Use this skill whenever writing tests for Bubble Tea (charmbracelet/bubbletea) TUI applications in Go. Triggers include any mention of testing Bubble Tea models, teatest, golden file testing for TUIs, testing tea.Cmd or tea.Msg, snapshot testing terminal output, or writing tests for any Go CLI/TUI that uses the Elm Architecture (Init/Update/View). Also use when the user asks about testing bubbletea components, bubbles, or lipgloss-styled views, or when they need CI-friendly TUI test patterns.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bubble Tea Testing
Write robust, CI-friendly tests for Bubble Tea TUI applications using a three-layer strategy: direct model unit tests, golden file view snapshots, and full-program integration tests via `teatest`.
## Architecture overview
Bubble Tea's Elm Architecture (`Init`, `Update`, `View`) makes TUI apps inherently testable. `Update(msg) -> (model, cmd)` is a pure function of state and message — no terminal, program, or event loop needed for most tests.
**Three-layer strategy:**
| Layer | Coverage | Speed | Tool |
|-------|----------|-------|------|
| 1. Direct model tests | State transitions, commands, view content | ~ms | Standard `testing` |
| 2. Golden file snapshots | Visual regression on `View()` output | ~ms | `golden.RequireEqual` |
| 3. Full integration | End-to-end user flows | ~seconds | `teatest.NewTestModel` |
Target ratio: **80% Layer 1 / 15% Layer 2 / 5% Layer 3**.
---
## Layer 1: Direct model unit tests
### Constructing test messages
Build `tea.Msg` values directly — they are plain Go structs:
```go
// v1
qKey := tea.KeyMsg{Type: tea.KeyRunes, Runes: []rune("q")}
enter := tea.KeyMsg{Type: tea.KeyEnter}
ctrlC := tea.KeyMsg{Type: tea.KeyCtrlC}

How to install
mdr add dimetron/pi-go/bubbletea-testing@sha256:b2020f5cf8076d77The line at the top of this page pins the label git:20260317.b03b37b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
