python - 如何确保只有在 pytest 中明确要求时才运行带有标记的测试？

Question

我用适当的标记标记了一些测试。如果我运行 pytest，默认情况下它们会运行，但我想默认跳过它们。我知道的唯一选择是在调用 pytest 时明确说“不是标记”，但我希望它们不会默认运行，除非在命令行明确询问标记。

对 Control skipping of tests according to command line option 中的示例稍作修改:

# conftest.py

import pytest


def pytest_collection_modifyitems(config, items):
    keywordexpr = config.option.keyword
    markexpr = config.option.markexpr
    if keywordexpr or markexpr:
        return  # let pytest handle this

    skip_mymarker = pytest.mark.skip(reason='mymarker not selected')
    for item in items:
        if 'mymarker' in item.keywords:
            item.add_marker(skip_mymarker)

示例测试:

import pytest


def test_not_marked():
    pass


@pytest.mark.mymarker
def test_marked():
    pass

使用标记运行测试:

$ pytest -v -k mymarker
...
collected 2 items / 1 deselected / 1 selected
test_spam.py::test_marked PASSED
...

或者:

$ pytest -v -m mymarker
...
collected 2 items / 1 deselected / 1 selected
test_spam.py::test_marked PASSED
...

没有标记:

$ pytest -v
...
collected 2 items

test_spam.py::test_not_marked PASSED
test_spam.py::test_marked SKIPPED
...
