问题描述

我有大约 700 个测试要执行.当我全部运行它们时，引发了崩溃

I have about 700 tests to execute. When I run them all, there raised a crash

由于进程崩溃"，仪器运行失败."检查设备详细信息.测试运行失败:检测运行失败由于进程崩溃".

"Instrumentation run failed due to 'Process crashed.'" Check device logcat for details. Test running failed: Instrumentation run failed due to 'Process crashed.'

经过一段时间的执行，大约 10 分钟和约 360-370 次执行测试.

after some time of execution, about 10 minutes and ~360-370th executed test.

Logcat 不包含有关此崩溃的任何信息

Logcat doesn't contain any information about this crash

还要补充一点:在我之前发布的代码中，不会发生这种崩溃，但我找不到导致崩溃的确切变化.

One more to add: on previous released of my code this crash is not happen, but I can't find what exactly change gave a crash.

请帮我解决这个问题，我试图在两周内理解它.

Please help me with this issue, I'm trying to understand it over two weeks.

推荐答案

我不知道你的问题是否仍然存在，但我自己也遇到过这样的问题.三星设备上的某些 Android 版本存在一个错误:它们没有正确关闭文件描述符，从而导致文件描述符泄漏.创建 1028 个描述符后 - 进程崩溃.

I don't know if the problem is still actual for you, but I have encountered such problem myself. There was a bug in certain Android versions on Samsung devices: they didn't close file descriptors properly thus creating file descriptors leak. After 1028 descriptors are created - the process crashes.

为了避免这种情况，我不得不在我的测试中减少 HandlerThreads 的使用，并在可能的情况下重新使用它们.但更好的解决方案可能是更换设备.

To avoid this I had to cut on the usage of HandlerThreads in my tests, and re-use them where possible. But the better solution would be to change the device, probably.
