1379911 - Device Reset Testing.

Status: NEW

Description

[Vincent Liu[:vliu]]

This bug was filed intending to implement test cases for device reset. Basically this idea was raised when we found a way to trigger device removed event manually. in [1], the session *Testing Device Removed Handling* mentioned how it did. Based on above, it would be better if we can have test cases to hook up dxcap with animation or video cases.

There were some known issues to note.

1. To run dxcap, the execution shell need to have administrator access.
2. The whole windows operating system was easily to crash if dxcap was run too much frquently.

I am looking into the code in crashtest framework. Currently my idea would be.

1. a parameter in test case in crashtests.list to specifiy which test case will run device test testing.
2. Test cases was considered to cover video/animation.

At this moment I don't rule out using other known test cases to do this. I just start with crash test.

The first version of WIP was attached to record. In this WIP, we can run dxCap.exe in specific crash test if it was defined by the keyword |device-reset| in crashtests.list. I also wrote two use cases for animation/video. It seems it still have problems for running animation/video, so I still working on it.

Another WIP was attached to attempt run dxCap on try server. See [1] for detail.

From [1], when test case tried to access dxCap to run, it always returns NS_ERROR_FILE_NOT_FOUND. It could be incorrect path or doesn't have this execution file.
