Can you point me to the location of the tests? Thx! 😄

@erinlkolp Hello, this ticket mainly about managed component tests: https://github.com/percona/pmm/tree/main/managed So almost every package there has _test.go files. Some tests rely on database state, so not every test can be parallelized. However a lot of them can.

Managed tests works only inside devcontainer, so your actions will be like:

1. clone pmm repo git clone [email protected]:percona/pmm.git
2. run make env-up in the project root folder
3. run make env to step in devcontainer
4. run cd managed to change root to the managed folder
5. modify tests
6. run make test to run managed tests
7. check that all tests are passing

@artemgavrilov Thank you so much! My son and I will be taking a crack at this!
