import ( "github.com/cloudfoundry/cli/testhelpers/terminal" ) func TestMyCLI(t *testing.T) { ui := &terminal.FakeUI{} // Use ui to test CLI commands }
func TestMyCLI(t *testing.T) { ui := &terminal.FakeUI{} ui.Say("Hello, world!") }This example uses the `Say` method on the `FakeUI` struct to add output to the fake terminal window. When the test is run, the output "Hello, world!" will be printed. Overall, the `github.com.cloudfoundry.cli.testhelpers.terminal` package library provides tools for testing Go-based command-line applications by simulating user input and output interactions in a fake terminal window.
