I'm getting error from: pytest test_01.py -v -rA --profile

Question

To test my code I ran the following command in the directory where the source codes are located and I got the following error:

pytest test_01.py -v -rA --profile

ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: --profile
  inifile: None

Answer 1

You didn't install the pytest-profiling library. To install it, open anaconda prompt and run the following command,

conda install -c conda-forge pytest-profiling

Answer 2

If you aren't using anaconda use pip install pytest-profiling in the command prompt

Answer 3

The pytest isn't working because it lacks the extension itself (inifile : None means it doesn't have a file to begin from).

You should just have to go to the HW1 on Q2A and, inside of anaconda prompt, insert the code to the right of the necessary extensions( so conda install etc. etc.).

Remember that there are both pytest timeout and profiling so maybe you only installed one.
