pyright-cov 0.2.2

Run Pyright and enforce minimum type coverage

Pyright-cov

Enforce minimum type coverage!

pyright-cov is a tool which you can use to enforce minimum type coverage in your projects.

Installation

pip install pyright-cov

Usage

In a virtual environment in which you have a local install of a library foo, you can ensure that foo is type-complete with:

pyright-cov --verifytypes foo --ignoreexternal

This will fail (i.e. exit 1) if your type coverage is less than 100%. To set a lower threshold, such as 60%:

pyright-cov --verifytypes foo --ignoreexternal --fail-under 60

To exclude symbols whose names match a given (glob) pattern, use --exclude-like, for example:

pyright-cov --verifytypes foo --ignoreexternal --exclude-like "*.tests.*"

Additional command-line flags are passed to Pyright.
