問題描述

我有大約 700 個測試要執行.當我全部運行它們時，引發了崩潰

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

由于進程崩潰"，儀器運行失敗."檢查設備詳細信息.測試運行失敗:檢測運行失敗由于進程崩潰".

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

經過一段時間的執行，大約 10 分鐘和約 360-370 次執行測試.

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

Logcat 不包含有關此崩潰的任何信息

Logcat doesn't contain any information about this crash

它適用于從 Android Studio 運行，從 cmd(在 PC 和 Mac 上).使用的設備 - Android 4.1.1 上的三星 S3

It is applicable by running from Android Studio, from cmd (on PC and Mac). Device used - Samsung S3 on Android 4.1.1

還要補充一點:在我之前發布的代碼中，不會發生這種崩潰，但我找不到導致崩潰的確切變化.

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.

請幫我解決這個問題，我試圖在兩周內理解它.

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

推薦答案

我不知道你的問題是否仍然存在，但我自己也遇到過這樣的問題.三星設備上的某些 Android 版本存在一個錯誤:它們沒有正確關閉文件描述符，從而導致文件描述符泄漏.創建 1028 個描述符后 - 進程崩潰.

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.

為了避免這種情況，我不得不在我的測試中減少 HandlerThreads 的使用，并在可能的情況下重新使用它們.但更好的解決方案可能是更換設備.

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.
