The one where scenario is run from feature file

Posted on November 7, 2016

In the following post I will share a quick tip on how to set up Idea to run scenario from feature file

Intellij IDEA 2016.2 CE is used as IDE

Target audience: QA Automation engineers / developers

DISCLAIMER: It is assumed that reader has some experience with Cucumber test tool and Cucumber for Java plugin is installed for Intellij Idea.

Problem: Why do we need configurations?

Cucumber features and separate tests can be run using custom runner classes. In this classes you can set up various configurations, such as: features and tags to run, output formatters, etc.

For example:

 package steps  

 import cucumber.api.CucumberOptions  
 import cucumber.api.junit.Cucumber  
 import org.junit.runner.RunWith  

 @RunWith(classOf[Cucumber])  
 @CucumberOptions(  
  features = Array("classpath:features"),  
  glue = Array("classpath:steps"),  
  tags = Array("@wip"),  
  monochrome = true,  
  plugin = Array("pretty",  
   "html:target/cucumber",  
   "json:target/cucumber/test-report.json",  
   "junit:target/cucumber/test-report.xml")  
 )  
 class TestRunner {}

But at some point you may want to have possibility to run feature or single scenario just within feature file.
And if you test project has a non trivial structure, Cucumber may not see package with Step Definitions - as a result scenario will not be executed and signals that step definitions were not found.

Below you will a find a tip on how to handle such situation.

Solution: How to set up default configuration for Cucumber?

Just follow the next steps:

  • Open Edit and Configurations window

Project Structure

  • Open list of default configurations

Project Structure

  • Find Cucumber for Java configuration
  • Set main class - e.g. cucumber.api.cli.Main
  • Fill glue section with name of package, where step definitions located
  • Set VM options and classpath if it is needed

Project Structure

  • Save default configuration
  • Run any scenario or feature just by right click on it’s name and select “Run scenario” or “Run feature”

NOTE: By default Cucumber will automatically generate program arguments and path to feature file each time, when you run any scenario or feature.

Conclusion

Default configuration can be very useful in day to day activities for running / debugging any single scenario or while refactoring step definition code.
