Use when writing or changing a test for paneline hooks or draw functions.
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
# Write a test
Tests run only with `claude plugin test .` (also part of `npm run check`). They run in a sandbox like the plugin's own: no file system, no network, no process.
## Layout and names
- One file per area: `tests/<area>.test.ts`, or `.test.tsx` when it mounts UI. Shared helpers for draw trees are in `tests/draw-tree.ts`.
- Import from `claude-code/testing`: `describe`, `expect`, `test`, `mock`. Types `Engine`, `Mounted` come from the same module.
- `describe("<area>")`, then tests named `<ID> <what the user sees>`, for example `M3 clicking a server selects it and shows its actions`. IDs are one letter and a number per file.
- Test body: `async ($, on) => { ... }`. `$` is the engine, `on` registers fake engine hooks.
## Build the fake world
Copy the `worldOf(on)` helper from the nearest test file, for example `tests/mcp-pane.test.tsx`. It:
- calls `mock.clock(on, { now })` and `mock.env(on, { HOME: "/h/u" })`;
- answers the engine events the code under test calls, such as `session.usage` and `ui.open`, with fixed data;
- returns a `world` object that records calls (commands run, usage fetches) for assertions.

How to install
mdr add markneonin/paneline/write-test@sha256:41f34fe2412dff69The line at the top of this page pins the label git:20261006.d655100, 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.
