pytest 报告太多断言失败 [英] pytest reports too much on assert failures

问题描述

pytest 有没有办法只输出一行断言错误?

Is there a way for pytest to only output a single line assert errors?

当你有带有断言的模块时会出现这个问题，如果这些断言失败，它会转储整个断言失败的函数.

This problem arises when you have modules with asserts, If those asserts fails, it dumps the entire function that failed the asserts.

> assert r.status_code == 200, f"{idtest.tools.now()} wrong status code {r.status_code}: resp:{r.text}"
E AssertionError: 2019-06-11 12:41:17.239128 wrong status code 500: resp:{"timestamp":"2019-06-11T10:41:17.187+0000","status":500,"error":"Internal Server Error","message":"The user was not found","path":"/mid/business"}

在这种情况下， idtest.testapi.midbusiness() 完全显示在 pytest 输出中.

In this case the idtest.testapi.midbusiness() is shown entirely in the pytest output.

推荐答案

调整traceback打印模式(--tb):

Adjust the traceback print mode (--tb):

$ pytest --help
  --tb=style            traceback print mode (auto/long/short/line/native/no).

例如pytest --tb=no 根本不会打印任何痕迹.

E.g. pytest --tb=no will not print any trace at all.
