Launching unittests with arguments python -m unittest

To launch unittests with arguments in Python, you can use the following command:

python -m unittest [options] [test modules]

Here are some common options you can use:

• -v or --verbose: Verbose output, showing more details about the tests being run.
• -f or --failfast: Stop the test run on the first failure or error.
• -b or --buffer: Buffer the standard output and standard error streams during the test run.
• -k PATTERN: Only run tests that match the given pattern.
• -s START_DIR: Directory to start discovery ('.' default).
• -p PATTERN: Pattern to match test files ('test*.py' default).

For example, to run unittests in verbose mode and only run tests that match a specific pattern, you can use the following command:

python -m unittest -v -k test_pattern

Replace test_pattern with the specific pattern you want to match.
