Global BeforeAll Hook for cucumber-jvm?

Question

The ruby version of cucumber supports a global before hook. An *.rb file placed in the features/support directory gets apparently called only once, before any and all scenarios run. See https://github.com/cucumber/cucumber/wiki/Hooks#global-hooks

That seems to be a great way to make sure a database (used in read-only during tests) gets populated (and thus is in a known state) before any tests run.

Is there a similar feature available for the Java version of cucumber?

Answer 1

There is no such feature natively in Cucumber JVM (see https://github.com/cucumber/cucumber-jvm/issues/515).

However, there are a couple of workarounds:

• Use the hooks of your test framework:
  • @BeforeAll and @AfterAll for JUnit 5,
  • @BeforeClass and @AfterClass for JUnit 4
• Use a Cucumber Before hook for lazy singleton initialization and a JVM shutdown hook for teardown
• Implement a Cucumber EventListener and subscribe to TestRunStarted and TestRunFinished events
• Use the integration test lifecycle features of your build framework, e.g. Maven's pre-integration-test, integration-test, post-integration-test phases and the maven-failsafe-plugin.

You will also have to solve the issue of injecting the results of such a setup step (e.g. random port numbers) into your tests.

I wrote a blog article to cover all details: https://metamorphant.de/blog/posts/2020-03-10-beforeall-afterall-cucumber-jvm-junit/
