py.test

NAME

py.test - pylib test runner

SYNOPSIS

py.test [option] [query] [filenames of tests...]

DESCRIPTION

This manual page documents briefly the py.test command.

This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has documentation in html available in /usr/share/doc/python-codespeak-lib/py/doc/test.html.

py.test is a program that runs tests in a module or directory specified on the command line. It looks for functions and methods with names starting with 'test_' and run those methods. Assertions about test outcomes are done via the standard 'assert' statement.

OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. This list may however be incomplete as test suits and aditional plugins can add more options.

-h --help

Displays a help message including all the available options.

-x --exitfirst

exit instantly on first error or failed test.

-k KEYWORD

only run test items matching the given space separated keywords. precede a keyword with '-' to negate. Terminate the expression with ':' to treat a match as a signal to run all subsequent tests.

--capture=method

set capturing method during tests: fd (default)|sys|no.

-s

shortcut for --capture=no.

--pdb

start pdb (the Python debugger) on errors.

-v --verbose

show more info, valid: skipped,xfailed

--tb=style

--junitxml=path

create junit-xml style report file at given path.

--collectonly

--basetemp=dir

--no-assert

disable python assert expression reinterpretation.

--genscript=path

create standalone py.test script at given target path.

-f --looponfail

(requires xdist plugin) run tests, re-run failing test set until all pass.

-n numprocesses

(requires xdist plugin) shortcut for '--dist=load --tx=NUM*popen'

--boxed

(requires xdist plugin) box each test run in a separate process.

--dist=distmode

(requires xdist plugin) set mode for distributing tests to exec environments. each: send each test to each available environment. load: send each test to available environment. (default) no: run tests inprocess, don't distribute.

--tx=xspec
