usage: pytest [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 evaluatable
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. 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-markers, --strict
markers not registered in the `markers` section of the
configuration file raise errors.
-c file load configuration from `file` instead of trying to
locate one of the implicit configuration files.
--continue-on-collection-errors
Force test execution even if collection errors occur.
--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'.
--fixtures, --funcargs
show available fixtures, sorted by plugin appearance
(fixtures with leading '_' are only shown with '-v')
--fixtures-per-test show fixtures per test
--import-mode={prepend,append}
prepend/append to sys.path when importing test modules,
default is to prepend.
--pdb start the interactive Python debugger on errors or
KeyboardInterrupt.
--pdbcls=modulename:classname
start a custom interactive Python debugger on errors.
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}
which tests to run with no previously (known) failures.
--sw, --stepwise exit on test failure and continue from last failing test
next time
--stepwise-skip ignore the first failing test but stop on the next
failing test
reporting:
--durations=N show N slowest setup/test durations (N=0 for all).
-v, --verbose increase verbosity.
-q, --quiet decrease verbosity.
--verbosity=VERBOSE set verbosity. Default is 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).
--tb=style traceback print mode (auto/long/short/line/native/no).
--show-capture={no,stdout,stderr,log,all}
Controls how captured stdout/stderr/log is shown on
failed tests. Default is 'all'.
--full-trace don't cut any tracebacks (default is to cut).
--color=color color terminal output (yes/no/auto).
--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
--result-log=path DEPRECATED path for machine-readable result log.
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
--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 ImportErrors
--doctest-continue-on-failure
for a given doctest, continue to run after the first
failure
test session debugging and configuration:
--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.
-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`.
--trace-config trace considerations of conftest.py files.
--debug store internal tracing debug information in
'pytestdebug.log'.
-o OVERRIDE_INI, --override-ini=OVERRIDE_INI
override ini option with "option=value" style, e.g. `-o
xfail_strict=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

set which warnings to report, see -W option of python
itself.
