usage: testproject.py [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'. 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.
-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              run pytest in strict mode, warnings become errors.
-c file               load configuration from `file` instead of trying to
locate one of the implicit configuration files.
--fixtures, --funcargs
show available fixtures, sorted by plugin appearance
--pdb                 start the interactive Python debugger on errors.
--capture=method      per-test capturing method: one of fd|sys|no.
-s                    shortcut for --capture=no.
--runxfail            run tests even if they are marked xfail
