Environment Variables ​

Environment variables that can be used to change pytest’s behavior.

CI ​

When set (regardless of value), pytest acknowledges that is running in a CI process. Alternative to BUILD_NUMBER variable.

BUILD_NUMBER ​

When set (regardless of value), pytest acknowledges that is running in a CI process. Alternative to CI variable.

PYTEST_ADDOPTS ​

This contains a command-line (parsed by the py:mod:shlex module) that will be prepended to the command line given by the user, see Builtin configuration file options for more information.

PYTEST_CURRENT_TEST ​

This is not meant to be set by users, but is set by pytest internally with the name of the current test so other processes can inspect it, see PYTEST_CURRENT_TEST environment variable for more information.

PYTEST_DEBUG ​

When set, pytest will print tracing and debug information.

PYTEST_DISABLE_PLUGIN_AUTOLOAD ​

When set, disables plugin auto-loading through setuptools entrypoints. Only explicitly specified plugins will be loaded.

PYTEST_PLUGINS ​

Contains comma-separated list of modules that should be loaded as plugins:

export PYTEST_PLUGINS=mymodule.plugin,xdist

export PYTEST_PLUGINS=mymodule.plugin,xdist

PYTEST_THEME ​

Sets a pygment style to use for the code output.

PYTEST_THEME_MODE ​

Sets the PYTEST_THEME to be either dark or light.

PY_COLORS ​

When set to 1, pytest will use color in terminal output. When set to 0, pytest will not use color. PY_COLORS takes precedence over NO_COLOR and FORCE_COLOR.

NO_COLOR ​

When set (regardless of value), pytest will not use color in terminal output. PY_COLORS takes precedence over NO_COLOR, which takes precedence over FORCE_COLOR. See no-color.org for other libraries supporting this community standard.

FORCE_COLOR ​

When set (regardless of value), pytest will use color in terminal output. PY_COLORS and NO_COLOR take precedence over FORCE_COLOR.
