Before scan

xcodebuild \
  -workspace MyApp.xcworkspace \
  -scheme "MyApp" \
  -sdk iphonesimulator \
  -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1' \
  test

As the output will look like this

you’ll probably want to use something like xcpretty, which will look like this:

set -o pipefail &&
  xcodebuild \
    -workspace MyApp.xcworkspace \
    -scheme "MyApp" \
    -sdk iphonesimulator \
    -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1' \
    test \
  | xcpretty \
    -r "html" \
    -o "tests.html"

With scan

fastlane scan

Why scan?

scan uses the latest APIs and tools to make running tests plain simple and offer a great integration into your existing workflow, like fastlane or Jenkins.

scan Features
🏁 Beautiful inline build output while running the tests
🚠 Sensible defaults: Automatically detect the project, schemes and more
📊 Support for HTML, JSON and JUnit reports
🔎 Xcode duplicated your simulators again? scan will handle this for you
🔗 Works perfectly with fastlane and other tools
🚅 Don’t remember any complicated build commands, just scan
🔧 Easy and dynamic configuration using parameters and environment variables
📢 Beautiful slack notifications of the test results
💾 Store common build settings in a Scanfile
📤 The raw xcodebuild outputs are stored in ~/Library/Logs/scan
💻 Supports both iOS and Mac applications
👱 Automatically switches to the travis formatter when running on Travis
📖 Helps you resolve common test errors like simulator not responding

scan uses a plain xcodebuild command, therefore keeping 100% compatible with xcodebuild. To generate the nice output, scan uses xcpretty. You can always access the raw output in ~/Library/Logs/scan.

Usage

fastlane scan

That’s all you need to run your tests. If you want more control, here are some available parameters:

fastlane scan --workspace "Example.xcworkspace" --scheme "AppName" --device "iPhone 6" --clean

If you need to use a different Xcode install, use [xcodes](https://docs.fastlane.tools/actions/xcodes) or define DEVELOPER_DIR:

DEVELOPER_DIR="/Applications/Xcode6.2.app" scan

To run scan on multiple devices via fastlane, add this to your Fastfile:

scan(
  workspace: "Example.xcworkspace",
  devices: ["iPhone 6s", "iPad Air"]
)

For a list of all available parameters use

fastlane action scan

To access the raw xcodebuild output open ~/Library/Logs/scan

Scanfile

Since you might want to manually trigger the tests but don’t want to specify all the parameters every time, you can store your defaults in a so called Scanfile.

Run fastlane scan init to create a new configuration file. Example:

scheme("Example")
devices(["iPhone 6s", "iPad Air"])

clean(true)

output_types("html")

Automating the whole process

scan works great together with fastlane, which connects all deployment tools into one streamlined workflow.

Using fastlane you can define a configuration like

lane :test do
  scan(scheme: "Example")
end
