Testing Elm Programs

elm-program-test provides a convenient API that works with elm-test (opens new window) (including Test.Html) for testing your Elm programs as complete units. Testing your programs at this level provides test coverage that is resilient even to drastic refactorings of your application architecture, and encourages tests that make it clear how end-users and external services will interact with your program.
