即使测试失败，单元测试脚本也会返回退出代码 = 0 [英] Unit test script returns exit code = 0 even if tests fail

问题描述

我的测试脚本如下所示:

My testing script looks as follows:

import os
import sys
from unittest import defaultTestLoader as loader, TextTestRunner

path_to_my_project = os.path.dirname(os.path.abspath(__file__)) + '/../'
sys.path.insert(0, path_to_my_project)

suite = loader.discover('my_project')
runner = TextTestRunner()
runner.run(suite)

如果我运行这个脚本，输出是:

If I run this script, the output is:

$ python3 runtest.py
.....F.....
======================================================================
FAIL: test_insert (fate.test.test_operators.OperatorTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/chiel/Projects/tfate/libs/fate/../fate/test/test_operators.py", line 16, in test_insert
    self.assertEqual(expected, self.session.text[:14])

- Foo import sys$
?               -
+ Foo import sys


----------------------------------------------------------------------
Ran 12 tests in 0.030s

FAILED (failures=1)

退出代码为零:

$ echo $?
0

但是，Python 文档指出默认情况下，main 调用 sys.exit() 并带有一个退出代码，指示测试运行是成功还是失败."

However, the Python documentation states that "By default main calls sys.exit() with an exit code indicating success or failure of the tests run."

我的脚本有什么问题?

推荐答案

代码未使用 unittest.main.您需要使用 TestResult.wasSuccessful 并手动调用 sys.exit.

The code is not using unittest.main. You need to check the result using TestResult.wasSuccessful and call sys.exit manually.

import sys

....

ret = not runner.run(suite).wasSuccessful()
sys.exit(ret)
