无法使 pytest 依赖项适用于不同的模块

Question

在 and the doc 之后，我正在尝试使文件之间的测试相互依赖：

test_connectivity.py:

@pytest.mark.dependency(depends=["test_services_up.py::test_sssss"], scope="session")
def test_aaa():
    assert False


@pytest.mark.dependency(depends=["tests/test_services_up.py::test_sssss"], scope="session")
def test_bbb():
    assert False

@pytest.mark.dependency(depends=["atp/tests/test_services_up.py::test_sssss"], scope="session")
def test_ccc():
    assert False

和test_services_up.py:

@pytest.mark.dependency()
def test_sssss():
    assert True

文件夹结构：

    atp
    ----|tests
    --------|test_connectivity.py
    --------|test_services_up.py

输出：

> ssh://me@host:port~/src/uv-fleet-atp/venv/bin/python -u ~/.pycharm_helpers/pycharm/_jb_pytest_runner.py --path ~/src/uv-fleet-atp/atp/tests

如何不跳过相关测试？

Answer 1

如评论中所述，pytest-dependency 不对测试进行排序，它依赖于以正确顺序执行的测试才能使依赖项起作用。这背后的原因是 pytest-dependency 被认为只做一件事，也就是根据测试关系跳过测试。排序可以通过相应地安排测试来手动完成（例如，调整名称，大多数用户似乎都这样做），或者依赖于排序插件。对此有过争议性的讨论，当然不是每个人都同意这种哲学（我倾向于同意），但最终由插件作者决定。

pytest-order works together with pytest-dependency. If it is installed and you run your tests with the option --order-dependencies 如果需要，它将使用 dependency 标记对您的测试进行排序。像往常一样，您可以将选项添加到 pytest.ini:

[pytest]
; always order tests with dependency markers
addopts = --order-dependencies

对于找不到的测试，应该发出相应的警告。

我是 pytest-order.
