usage: pytest [options] [file_or_dir] [file_or_dir] [...]

positional arguments:
  file_or_dir

general:
  -k EXPRESSION         Only run tests matching the given keyword expression, e.g. -k 'test_method
                        or test_other', -k 'not (slow or network)'.
                        Names in the expression are matched case-insensitively as substrings of the
                        test's keywords, which are:
                        - its own name, including any parametrization id
                        - the names of its class, module and directories
                        - the names of the markers applied to it or to its parents
                        - attributes assigned directly to the test function
                        - any names in its 'extra_keyword_matches' set
                        Use -m to match marker names exactly, including their arguments.
  -m MARKEXPR           Only run tests matching given mark expression. For example: -m 'mark1 and
                        not mark2'.
  --markers             show markers (builtin, plugin and per-project ones).
  -x, --exitfirst       Exit instantly on first error or failed test
  --maxfail=num         Exit after first num failures or errors
  --strict-config       Enables the strict_config option
  --strict-markers      Enables the strict_markers option
  --strict              Enables the strict option
  --fixtures, --funcargs
                        Show available fixtures, sorted by plugin appearance (fixtures with leading
                        '_' are only shown with '-v')
  --fixtures-per-test   Show fixtures per test
  --pdb                 Start the interactive Python debugger on errors or KeyboardInterrupt
  --pdbcls=modulename:classname
                        Specify a custom interactive Python debugger for use with --pdb.For example:
                        --pdbcls=IPython.terminal.debugger:TerminalPdb
  --trace               Immediately break when running each test
  --capture=method      Per-test capturing method: one of fd|sys|no|tee-sys
  -s                    Shortcut for --capture=no
  --runxfail            Report the results of xfail tests as if they were not marked
  --lf, --last-failed   Rerun only the tests that failed at the last run (or all if none failed)
  --ff, --failed-first  Run all tests, but run the last failures first. This may re-order tests and
                        thus lead to repeated fixture setup/teardown.
  --nf, --new-first     Run tests from new files first, then the rest of the tests sorted by file
                        mtime
  --cache-show=[CACHESHOW]
                        Show cache contents, don't perform collection or tests. Optional argument:
                        glob (default: '*').
  --cache-clear         Remove all cache contents at start of test run
  --lfnf={all,none}, --last-failed-no-failures={all,none}
                        With ``--lf``, determines whether to execute tests when there are no
                        previously (known) failures or when no cached ``lastfailed`` data was found.
                        ``all`` (the default) runs the full test suite again. ``none`` just emits a
                        message about no known failures and exits successfully.
  --sw, --stepwise      Exit on test failure and continue from last failing test next time
  --sw-skip, --stepwise-skip
                        Ignore the first failing test but stop on the next failing test. Implicitly
                        enables --stepwise.
  --sw-reset, --stepwise-reset
                        Resets stepwise state, restarting the stepwise workflow. Implicitly enables
                        --stepwise.
