Root Cause

在测试中直接调用fixture函数，而不是作为参数注入，导致pytest报错。

generic

中文

测试中直接调用了fixture函数，而非通过参数注入。

Workarounds

  1. 100% success 
    def test_example(db):
    assert db is not None
  2. 90% success 
    def test_example(request):
    db = request.getfixturevalue('db')

Dead Ends

Common approaches that don't work:

  1. 80% fail

    失去fixture的依赖注入和清理功能。

  2. 90% fail

    直接调用返回的是fixture对象，不是预期值。
