根因分析

conftest.py 中的夹具在没有基本情况的情况下递归调用自身，通常是由于循环依赖或夹具设置中的无限循环。

English

A fixture in conftest.py is calling itself recursively without a base case, often due to circular dependency or infinite loop in fixture setup.

generic

解决方案

  1. 85% 成功率 Identify and break the circular dependency by restructuring fixtures. 
    Refactor conftest.py to avoid fixture A calling fixture B that calls fixture A again.
  2. 80% 成功率 Use 'yield' fixtures with proper teardown to avoid recursive setup. 
    Change fixture to use yield instead of return to ensure cleanup breaks recursion.

无效尝试

常见但无效的做法:

  1. Increasing recursion limit with sys.setrecursionlimit 70% 失败

    This only delays the crash; the infinite loop still exists and may exhaust memory.

  2. Removing all fixtures from conftest.py 80% 失败

    Tests that depend on those fixtures will fail with missing fixture errors.
