15 // Overview: |
|
16 // Test the CActiveSchedulerWait class. |
|
17 // API Information: |
|
18 // CActiveSchedulerWait |
|
19 // Details: |
|
20 // - Verify the thread is panicked when one of the following programming errors occurs: |
|
21 // - the scheduler is started twice. |
|
22 // - the scheduler is stopped without starting scheduler. |
|
23 // - the scheduler is started and then stopped twice. |
|
24 // - the CanStopNow method of scheduler is called without starting scheduler. |
|
25 // - Run different combinations of wait, start, async stop, async stop with a callback, |
|
26 // canstopnow and nested calls to start and async stop operations and verify they run |
|
27 // correctly |
|
28 // - Check the heap is not corrupted by all the tests. |
|
29 // Platforms/Drives/Compatibility: |
|
30 // All. |
