pytest-cov-exclude 0.0.5

Installation

Install with pip:

$ pip install pytest-cov-exclude

pytest-cov-exclude requires Pytest 2.8 or later. It is compatible with Python 2.7, 3.3, 3.4, 3.5, as well as PyPy. It does not work on PyPy 3 due to an unknown bug with the coverage data generated.

Usage

The first time you run your test suite, per-test coverage is enabled and the suite will take a little bit longer than usual:

$ py.test

==================== test session starts =====================

# Test output...

================ MANY passed in MANY seconds =================

Now when you re-run the test suite, all tests should have been excluded:

$ py.test

==================== test session starts =====================

# Test output...

=============== MANY deselected in FEW seconds ===============

If a test fails, it will re-run even if nothing changed in order to preserve the general failure status of the test suite.

@pytest.mark.external_dependencies
def test_something():
    # Run tests from external data files

$ py.test -p no:cov-exclude  # Disable the plugin

$ py.test --cache-clear  # Clear pytest's cache

Compatibility

As stated earlier, this plugin requires Pytest 2.8 or later since it depends on the new cache module.

While PyPy is supported, the ujson library used for faster serialization/deserialization is not available, so a fallback to the default JSON implementation is used instead. Because of this, the tests might actually run slower with this plugin under PyPy.
