在 Python 代码上运行突变测试时出错：AttributeError：“MutationTestRunnerThread”对象没有属性“isAlive”

Question

我正在使用Mut.py 进行 Python 编程变异测试。单元测试通过，当我使用命令在命令行上运行 Mutation 测试时，我收到这样的错误。

C:\Users\pc\Desktop\My_Projects\Calculator01>mut.py --target simpleCalculator.py --unit-test test_simpleCalculator.py --runner pytest --coverage
Traceback (most recent call last):

    test_runner.terminate()
  File "c:\users\pc\appdata\local\programs\python\python39\lib\site-packages\mutpy\utils.py", line 357, in terminate
    if self.isAlive():
**AttributeError: 'MutationTestRunnerThread' object has no attribute 'isAlive'**

谁能帮忙？

我最近遇到了同样的问题，这里有一个对我有用的快速修复：

• 打开错误消息中显示的 utils.py
• 转到错误消息中显示的“if self.isAlive():”行
• 进行以下更改： if self.isAlive(): 变成 if self.is_alive():

我的电脑在 Windows 10 上运行 python 3.9.0，mutpy 0.6.1。
