Usage:
	See https://github.com/jesseduffield/lazygit/tree/master/pkg/integration/README.md

	CLI mode:
		> go run cmd/integration_test/main.go cli [--slow] [--sandbox] <test1> <test2> ...
	If you pass no test names, it runs all tests
	Accepted environment variables:
	INPUT_DELAY (e.g. 200): the number of milliseconds to wait between keypresses or mouse clicks

	TUI mode:
		> go run cmd/integration_test/main.go tui
	This will open up a terminal UI where you can run tests

	Help:
		> go run cmd/integration_test/main.go help
