While it's possible to configure these in your local environment via GRADLE_OPTS or JAVA_OPTS, it is useful to be able to store certain settings like JVM memory configuration and Java home location in version control so that an entire team can work with a consistent .

Another common step is to attach all the unit test dependencies to the integration tests as well via intTestImplementation.extendsFrom testImplementation but that only makes sense if the integration tests require all or nearly all the same dependencies that the unit tests have. Find centralized, trusted content and collaborate around the technologies you use most. Always use the Gradle wrapper 2. However, as gradle distributes tasks to workers statistically (see here) there is a chance that all my integration tests get allocated to the same worker. Run tests in parallel 6.
