Stewart Gleadow posted this a while ago, but I’ve recieved so many questions in
the last couple weeks about how to run a unit test bundle for iOS from the
command line that I’m linking here. Stew set up a sample project that
uses some scripts to do the same kind of magic that Xcode does to inject the
unit test bundle into the simulator. Follow the instructions to learn more.
Everything is there for you to dissect how to do it yourself.
Note, you’ll need to install WaxSim to launch the simulator from Stew’s
scripts, and my fork is a stable version that I know works.
