We already have an extensive mirror test (041) which does cover cancelling a mirror job, especially after it has emitted the READY event. However, it does not check what exact events are emitted after block-job-cancel is executed. More importantly, it does not use throttling to ensure that it covers the case of block-job-cancel before READY. It would be possible to add this case to 041, but considering it is already our largest test file, it makes sense to create a new file for these cases.

# This test covers what happens when a mirror block job is cancelled |
||||
|
# in various phases of its existence. |
||||
|
# |
||||
|
# Note that this test only checks the emitted events (i.e. |
||||
|
# BLOCK_JOB_COMPLETED vs. BLOCK_JOB_CANCELLED), it does not compare |
||||
|
# whether the target is in sync with the source when the |
||||
|
# BLOCK_JOB_COMPLETED event occurs. This is covered by other tests |
||||
|
# (such as 041). |
