1. All you test should be added to tests/unit/cli/test_cli.sh to trigger unit test.
2. Also to reduce the repetition of code, it is recommended that you write a separate bash file for voice download in the single test, and after downloading the voice, read it separately from different python files.
3. To ensure accurate alignment, it is recommended to add the current alignment accuracy value in the single measurement annotation, normally fp32 requires 1e-6.
4. Remove symbols and commented out useless code from single test file names.

Take an overlook at the import part of post.py. Some of that still have unused import, also duplicate pkg need to find in requirement.
