How to pass multiple pytest command line options in the run configuration

Question

How to pass multiple pytest command line options in PyCharm?

Problem

Setting the pytest logging options --log-level=DEBUG --log-cli=True --log-cli-level=DEBUG fails with the error with the PyCharm Run Configuration.

enter image description here

Launching pytest with arguments --log-level=DEBUG --log-cli=True --log-cli-level=DEBUG ****/test_040_objective_sigmoid.py in ****

ERROR: usage: _jb_pytest_runner.py [options] [file_or_dir] [file_or_dir] [...]
_jb_pytest_runner.py: error: unrecognized arguments: --log-cli=True
  inifile: None
  rootdir: ****

With single argument, it runs without an error.

Launching pytest with arguments --log-level=DEBUG ****test_040_objective_sigmoid.py in ****

When running the pytest from command line, the pytest logging options work.

$ pytest --log-level=DEBUG --log-cli=True --log-cli-level=DEBUG --verbose --cache-clear -x ${DIR}

pytest uses a mixture of single - and double -- hyphens preceding the command line options, some are used without an hyphen. In your example only --log-level uses a double hyphen.

The remaining two options log_cli and log_cli_level are written without any leading hyphen and have an underscore in the middle of the name. Those two are also "Configuration Options" and may need to be prefixed with -o.

A complete reference can be found in Command-line Flags.

So instead of:

--log-level=DEBUG --log-cli=True --log-cli-level=DEBUG

try:

--log-level=DEBUG -o log_cli=True -o log_cli_level=DEBUG
