单元测试期间Xcode CI bot错误(Unexpected TestSuiteWillFinish)

我们最近设置了一个带有iOS应用程序的 Xcode bots,以自动构建和测试我正在处理的应用程序.如果我只是构建和分析,构建过程工作正常.如果我将其设置为运行测试,则最终会出现可变数量的错误,这些错误以意外的TestSuiteWillFinish结尾.例如,最近一次运行显示：

Run test suite TimeClockTestCase encountered an error (Unexpected
TestCaseDidFinish) testParseResponseString encountered an error
(Unexpected TestSuiteWillFinish) testGetIntegrationID encountered an
error (Unexpected TestSuiteWillFinish)

之前的那个只有一个错误：

testAddChildObjectTypeTimeClockEvent encountered an error (Unexpected
TestSuiteWillFinish)

无论显示什么错误,集成结果都会显示所有测试都已通过.如果我直接通过Xcode运行测试(而不是在服务器上运行bot),则没有错误并且传递相同数量的测试.

导致这些错误的原因是什么？如何消除它们？
