Xcode 4.5 Command Line Unit Tests

post_run_script.rb

# Run iOS Unit Tests from the command line with Xcode 4.5 and iOS 6
# Adapted from Scott Thompson at http://stackoverflow.com/a/10823483/1359212
#
# Steps:
# 1. Create a new Xcode Scheme for the Tests target
# 2. Edit the Tests Scheme so that the "Run" checkbox is checked for the Tests target
# 3. Use this script as the Test Target's "Run Script" entry on the "Build Phases" tab
# 4. Run tests from the command line with:
#        xcodebuild -sdk iphonesimulator -scheme 'TestSchemeName' build SL_RUN_UNIT_TESTS=YES
