pytest-annotate
A pytest plugin that automatically generates PyAnnotate type annotations from your test runs.
What is pytest-annotate?
pytest-annotate is a pytest plugin that automatically generates PyAnnotate-compatible type annotations by observing runtime behavior during test execution. It solves the problem of manually adding type hints to large Python codebases by capturing type information from actual test runs and outputting it in a format that can be automatically applied.
Python developers working on codebases that need type annotations added, particularly those using pytest for testing and wanting to integrate type hinting into their workflow.
Developers choose pytest-annotate because it automates the tedious process of adding type annotations by leveraging existing test suites, reducing manual effort while ensuring annotations reflect actual usage patterns observed during testing.
