根因分析

在测试中使用的app实例与dependency_overrides设置的实例不同,或者未在测试后清理覆盖。

English

Using `app.dependency_overrides` on a different app instance than the one under test, or not clearing overrides after.

generic

解决方案

  1. 95% 成功率
    client = TestClient(app)\napp.dependency_overrides[get_db] = fake_db
  2. 93% 成功率
    @pytest.fixture\ndef client():\n    yield TestClient(app)\n    app.dependency_overrides.clear()

无效尝试

常见但无效的做法:

  1. 70% 失败

    If the TestClient uses a different app, overrides never apply.

  2. 80% 失败

    FastAPI resolves via dependency_overrides, not module lookup.
