pytest-yapf3 0.4.0

Validate your Python file format with yapf

pytest-yapf3

Validate your Python file format with yapf.

This is a pytest plugin, which make sure your python file is exactly formatted by yapf, or it will crash when running pytest.

Install

pip install pytest-yapf3

Usage

Modify setup.cfg (or pytest.ini):

[tool:pytest]
addopts =
    --yapf
    --yapfdiff
yapf-ignore =
    setup.py
    src/package/auto_generated/**.py

Add --yapf to pytest configuration addopts. By default, only line summaries is displayed. With --yapfdiff, a full text of yapf -d is displayed.

An optional yapf-ignore is supported. Each line specifies a glob pattern of files which should not check yapf.
