I found the same issue but for classes with only one test

[jdneo]

The root cause is same as #515. Let's track this in #515

This should be fixed with #536

Reopen this issue because it can still be reproduced.

For TestNG project:

1. Open a TestNG project in Vscode, for example: https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-testng
2. Manually add a inner class
3. Trigger test from a level that contains an inner class in test explorer

Result:
All tests will be skipped

For Junit5 project
Trigger test from a level that contains an inner class in test explorer, only the inner class case will be skipped.

For Junit4 project
Trigger test from a level that contains an inner class in test explorer, all cases can be run successfully.

There is another test skipped issue of inner class here:
For Junit5 or TestNG project, if triggering test from inner class codelens or inner class level in test explorer, the inner class case will be skipped, but works on Junit4 project.
