Running Tests

Press Cmd + U to run the unit tests for the ExampleApp target inside Xcode.

Or, from the terminal you can run make test.

Viewing Targets

You may run make targets to see a list of Buck targets available to build/test/etc.

Generating an Xcode Project

To generate the project from the terminal, just run make project. You can then run in the simulator or press Cmd + U to run the tests.

You may also use breakpoints, just like normal when using the generated Xcode project.
