The commercial editions of jOOQ provide source code access. I've seen the "integration tests" mentioned a few times in the jOOQ-related documentation and community discussions. Never a link to them though. Are the integration test suites accessible to people buying commercial edition?
I believe having access to and run test cases would greatly help with understanding how to use jOOQ topics in which documentation is not enough for me to understand specific features.
I searched the source code of the commercial jOOQ edition for occurrences of "test", "assert" or other common Java testing phrases, but I only found results in jOOQ Examples, which seem to be basic usage examples rather than integration tests I suppose jOOQ to have.
Googling didn't work for me (probably) due to the sources being exclusive to the commercial editions.
Is jOOQ integration test suites source code available?
jOOQ's integration tests aren't available to anyone, including paying customers. They're completely closed source.
But you're not specifically looking for tests, but rather for more detailed examples, I suspect? There's a demo here, which probably answers most of your questions:
The demo is much better suited than the integration tests anyway, given how many weird and quirky edge cases the tests cover, whereas the demo aims at showing how to use jOOQ, instead.
