NAME

       tox - virtualenv-based automation of test activities

SYNOPSIS

       tox [options] [args ...]

DESCRIPTION

       tox is a generic virtualenv management and test command line tool you can use for:

       • checking your package installs correctly with different Python versions and interpreters

       • running your tests in each of the environments, configuring your test tool of choice

       • acting as a frontend to Continuous Integration servers, greatly reducing boilerplate and merging CI and
         shell-based testing.

OPTIONS

   positional arguments:
       args   additional arguments available to command positional substitution (default: None)

   optional arguments:
       --version

              show help about options (default: False)

       --help-ini, --hi
              show help about ini-names (default: False)

       -v     increase  verbosity  of  reporting  output.-vv  mode  turns  off  output  redirection  for package
              installation, above level two verbosity flags are passed through to  pip  (with  two  less  level)
              (default: 0)

       -q     progressively silence reporting output. (default: 0)

       --showconfig
              show configuration information for all environments. (default: False)

       -l, --listenvs
              show list of test environments (with description if verbose) (default: False)

       -a, --listenvs-all
              show list of all defined environments (with description if verbose) (default: False)

       -c CONFIGFILE
              config file name or directory with 'tox.ini' file. (default: None)

       -e envlist
              work against specified environments (ALL selects all). (default: None)

       --notest
              skip invoking test commands. (default: False)

       --sdistonly
              only perform the sdist packaging activity. (default: False)

       -p VAL, --parallel VAL
              run  tox  environments  in  parallel,  the  argument  controls  limit: all, auto - cpu count, some
              positive number, zero is turn off (default: 0)

       -o, --parallel-live
              connect to stdout while running environments (default: False)

       --parallel--safe-build
              (deprecated) ensure two tox builds can run in parallel (uses a lock file in the tox  workdir  with
              .lock extension) (default: False)

       --installpkg PATH
              use specified package for installation into venv, instead of creating an sdist. (default: None)

       --develop
              install package in the venv using 'setup.py develop' via 'pip -e .' (default: False)

       -i URL, --index-url URL
              set  indexserver  url  (if  URL  is  of  form  name=url  set  the  url for the 'name' indexserver,
              specifically) (default: None)

       --pre  install pre-releases and development versions of dependencies. This will pass the --pre option  to

       -r, --recreate
              force recreation of virtual environments (default: False)

       --result-json PATH
              write  a  json  file  with detailed information about all commands and results involved. (default:
              None)

       --hashseed SEED
              set PYTHONHASHSEED to SEED before running commands. Defaults to a random integer in the range  [1,
              4294967295] ([1, 1024] on Windows). Passing 'noset' suppresses this behavior. (default: None)

       --force-dep REQ
              Forces  a certain version of one of the dependencies when configuring the virtual environment. REQ

       --sitepackages
              override sitepackages setting to True in all envs (default: False)

       --alwayscopy
              override alwayscopy setting to True in all envs (default: False)

       -s [val], --skip-missing-interpreters [val]
              don't fail tests for missing interpreters: {config,true,false} choice (default: config)

       --workdir PATH
              tox working directory (default: None)
