根因分析

使用 fixture 设置 HTTP 请求的测试函数期望返回 200 状态码，但由于 URL 错误或资源缺失，端点返回了 404。

English

A test function using a fixture that sets up an HTTP request expects a 200 status code, but the endpoint returns 404 due to incorrect URL or missing resource.

解决方案

  1. 90% 成功率 
    Update the fixture to use the correct URL: `@pytest.fixture
def api_client():
    return Client('http://localhost:8000/api/v2')`
  2. 95% 成功率 
    Verify the endpoint exists by testing manually with curl before running the test suite.

无效尝试

常见但无效的做法:

  1. 90% 失败

    This masks the actual problem; the test still fails to validate the correct behavior, leading to false positives in other scenarios.

  2. 50% 失败

    The issue is not timing-related; the server is running but the endpoint is wrong or missing, so sleeping does not help.
