the ATM. Suppose we are interested in modeling the behavior of an ATM when we want to withdraw money: 1. 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). Before we jump dive into Cucumber best practices, there are a few things you need to understand about the Cucumber BDD framework. They are marked with @ followed by some notable text. 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. 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. The above examples can be configured for execution as shown below-. As a beginner, I broke many of the guidelines I put in this post, but I learned as I went. A … Or rather, we can say that it's a file in which we write the Scenarios for our acceptance tests. Adding Test case To Cucumber Feature File On selecting any of the options, a method will be created in the class. These are some of the essential practices you should implement for successfully using Cucumber & Selenium. For instance, we are resting the step definition for below step-. 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. Now we go to the file … The feature file is an entry point, to write the cucumber tests and used as a live document at the time of testing. 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. 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. We use cookies to ensure that we give you the best experience on our website. ... Best practices to write feature file. He is also an experienced IT professional, who loves to share his thoughts about the latest tech trends as an enthusiast tech blogger. If we have a Scenario outline under a tag, all the data examples that the scenario has will be executed under that tag. There is no general rule about the point of view to use to write the scenarios. Using the first person is rational since it depicts keeping yourself in place of the person actually performing the action. Note that you only need to state what you want to do in the feature file and not how you want to do it. Cucumber Ruby creates a `/features` directory by default to house `.feature` files. With these best practices, you can write Gherkin feature files like a pro. Data Tables, in their structure and usefulness, are very similar to Scenario Outlines. Below are the arguments for both the point of views-. The key with the Cucumber Feature file is, the shorter, the better. 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. Though often overlooked, it is one of the most crucial Cucumber best practices to follow. 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, Developer # Example of Best Practices for Gherkin Syntax. 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. Compose all steps in third-person perspective.On the off chance that first-person & third-person advances blend and situations wind up confusing, simply utilize third-person at all times. Nobody wants a thousand-line feature file.
