better_coverage

better_coverage is a pytest plugin that displays pytest-cov coverage results in Jest/Istanbul's console format with a directory tree structure.

Why?

Using better_coverage lets you see coverage in Jest's familiar table format right in your terminal. The reporter organizes files into a directory tree, shows uncovered line ranges (e.g., 5-12,18), and applies the same color coding as Jest so your Python coverage reports look exactly like your JavaScript ones.

Usage

Add the package to your project:

pip install better-coverage

Then run your tests with coverage:

pytest --cov=your_package --cov-report=xml

The Jest-style coverage table will automatically appear at the end of your test run.

Options

The plugin automatically detects terminal width and formats output accordingly. Coverage data is read from pytest-cov, so use standard pytest-cov options:

pytest --cov=your_package --cov-report=xml --cov-branch

Use --cov-branch to enable branch coverage reporting.
