usage: py.test [options] [file_or_dir] [file_or_dir] [...] positional arguments: file_or_dir general: -k EXPRESSION Only run tests which match the given substring expression. An expression is a Python evaluable expression where all names are substring-matched against test names and their parent classes. Example: -k 'test_method or test_other' matches all test functions and classes whose name contains 'test_method' or 'test_other', while -k 'not test_method' matches those that don't contain 'test_method' in their names. -k 'not test_method and not test_other' will eliminate the matches. Additionally keywords are matched to classes and functions containing extra names in their 'extra_keyword_matches' set, as well as functions which have names assigned directly to them. The matching is case-insensitive. -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. Reporting: --durations=N Show N slowest setup/test durations (N=0 for all) --durations-min=N Minimal duration in seconds for inclusion in slowest list. Default: 0.005 (or 0.0 if -vv is given). -v, --verbose Increase verbosity --no-header Disable header --no-summary Disable summary --no-fold-skipped Do not fold skipped tests in short summary. --force-short-summary Force condensed summary output regardless of verbosity level. -q, --quiet Decrease verbosity --verbosity=VERBOSE Set verbosity. Default: 0. -r chars Show extra test summary info as specified by chars: (f)ailed, (E)rror, (s)kipped, (x)failed, (X)passed, (p)assed, (P)assed with output, (a)ll except passed (p/P), or (A)ll. (w)arnings are enabled by default (see --disable-warnings), 'N' can be used to reset the list. (default: 'fE'). --disable-warnings, --disable-pytest-warnings Disable warnings summary -l, --showlocals Show locals in tracebacks (disabled by default) --no-showlocals Hide locals in tracebacks (negate --showlocals passed through addopts) --tb=style Traceback print mode (auto/long/short/line/native/no) --xfail-tb Show tracebacks for xfail (as long as --tb != no) --show-capture={no,stdout,stderr,log,all} Controls how captured stdout/stderr/log is shown on failed tests. Default: all. --full-trace Don't cut any tracebacks (default is to cut) --color=color Color terminal output (yes/no/auto) --code-highlight={yes,no} Whether code should be highlighted (only if --color is also enabled). Default: yes. --pastebin=mode Send failed|all info to bpaste.net pastebin service --junit-xml=path Create junit-xml style report file at given path --junit-prefix=str Prepend prefix to classnames in junit-xml output pytest-warnings: -W PYTHONWARNINGS, --pythonwarnings=PYTHONWARNINGS Set which warnings to report, see -W option of Python itself collection: --collect-only, --co Only collect tests, don't execute them --pyargs Try to interpret all arguments as Python packages --ignore=path Ignore path during collection (multi-allowed) --ignore-glob=path Ignore path pattern during collection (multi-allowed) --deselect=nodeid_prefix Deselect item (via node id prefix) during collection (multi-allowed) --confcutdir=dir Only load conftest.py's relative to specified dir --noconftest Don't load any conftest.py files --keep-duplicates Keep duplicate tests --collect-in-virtualenv Don't ignore tests in a local virtualenv directory --continue-on-collection-errors Force test execution even if collection errors occur --import-mode={prepend,append,importlib} Prepend/append to sys.path when importing test modules and conftest files. Default: prepend. --doctest-modules Run doctests in all .py modules --doctest-report={none,cdiff,ndiff,udiff,only_first_failure} Choose another output format for diffs on doctest failure --doctest-glob=pat Doctests file matching pattern, default: test*.txt --doctest-ignore-import-errors Ignore doctest collection errors --doctest-continue-on-failure For a given doctest, continue to run after the first failure test session debugging and configuration: -c FILE, --config-file=FILE Load configuration from `FILE` instead of trying to locate one of the implicit configuration files. --rootdir=ROOTDIR Define root directory for tests. Can be relative path: 'root_dir', './root_dir', 'root_dir/another_dir/'; absolute path: '/home/user/root_dir'; path with variables: '$HOME/root_dir'. --basetemp=dir Base temporary directory for this test run. (Warning: this directory is removed if it exists.) -V, --version Display pytest version and information about plugins. When given twice, also display information about plugins. -h, --help Show help message and configuration info -p name Early-load given plugin module name or entry point (multi-allowed). To avoid loading of plugins, use the `no:` prefix, e.g. `no:doctest`. See also --disable-plugin-autoload. --disable-plugin-autoload Disable plugin auto-loading through entry point packaging metadata. Only plugins explicitly specified in -p or env var PYTEST_PLUGINS will be loaded. --trace-config Trace considerations of conftest.py files --debug=[DEBUG_FILE_NAME] Store internal tracing debug information in this log file. This file is opened with 'w' and truncated as a result, care advised. Default: pytestdebug.log. -o OVERRIDE_INI, --override-ini=OVERRIDE_INI Override configuration option with "option=value" style, e.g. `-o strict_xfail=True -o cache_dir=cache`. --assert=MODE Control assertion debugging tools. 'plain' performs no assertion debugging. 'rewrite' (the default) rewrites assert statements in test modules on import to provide assert expression information. --setup-only Only setup fixtures, do not execute tests --setup-show Show setup of fixtures while executing tests --setup-plan Show what fixtures and tests would be executed but don't execute anything logging: --log-level=LEVEL Level of messages to catch/display.
