我喜欢一般的“测试步骤”构想。我将其称为“增量”测试,在功能测试方案恕我直言中最有意义。
这是一个不依赖pytest内部细节的实现(官方钩子扩展除外)。复制到您的conftest.py
:
import pytest
def pytest_runtest_makereport(item, call):
if "incremental" in item.keywords:
if call.excinfo is not None:
parent = item.parent
parent._prevIoUsFailed = item
def pytest_runtest_setup(item):
prevIoUsFailed = getattr(item.parent, "_prevIoUsFailed", None)
if prevIoUsFailed is not None:
pytest.xfail("prevIoUs test Failed (%s)" % prevIoUsFailed.name)
如果您现在有一个像这样的“ test_step.py”:
import pytest
@pytest.mark.incremental
class TestUserHandling:
def test_login(self):
pass
def test_modification(self):
assert 0
def test_deletion(self):
pass
然后运行,如下所示(使用-rx报告xfail原因):
(1)hpk@t2:~/p/pytest/doc/en/example/teststep$ py.test -rx

我在这里使用“ xfail”,因为跳过是针对错误的环境或缺少依赖项,错误的解释器版本。
编辑:请注意,您的示例和我的示例都无法直接用于分布式测试。为此,pytest- xdist插件需要发展一种方法来定义要整体出售给一个测试从属的组/类,而不是通常将类的测试功能发送给不同从属的当前模式。
