testing - Execute some action when Spock test fails

Question

I'd like to execute some action when Spock test fails. Specifically, take a screenshot. Is it possible? How to do it?

Answer 1

Create a listener class

class ExampleListener extends AbstractRunListener {

  def void error(ErrorInfo error) {
    println "Actual on error logic"
  }
}

then add it to each specification using implementation of IGlobalExtension that is executed for each Spec

class GlobalSpecExtension implements IGlobalExtension {

  @Override
  void visitSpec(SpecInfo specInfo) {
    specInfo.addListener(new ExampleListener())
  }
}

and finally create file named org.spockframework.runtime.extension.IGlobalExtension in your META-INF/services directory (typically it will be under src/test/resources if you are using Maven) with the full name of your IGlobalExtension implementation e.g.

com.example.tests.GlobalSpecExtension
