Running a Cucumber Feature File in Eclipse

I was tasked to improve an automation test that the offshore QA team has written for our web application.
I specifically have to update this Cucumber feature file.

Feature: Verify Search functionality

   Scenario: As a default User, I should be able to see search in Account page
      Given I do a default login
      When I view "Account" tab in Home Page
      Then I verify search ui functionalities

To a more granular test that when a default user do a search and the web application's dependent web service is down, then an error message will be displayed.

  • I am a Java developer but I have no background on QA testing nor Behavioral Driven Development (BDD), Cucumber, Selenium and all these tools that the offshore team has been using in their automation tests.
  • The QA Team has very little onboarding documentation so working on a Cucumber Feature file could be tricky.
  • We have an onshore QA Manager but he has got loads on his plate at the moment.
  • I was told not to run random tests off the project because it could cause issues in the Production environment.

To accomplish my almost impossible task, here are the steps I did.
  1. Import the project from Github into an Eclipse workspace.
  2. Install Cucumber Plug-in in Eclipse At this point, when I open the Feature file, I can see the file icon changed and the file text is color-coded.
  3. I try to run the feature file by right-clicking on the file.  Run As -> Cucumber Feature.  I got an error as below:
  4. This is because the Cucumber Eclipse plugin does not have Cucumber JVM and other JAR files needed to execute feature file.  Right-click on the project.  Select Properties -> Java Build Path -> Libraries.  Add External JARS. Then select the files that you must have previously downloaded from Maven Repository:
    • cucumber-core-1.2.4.jar
    • cucumber-java-1.2.4.jar
    • cucumber-junit-1.2.4.jar
    • cucumber-jvm-deps-1.0.5.jar
    • cucumber-reporting-2.2.0.jar
    • gherkin-2.12.2.jar
    • junit-4.12.jar
    • mockito-all-2.0.2-beta.jar
    • selenium-java-2.41.0.jar
  5. I tried doing again step #3 but failed.  At this point, I found a blog post that made it work.  I created a Run Configuration.  From the menu, select Run -> Run Configuratons.. -> Cucumber Feature -> New.  Select the project you are in.  In the Arguments, enter 
    6. --glue AcceptanceTestCases src/Search.feature --format pretty
    VM arguments: 
    -ea
  6. Execute this configuration and the Feature file should run smoothly.
