# PyTest plugin. Pytest is a fantastic test framework for Python code. AnyPyTools provides a pytest plugin for running and testing AnyBody models. The plugin make pytest collect and run AnyScript files with a `test_` prefix (e.g. `test_mymodel.any`). Once loaded the plugin will attempt to execute a `Main.RunTest` operation if it exists. If the models produce error while loading and running, the framework considers it a failed test. ```{eval-rst} .. automodule:: anypytools.pytest_plugin :members: :noindex: ```
