plan for integration tests

Integration tests are expected to be heavyweight and test broad areas of a use case. We likely wouldn't have more than 1-2 dozen of them.

startup

• start a Dart VM or a Flutter app on a sample app
• connect to it via a service protocol connection
• start a chrome process
• connect to it via a chrome debug protocol connection
• start a web serve serving a debug build of the devtools app
• switch the chrome tab page to the devtools app w/ the port of the running dart/flutter app
• wait for app initialization

testing

• interact with devtools by invoking methods on objects registered globally
• verify expected behavior by invoking methods, or listening to events written to the browser's console

teardown

• tear down chrome
• tear down the web server
• tear down the running Dart/Flutter app
