PhpUnit随机卡住60秒

Question

有一个带有测试套件的Laravel应用程序，可以在大约3分钟内完全运行。

大约2分钟左右，测试冻结约60094ms。每次它都是不同的测试，因此它似乎与任何特定的测试都不相关。

所有测试都没有失败，只是经历了奇怪的延迟。 是什么原因导致PhpUnit延迟60秒？

You should really fix these slow tests (>200ms)...
 1. 60094ms to run Tests\Feature\Superadmin\BusinessActivityTest:testDestroyBusinessActivityProductionProcess
 2. 3357ms to run Tests\Feature\AccessTokenTest:testOauthToken
 3. 1124ms to run Tests\Feature\Superadmin\ArticleTest:testUpdateArticleForAdmin
 4. 969ms to run Tests\Feature\VtaDocumentTest:testUploadVehiclesFileHappyPathWithFilePDF
 5. 737ms to run Tests\Feature\VtaDocumentTest:testUploadCertificateFilePDF
...and there are 22 more above your threshold hidden from view

关闭Internet可以避免此问题。

在Print PHP Call Stack的帮助下调试并获取卡住进程的堆栈痕迹后，发现线程被卡在MixPanel代码中。

此外，在MixPanel中创建新用户的事件导致事件被发送。

现在测试已与MixPanel正确分离，不再有突然的延迟。
