trial --help

trial loads and executes a suite of unit tests, obtained from modules and packages listed on the command line. The --help option prints out a usage message to standard output.

-s, --summary

Print out just a machine-parseable summary of the results.

-v, --verbose

Be more verbose. Without this option, trial prints out a single character for each test. (e.g. An 'F' for a failure, a '.' for a success, a 'S' for skipped test, a 'T' for a todo and '!' for unexpected success). With this option, trial prints a single line for each test. This is especially useful for gauging how long each test takes.

-o, --bwverbose

Be verbose, but do not attempt to use colors (more log-file friendly)

-j, --jelly

Report results in a machine-readable jelly stream.

--timing

Report results with timing information for each test.

--tbformat <format>

Format to display tracebacks with. Valid values are 'plain' and 'emacs', default being 'plain'.

-m, --module <module>

Module containing test cases.

--testmodule <module>

Find the test case for a named file

-p, --package <package>

Package containing modules that contain test cases. trial loads modules named 'test_' within the given package.

-l, --logfile <logfile>

Log exceptions (and other things) to the given logfile.

-r, --reactor <reactor>

Use this reactor for running the tests. The reactor names are the same as those accepted by twistd: c, qt, gtk2, and so on.

--coverage <coverdir>

Generate coverage information in the given directory (relative to _trial_temp). Requires Python 2.3.3.

-b, --debug

Run the tests in the Python debugger. Also does post-mortem debugging on exceptions.

-R, --recurse

Recursively search the specified packages for test modules.
