Hi Andreas, thank you for your reply! Indeed, I would like to test the fuzzer code. The test script collects 37 base tests but produced 0 non-filtered tests.
Is this a right output below and why there is 0 non-filtered tests ? >>> Autodetected: pointer_compression >>> Loading test suite: fuzzer >>> Running tests for x64.release >>> Running with test processors [00:00|% 0|+ 0|- 0]: Done >>> 37 base tests produced 0 (0%) non-filtered tests >>> 0 tests ran Thank you again!
