The DisciplineFSuite is probably meant to be used with IOSuite or SimpleIOSuite to run discipline tests with effects. For example:

object MyTests extends SimpleIOSuite with DisciplineFSuite[IO] {
 ...
}

However, it has its own spec function that replaces the function in IOSuite. This means that tests declared with the IOSuite DSL, such as with the test and pureTest functions, aren't run.

The TestName filtering logic in IOSuite is also not used. such as "mytest".ignore, or CI only checks, aren't performed.

This can be reproduced with scala cli:
