Different ways to hook into the JVM cucumber lifecycle

Cucumber lifecycle demo

This repo contains the examples for the blog article about Getting @BeforeAll and @AfterAll behaviour with Cucumber JVM and JUnit. It contains a little set of demos showing how you can tap into the lifecycle of JVM cucumber to create the equivalent of a @BeforeAll/@AfterAll.

How to reproduce

Cucumber EventListener

cd cucumber-eventlistener-demo
mvn test

Please note the order of output: The lifecycle hooks' output is interleaved with the other Cucumber test output.

Cucumber Before and shutdown hook

cd cucumber-global-hook-demo
mvn test

The order of the output shows: The Before is called inside the Cucumber lifecycle, while the shutdown hook is called at JVM termination time -- just before Maven reports the test results.

JUnit Wrapper

cd junit-wrapper-demo
mvn test

Please note the order of output: The @BeforeClass/@AfterClass hooks' output is written before/after the whole Cucumber test and runner output. The @Before/@After hooks are never executed.

Maven Failsafe

Maven failsafe is bound to the integration-test phase resp. the verify phase instead of the test phase of the Maven build lifecycle.

cd maven-failsafe-demo
mvn verify

In the output you notice the additional echo of the port in the pre-integration-test phase. In this case, the port mappings are managed by maven and injected into the test as system properties from the outside.

This gives you less detailed control, but draws a clear boundary. Also, it enables you to run the test in the same fashion against different environments without having to change the code.
