Improve test run in hybris

OOTB hybris provides ant unittests command to run unit and integration tests, which are pretty low level and requires additional configuration to simplify run and result collection for DevOps. Below you can find configuration for buildcallbacks.xml, which you can just copy-paste into any hybris project (version 6.0+) and significantly simplify DevOps job required for setup of CI/CD pipeline.

First of all was added ant ci, ci-ut, ci-it, ci-reports targets. This commands are wrappers for ant unittests and ant integrationtests targets with such improvements:

  • Test runs with JaCoCo(code coverage utility)
  • ci-ut runs both regular and web unit tests
  • ci-ut runs unit tests without starting of hybris minimal-wrapper server
  • ci-it runs integration tests (web integration tests are not run)
  • ci-report combines reports of unittests and integration tests in one report
  • ci, ci-ut, ci-it targets creates junit reports in ${HYBRIS_LOG_DIR}/ci-ut, ${HYBRIS_LOG_DIR}/ci-it or ${HYBRIS_LOG_DIR}/ci directories. Inside this directories will be generated jacoco-report directory with report on coverage

Usage is same as ant unittests. It means that you are able to use “-D” properties to filter tests, for example ant ci -Dtestclasses.extensions=trainingcore.

Was introduced new run attribute -Dtestclasses.all.custom.extensions=true for ant ci, ci-ut, ci-it, ci-reports targets, which will execute tests inside all custom extensions, so there is no more need into manual scan of extensions and usage of -Dtestclasses.extensions=.

For jacoco coverage reports you must add jacoco agent with all dependencies into your classpath. For example, you can add jacoco into your external-dependencies.xml and use ant updateMavenDependencies command to download dependencies.
