Xcode 4.5 command line unit testing

Also there's little hack that can help to run command-line tests on iOS6.0 simulator SDK

I'm Using Cedar and this tweak helped me :

First, you need to update your main file a little:

  // Faking up that workspace port
  CFMessagePortCreateLocal(NULL, (CFStringRef) @"PurpleWorkspacePort", NULL, NULL,NULL);
  return UIApplicationMain(argc, argv, nil, @"CedarApplicationDelegate");

Second, you need to add category to UIWindow:

@implementation UIWindow (Private)
- (void)_createContext {
   // Doing nothing here. Just for crash avoidance
}
@end

Cedar Unittest will run fine, with some runtime warnings, but, at least they'll be able to run :)

Just thought I should also share what I did for a solution to this issue. I followed the solution outlined in https://stackoverflow.com/a/10823483/666943 but converted the ruby script to shell. At the end I basically installed ios-sim via homebrew and replace the Run Script in the Build Phases of my Test target with the following:

if [ "$RUN_UNIT_TEST_WITH_IOS_SIM" = "YES" ]; then
    test_bundle_path="$BUILT_PRODUCTS_DIR/$PRODUCT_NAME.$WRAPPER_EXTENSION"
    ios-sim launch "$(dirname "$TEST_HOST")" --setenv DYLD_INSERT_LIBRARIES=/../../Library/PrivateFrameworks/IDEBundleInjection.framework/IDEBundleInjection --setenv XCInjectBundle="$test_bundle_path" --setenv XCInjectBundleInto="$TEST_HOST" --args -SenTest All "$test_bundle_path"
    echo "Finished running tests with ios-sim"
else
    "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests"
fi

To start the test now I pass in the argument RUN_UNIT_TEST_WITH_IOS_SIM=YES e.g.

xcodebuild -workspace MyApp.xcworkspace -scheme MyAppTests -sdk iphonesimulator -configuration Debug clean build RUN_UNIT_TEST_WITH_IOS_SIM=YES

xcodebuild -project ${PROJECT_PATH}/${PROJECT_NAME}.xcodeproj \ -scheme ${TEST_SCHEME} \ -configuration Debug \ -sdk iphonesimulator5.1 \ clean build \ TEST_AFTER_BUILD=YES

Setting the iphonesimulator to version 5.1 seems to solve the problem. There are radar bugs filled upon this issue.

This article also mention a good solution to follow:

I noticed this issue in the beta versions of Xcode 4.5 / iOS 6. I've been working on a standalone unit tests runner to work around this problem. It works by compiling your unit test bundle, then compiling a version of your app that automatically runs the unit tests in a simulator environment.

The tool is by no means complete, but enough people seem to be having this issue that I'm releasing the tool as is for now. Please fork or comment so I can improve the tool.
