What's this?

grails-cucumber is a Grails plugin for Cucumber based on Cucumber-JVM.

Goals

• integrate cucumber (via cucumber-jvm) into the grails test runner as a grails test type "cucumber" to run cucumber scenarios via grails test-app and use Geb to implement cucumber steps definitions

Current State

It is not yet production ready... it is still a bit experimental but it is basically working. You can run cucumber scenarios with the steps implemented in geb and you can use grails domain classes in the steps as well. Take a look at the geb demo application in tests/projects/geb.

Cucumber-JVM is still a moving target, i.e. its api is still changing and it might brake the plugin code when you are using the master branch code.

• cucumber is implemented as grails test type that gets added to the functional test phase, e.g. to run the cucumber tests only use

grails test-app functional:cucumber

• you can run cucumber features with steps implemented using geb.
• cucumber features are expected in the test/cucumber folder using the typical cucumber layout.

  test/cucumber/step_definitions/XxSteps.groovy
  test/cucumber/step_definitions/YySteps.groovy
  test/cucumber/step_definitions/...
  test/cucumber/support/env.groovy
  test/cucumber/support/...
  test/cucumber/Xx.feature
  test/cucumber/Yy.feature

• place geb modules and pages in the usual place as well:

  functional/modules/XRowModule.groovy
  functional/modules/...
  functional/pages/XxPage.groovy
  functional/pages/YyPage.groovy

• see the sample project in tests/projects/geb for a full example grails project
• the plugin integrates into grails usual test reporting. So failing steps, steps with errors or undefined steps are all reported by grails as FAILED. The normal cucumber output can be found in target/test-reports

Todo

• keep up with api changes in cucumber-jvm
• the test report summary prints "Testcase: unknown took 0.065 sec", I do not yet understand why it prints "unknown" instead of the scenario name
• use grails like configuration for tags, language
• extend example

Source Notes

• the plugin has a number of unit tests and a single "cli" test. There are also a number of cucumber tests which are not meant to be run directly. They are only used by the "cli" test. You can run the cli test with

grails test-app other:cli

and the unit tests with

grails test-app unit:
