The bumpy road to iOS Command-Line builds. A step-by-step guide. (Work in progress)

ios-command-line-tests.md

• Configure a new (shared) Scheme to run tests during the build phase

• Install ios-sim via Homebrew

    brew install ios-sim
  

• Run ios-sim from a script in the test target

    RUN_UNIT_TEST_WITH_IOS_SIM=YES
    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
  

• Add some weird shit to the App to support command-line runs

  When you try to run the tests, you'll see this error:

    Unknown Device Type. Using UIUserInterfaceIdiomPhone based on screen size
    Terminating since there is no workspace.
  

  This can be fixed by adding some code as described in the link above.

• Install Xcode Command Line Tools

• Finally, run from the test via xcodebuild command

    xcodebuild -sdk iphonesimulator -arch i386 -workspace <name of your workspace>.xcworkspace -scheme <name of your test scheme> clean build
  

Additional Resources

Once you are ready to go, you may want to take a look at the following projects:

• gradle-XcodePlugin - Automate your Build from Source Code to Test Flight
• Kiwi - Spec-based Testing

I'm currently using this setup with Xcode 4.5.2. But Apple seems to actively work on making automated testing as difficult as possible and mixes things up a little with every new Xcode release. So be prepared to run into problems, as soon as you dare to install a new version.
