根因分析

断言重写被禁用（通过 --assert=plain、PYTHONDONTWRITEBYTECODE 或插件冲突），pytest 无法内省产生 False 的子表达式，只打印原始 assert。

English

Assertion rewriting was disabled (via --assert=plain, PYTHONDONTWRITEBYTECODE, or a plugin conflict), so pytest cannot introspect the sub-expression that produced False and prints only the raw assert.

generic

解决方案

  1. 90% 成功率 
    # pytest.ini
[pytest]
addopts = --assert=rewrite
# ensure no PYTHONDONTWRITEBYTECODE=1 in env
  2. 85% 成功率 
    # conftest.py
import pytest
pytest.register_assert_rewrite('tests.test_api')

无效尝试

常见但无效的做法:

  1. 80% 失败

    -s disables output capture, not assertion rewriting; the introspection message remains absent.

  2. 60% 失败

    This defeats the purpose of pytest's introspection and pollutes test output with manual prints.
