amplify-ui-test-sample

Demonstrates Amplify running with UITests

Setup

• pod install
• amplify init
• amplify add auth

This will create an amplifyconfiguration.json file in the root of your project folder. The Xcode project is already set up to reference it.

Running the example test

• Launch Xcode and open the amplify-ui-test-sample.xcworkspace file, not the Project file
• Run the UI tests by hitting "Cmd-U" or selecting Product > Test from the Xcode menu
• Note the UI behavior:
  • Simulator launches the app
  • The label reads "(not started)"
  • The test taps a button
  • Behind the scenes the app invokes Amplify.Auth.fetchAuthSession()
  • The UI view updates the label to be "Signed out"

Proving that the test references amplifyconfiguration.json

• Locally edit amplifyconfiguration.json to remove all content. I use just an empty object: {}
• Re-run the test
• The app crashes as expected with a message like Fatal error: 'try!' expression unexpectedly raised an error: PluginError: Unable to decode configuration
• Restore the content of amplifyconfiguration.json
• Re-run the test
• Test passes as expected
