Test Ordering
by default tests are run in alphabetical order, now there’s a random order option:
Parallel Testing
When targeting the Simulator, Xcode will create several clones of the selected simulator and they will run different tests concurrently (Xcode will create/destroy clones by itself, no action necessary from our side).
The original simulator is not used for testing: it’s being used as a template for the clones
Parallel Testing Tips
Every clone will run one (test) class, therefore have as small classes as possible. If all your tests are in one class, parallel testing is exactly the same as non parallel testing
No performance test in parallel, they should be put in their own (test) bundle
