cucumber feature file best practices

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. 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. Try writing brief sentences which are explanatory. Before we jump dive into Cucumber best practices, there are a few things you need to understand about the Cucumber BDD framework. Nobody wants a thousand-line feature file. The official Cucumber documentation has all the information about using the Language feature and the dialect code of various languages. Considering this, perhaps the previous example would be better if we lower it to specific data, as in the following case:Scenario: As an existing and enabled ATM user, I want to make an extraction to get money.Given I authenticated with a card enabledAnd The available balance in my account is $10,000And The cashier has $100,000 in cashWhen I select the option to extract moneyAnd I indicate that I want to extract $1,000Then I get $1,000 in the form of two $500 billsAnd The balance of my account becomes $9,000And the cashier keeps $99,000 in cashAnd The system returns the card automaticallyAnd The system displays the completed transaction message. 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. Cucumber is not limited to writing the scenarios in English. While testing, we might have to write multiple scenarios to cover the test scope. The general syntax for writing a scenario in a feature file is-. The most advisable thing is to use one feature per system functionality, making sure the Feature is specific to a single functionality in particular and is as independent as possible from other functionalities. Some examples: tags = {"@SmokeTest"} Execute all scenarios under the @SmokeTest tag. 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. A feature file can contain a scenario or can contain many scenarios in a single feature file but it usually contains a list of scenarios. These are some of the essential practices you should implement for successfully using Cucumber & Selenium. Avoid coupled steps, i.e., always prefer creating one action per step. Join the DZone community and get the full member experience. 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. https://stackoverflow.com/questions/34839651/what-person-and-mood-should-i-use-in-gherkin-specflow-given-when-then-statements. Let’s review some important best practices needed before you start developing Cucumber tests. 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). Tag starts with “@”. Having assigned our tags, there are many ways to configure them in the execution in the tag section of @CucumberOptions. Scenarios are simply the behavior of a functionality. So basically, a Feature File is a file in which the Cucumber tests are written. Diameter, RADIUS, SOAP, REST, SMPP, SMTP, SCTP etc . Use the process part two that we discussed. Since the above steps would be common for many functionalities in a feature, we can include them in the Background. """. Their two main differences are: Scenario: 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 cashierAnd 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). 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. Let’s create one such file.
