Cucumber is a tool that supports Behaviour-Driven Development (BDD) - a software development process that aims to enhance software quality and reduce maintenance costs. On the other hand, TestNG is detailed as "A testing framework inspired from JUnit and NUnit".
In the above code we run the cucumber test by using the following annotations: @RunWith() annotation tells about the test runner class to start executing our tests. @CucmberOptions() annotation is used to set some properties for our cucumber test like feature file, step definition, etc.
These stages and principles are summarised here:
- All tests are written before the code.
- Write a test.
- Run all tests to check that the new test fails.
- Write the code.
- Re-run the tests.
- Refactor the code if necessary.
- Re-run the tests.
Following is the step-by-step process of how Cucumber works with Ruby.
- Step 1 − Install Ruby.
- Step 2 − Download and extract Dev kit.
- Step 3 − Install Cucumber and other Ruby gem.
- Step 4 − Install IDE – KOMODO.
- Step 5 − Install Watir − Go to command prompt and run the following command, "gem install watir"
Restart Jenkins after this plugin is installed.
- Reconfigure the Jenkins task. The Cucumber reports plugin generates reports by parsing the json report file that Cucumber or CukeTest create.
- Display [Cucumber reports] In the [Add post-build operation steps] select the [Cucumber reports] option.
- Generate test report.
A cucumber is a tool based on Behavior Driven Development (BDD) framework which is used to write acceptance tests for the web application. It allows automation of functional validation in easily readable and understandable format (like plain English) to Business Analysts, Developers, Testers, etc.
The best option appears to be one TestNG test runner per feature file. You can use Cucumber with either JUnit or TestNG, if you want to run it from a test framework. You can also run it directly from the command line, from your IDE or from a build tool like Maven or Gradle.
Running Gherkin Tests in the Suite Window
Running a Gherkin test in the Eggplant Functional Suite window is similar to running scripts. With the test you want to run selected in the editor, you can: Click the Run Script button. Select lines in the Feature, then click Run Selection to run only the selected lines.By default, the main class name is cucumber. cli.
To enable Cucumber support via libraries, follow these general steps?
- In a project where Cucumber tests should be created, click. . Project Structure dialog box opens.
- In the Modules page, click Dependencies tab, and add the required Maven dependencies: Click.
- Apply changes and close the Project Structure dialog box.
Running Cucumber with Serenity feature files directly from
- Click on the feature file you want to run.
- In the Run menu Select Run
- In the contextual menu, select the feature, then "Edit"
- You should now see the 'Edit Configuration Settings' window. Set the main class to 'net.
- Change the Glue field to the root package of your project (or of your step definitions)
- Click Apply.
In order to
execute Cucumber test with
command prompt, use the following steps after system configuration. Step 1− Create a Maven Test Project named
commandLine.
Result
- Now run command mvn test - Dcucumber.
- To run the specific tags only, run the command mvn test -Dcucumber.
To run Cucumber test with Java, following are the steps.
- Install Eclipse IDE -Make sure java should already be installed on your machine.
- Then Create the New Project in Eclipse IDE by following steps:
- Then Configure Cucumber with Maven.
- Once pom.xml is edited successfully, save it.
Here's how:
- Click on the feature file you want to run.
- In the Run menu Select Run
- In the contextual menu, select the feature, then "Edit"
- You should now see the 'Edit Configuration Settings' window.
- Change the Glue field to the root package of your project (or of your step definitions)
- Click Apply.
In order to debug your scenarios on the JVM, you can step through the the steps of each scenario in debug mode.
- Set a breakpoint on the part of the code you want to debug.
- Run your RunCucumberTest in debug mode.
- The execution will stop at your breakpoint.
- Now you can either:
- And so on..

- Launch Eclipse and navigate to 'Help->Install New Software'.
- Click on 'Add' button.
- Click on OK.
- 'Cucumber Eclipse Plugin' option will appear in the available software list.
- Select the check box against it and click on 'Next' button.
Creating step definition?
- While editing the .feature file, type a reference to a step definition.
- Press Alt+Enter to show the Create Step Definition intention action:
- Select the target step definition file from the list:
- In the selected step definition file that opens in the editor, enter the desired code.
An annotation followed by the pattern is used to link the Step Definition to all the matching Steps, and the code is what Cucumber will execute when it sees a Gherkin Step. Cucumber finds the Step Definition file with the help of the Glue code in Cucumber Options.
To do so:
- Open your feature file.
- Right-click in the editor and select Generate Step Definitions from the menu.
- A dialog is displayed with a list of the steps in your feature file.
- Enter a name for your class in the Class name field.

To create a feature file?
- In the Project tool window, right-click a directory, where feature files should be created.
- From the context menu of the target directory, choose New | File, and in the New File dialog, type <name>. feature .
- In the feature file, type your scenario.
- Create step definitions.
