scala tests like test("...") not recognized most of the time

[kostaskougios]

Describe the bug

Most of the time scala tests are not recognised (I am using vscode). I can still run a test class but each test is not reported, instead the error for every test is reported at the class level.

i would expect to see the green circle near the test like below:

But most of the time I don't see it. clean-build, re-import, restart of the IDE most of the time doesn't help but some times it does.

The tests are randomly recognised at later times.

Note: the code compiles correctly when the issue occurs.

Expected behavior

The tests to be recognised as per below:

Operating system

macOS

Editor/Extension

VS Code

Version of Metals

v1.39.6 (pre-release)

Extra context or search terms

scalatest

Note I don't see anything strange in .metals/bsp.trace.json when the issue occurs

I can confirm here, vscode-1.94.2, metals-v1.39.0. only test classes are visible in test explorer and its impossible to run single test-case. Tests implemented with scalatest

and here is idea for comparision

[tgodzik]

I think another thing we might want to use is the presentation compiler for finding tests cases, which should be much more error proof

Btw the issue is not limited only to test cases. @main def myMain() method recognition is on and off a lot of the time. (for code that compiles fine)
