not all tests are run and nothing is outputed

**Describe the bug**
when I run the tests it says noting
when I list the tests (-l) I see all the tests (5 tests in may case)
when I execute the tests with --success I only see 2 tests being ran
on test fails, but I have to launch it explicitly to see it fail

**Expected behavior**
all test should be run if no parameters are given
