Testing and debugging Bubble Tea v2
These examples use Bubble Tea v2.1.0. Return to the main skill for the program loop and command patterns.
Testing
View and Update are plain methods, so unit tests construct messages and
call them. For end to end runs, give the program an io.Reader of
keystrokes, a buffer for output, and a fixed size
(examples/charmed-bubbletea/testing/main_test.go):
// examples/charmed-bubbletea/testing/main_test.go
func TestCursorMovesAndSelects(t *testing.T) {
var m tea.Model = model{items: []string{"a", "b", "c"}}
m, _ = m.Update(tea.KeyPressMsg{Code: 'j', Text: "j"})
m, _ = m.Update(tea.KeyPressMsg{Code: tea.KeyDown})
m, cmd := m.Update(tea.KeyPressMsg{Code: tea.KeyEnter})
if got := m.(model).chosen; got != "c" {
t.Fatalf("chosen = %q, want c", got)
}
if _, ok := cmd().(tea.QuitMsg); !ok {
t.Fatal("expected the returned command to produce a QuitMsg")
}
}
func TestProgramHeadless(t *testing.T) {
in := strings.NewReader("j\r")
var out bytes.Buffer
p := tea.NewProgram(model{items: []string{"a", "b", "c"}},
tea.WithInput(in),
tea.WithOutput(&out),
tea.WithWindowSize(40, 10),
tea.WithoutSignals(),
)
final, err := p.Run()
// ...
}tea.WithColorProfile(colorprofile.Ascii) makes rendered output free of
color codes when you want to compare strings.
Debugging
Standard output belongs to the renderer while the program runs. Log to a file instead:
// excerpt: tea.LogToFile with the standard library logger; charmed-log's tea example uses LogToFileWith
f, err := tea.LogToFile("debug.log", "debug")
if err != nil {
fmt.Fprintln(os.Stderr, err)
os.Exit(1)
}
defer f.Close()
log.Println("this goes to debug.log")Then tail -f debug.log in another terminal. Bubble Tea recovers panics by
default and restores the terminal; pass tea.WithoutCatchPanics() to get a
raw stack trace while developing.
