即使测试失败，单元测试脚本也会返回退出代码 = 0
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.....

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?
答
代码未使用 unittest.main.您需要使用 TestResult.wasSuccessful检查结果> 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)
