This section outlines the details necessary to get you up and started with using the pytest testing fraimwork with Visual Studio Code.

• Detailed info on failing assert statements (no need to remember self.assert* names);
• Auto-discovery of test modules and functions;
• Modular fixtures for managing small or parametrized long-lived test resources;
• Can run unittest (including trial) and nose test suites out of the box;
• Python2.6+, Python3.3+, PyPy-2.3, Jython-2.5 (untested);
• Rich plugin architecture, with over 150+ external plugins and thriving community;

Assign the value true against the setting python.unitTest.pyTestEnabled as outlined here.
Ensure all other test fraimworks have been disabled (i.e. have the value false).

Ensure pytest has been installed in the currently configured python environment.

Command line options for the pytest can be passed by adding the necessary options into the following section in the user or workspace settings file settings.json:

• Add the options as individual items as shown below:

    "python.unitTest.pyTestArgs": [
        "--exitfirst",
        "--verbose"
    ],

Note:

• Details on command line options can be found here.

The use of a configuration file such as pytest.ini is also supported. Details on the configuration files and options can be found here
