We will now turn our attention to testing the Track class. We will focus specifically on the different states a Track class can have: STOPPED, PLAYING, and RECORDING. For each one of these states, we want to make sure that adding SoundEvents works only if we are in the proper state (RECORDING).
To do so, we could write the following test functions:
testAddSoundEvent(): This function puts theTrackin theSTOPPEDstate, callstrack.addSoundEvent(0), and checkstrack.soundEvents().size == 0testAddSoundEvent(): This function puts theTrackin thePLAYINGstate, callstrack.addSoundEvent(0),and checkstrack.soundEvents().size == 0testAddSoundEvent(): This function puts theTrackin theRECORDINGstate, callstrack.addSoundEvent(0), and checkstrack.soundEvents().size == 1
As you can see, the logic is the same, we simply change the inputs and the desired outputs. To factorize this, Qt Test provides another module: datasets.
A dataset can be seen as a two-dimensional...
