Running UI tests from command line

Recently I ran into an interesting problem of writing UI tests. More interesting thing lied ahead when I had to run these tests on the command line. Here are some of the tips and tricks on how to run your UI tests through command line with variable options.

If the same of your workspace is myWorkspace.xcworkspace and the scheme name of UI tests is UITests.scheme, you can run the following command.


xcodebuild -workspace myWorkspace.xcworkspace -scheme "UITests" -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=10.2' test

For iOS Simulator you can give either of following parameters values. You can view the full list on command line with following instruments command.


instruments -s devices

It will list all available devices with supported iOS versions.

If you want to run only specific tests from the given suite, you can mention it too with -only-testing flag. The only thing you have to mention if series of UITest names separated by spaces, following named parameter key -only-testing

Say, you want to execute only UITestAddition and UITestSubtraction tests, you can write like this


xcodebuild -workspace myWorkspace.xcworkspace -scheme "UITests" -only-testing:SampleAppUITests/UITestAddition -only-testing:SampleAppUITests/UITestSubtraction -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=10.2' test

The output from running UI tests might not be the most pleasant thing in the world. You can tidy it a bit with xcpretty flag at the end of command


xcodebuild -workspace myWorkspace.xcworkspace -scheme "UITests" -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=10.2' test | xcpretty

If you want to run UI tests on device as opposed to simulator, you may run


xcodebuild -workspace myWorkspace.xcworkspace -scheme "UITests" -destination 'platform=iOS,name=My iPod touch' test

Going one step forward, if you want to run UI tests on both device and simulator, you can do following:


xcodebuild -workspace myWorkspace.xcworkspace -scheme "UITests" -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 6,OS=10.2' -destination 'platform=iOS,name=My iPod touch' test

This command will run UI tests on specified simulator and device simultaneously.
