我在 Eclipse 中创建了一个 Android 项目，并成功获得了包含线路和突变覆盖率的 Pit Mutation 覆盖率报告，同时我删除了“ Extend Activity ”和“ onCreate() ”。但如果我试图覆盖 Android Activity 及其生命周期 Pit Mutation Test 会给我错误。

Exception in thread "main" org.pitest.help.PitHelpError: All tests did not pass without mutation when calculating line coverage. Mutation testing requires a green suite.See http://pitest.org for more details.

发生这种情况是因为您的一项测试在被 PITest 突变后失败。如果您向上滚动日志，您将看到测试是什么，例如：

2:30:13 PM PIT >> WARNING : Description [testClass=com.foo.BarTest, name=foo(com.foo.BarTest)] did not pass without mutation.
