// This file is quite similar to integration/main.go. The main difference is that this file is
// run via `go test` whereas the other is run via `test/lazyintegration/main.go` which provides
// a convenient gui wrapper around our integration tests. The `go test` approach is better
// for CI and for running locally in the background to ensure you haven't broken
// anything while making changes. If you want to visually see what's happening when a test is run,
// you'll need to take the other approach
//
// As for this file, to run an integration test, e.g. for test 'commit', go:
// go test pkg/gui/gui_test.go -run /commit
//
// To update a snapshot for an integration test, pass UPDATE_SNAPSHOTS=true
// UPDATE_SNAPSHOTS=true go test pkg/gui/gui_test.go -run /commit
//
// integration tests are run in test/integration/<test_name>/actual and the final test does
// not clean up that directory so you can cd into it to see for yourself what
// happened when a test fails.
//
// To override speed, pass e.g. `SPEED=1` as an env var. Otherwise we start each test
// at a high speed and then drop down to lower speeds upon each failure until finally
// trying at the original playback speed (speed 1). A speed of 2 represents twice the
// original playback speed. Speed may be a decimal.
