Testing Actions Over Time
I’ll show a way to test events scheduled over time, threads and other execution contexts with a
DebugContextCoordinatorthat functions as a basic task scheduler but operates over a simulated version of time so that testing of invocation times and task interaction can be precise and free from changes due to host activity.[…]
Now that libdispatch is replaced by the more flexible
Exec, we can use the flexibility to schedule events with something other than libdispatch.[…]
The advantage with using a
DebugContextandDebugContextCoordinatorto handle timing is that you’re no longer dependent on the actual timing information from the host machine, leading to greater precision and greater reliablility in testing.
