If that debugger is pdb, will load '.pdbrc' from current directory if it exists. -B, --debug-stacktraces Report Deferred creation and callback stack traces --nopm don't automatically jump into debugger for postmorteming of exceptions -n, --dry-run do everything but run the tests --profile Run tests under the Python profiler -u, --until-failure Repeat test until it fails -o, --order= Specify what order to run test cases and methods. See --help-orders for more info. -z, --random= Run tests in random order using the specified seed --temp-directory= Path to use as working directory for tests. [default: _trial_temp] --reporter= The reporter to use for this test run. See --help- reporters for more info. [default: verbose] --debugger= the fully qualified name of a debugger to use if --debug is passed [default: pdb] -l, --logfile= log file name [default: test.log] -j, --jobs= Number of local workers to run, a strictly positive integer. --disablegc Disable the garbage collector --without-module= Fake the lack of the specified modules, separated with commas. -r, --reactor= Which reactor to use (see --help-reactors for a list of possibilities) --spew Print an insanely verbose log of everything that happens. Useful when debugging freezes or locks in complex code. --testmodule= Filename to grep for test cases (-*- test-case-name). --version Display Twisted version and exit. --coverage Generate coverage information in the coverage file in the directory specified by the temp-directory option. --help-reactors Display a list of possibly available reactor names. --tbformat= Specify the format to display tracebacks with. Valid formats are 'plain', 'emacs', and 'cgitb' which uses the nicely verbose stdlib cgitb.text function --recursionlimit= see sys.setrecursionlimit() trial loads and executes a suite of unit tests, obtained from modules, packages and files listed on the command line.
