Previously, descriptors of the test devices were stored direclty in the mock device files (e.g., "mock_[hid|msc].[h|c]"). This commit splits out the device descriptors to separate files (e.g., "dev_[hid|msc].c") along with getter functions. Users that want to run the tests locally on a different device simply need to update the "dev_[hid|msc].c" file for their device.

Test HCD interrupt pipe URBs
|
|
Purpose:
|
|
- Test that an interrupt pipe can be created
|
|
- URBs can be created and enqueued to the interrupt pipe
|
|
- Interrupt pipe returns HCD_PIPE_EVENT_URB_DONE
|
|
- Test that URBs can be aborted when enqueued
|
|
|
|
Procedure:
|
|
- Setup HCD and wait for connection
|
|
- Allocate default pipe and enumerate the device
|
|
- Setup interrupt pipe and allocate URBs
|
|
- Enqueue URBs, expect HCD_PIPE_EVENT_URB_DONE, and requeue
|
|
- Stop after fixed number of iterations
|
|
- Deallocate URBs
|
|
- Teardown
|
|
|
|
Note: Some mice will NAK until it is moved, so try moving the mouse around if this test case gets stuck.
