When creating a bug report for any project within the Hibernate family, it’s extremely helpful (and, frankly, required) to have an adequate test case available. This is obviously important to make reproducing the issue as easy as possible. But it’s also vital longer-term. Nearly every bug fix should include a regression test, which is frequently based on the original reproducer (sometimes, it’s the reproducer, verbatim).
To help create useful test cases, we’re opening up a repo with various templates. Please see the READMEs in each project’s subdir for more info: Hibernate Test Case Templates
As a starting point, the repo contains two templates for ORM:
ORMUnitTestCase: By far, this one’s the most helpful. ORM includes a built-in unit test framework that does much of the heavy lifting for you. All that’s required is your entities, logic, and any necessary settings. Since we nearly always include a regression test with bug fixes, providing your reproducer using this method simplifies the process. We can then directly commit it, without having to mold it in first. What’s even better? Fork hibernate-orm itself, add your test case directly to a module’s unit tests (using the template class), then submit it as a PR!
ORMStandaloneTestCase: This template is standalone and will look familiar. It simply uses a run-of-the-mill ORM setup. Although it’s perfectly acceptable as a reproducer, lean towards
The eventual goal is to also include templates for Validator, Search, and OGM.
As always, this is open source for a reason! If the templates can be improved in any way, please let us know (either through our JIRA instance or through GitHub Issues). Better yet, send us a pull request!
