No tests found

[elect86]

as titled, fresh cloned, tried to run the test(s) via Idea gui:

Execution failed for task ':test'.
No tests found for given includes: [org.example.detekt.MyRuleSpec](--tests filter)
Try:
Run with --stacktrace option to get the stack trace.
Run with --info or --debug option to get more log output.
Run with --scan to get full insights.

If I switch to running test with Idea instead:

org.junit.runners.model.InvalidTestClassError: Invalid test class 'org.example.detekt.MyRuleSpec':

1. Test class should have exactly one public zero-argument constructor

I just cloned the repo and I ran ./gradlew test and it worked. What are you using to run the tests?

That's strange. We use Junit5 on this project, we don't use JUnit4.

What about running via Idea gui instead?

However, what output do you see? I have this:

elect@5800x:~/IdeaProjects/detekt-custom-rule-template$ ./gradlew test

BUILD SUCCESSFUL in 865ms
4 actionable tasks: 2 executed, 2 up-to-date

Anyway, if I change the first test in order to make it fail:
assertThat(findings).hasSize(2)
I still see the very same output

Ooops! Good catch! I can see the error now.

I found the issue. The import of @Test points to JUnit4 🤦. I didn't expect that truth will import that dependency (google/truth#333). I'm still looking for a good assertion library for kotlin. I like hamscrest but they really heavily on the function is(...) and on kotlin it should be quoted as `is`(...).

What about kotest?

Nice idea: #25
