Plugin Test

Advanced Code Editor Acceptance Test

Use this skill for release-level verification of advanced-code-block. Keep the bar high: startup under 50 ms, Shiki highlighting working in reading mode and live preview, settings tab available, desktop and mobile paths covered.

Guardrails

• Do not run against a production vault unless the user explicitly asks. Prefer a disposable test vault.
• Do not modify source code or commit while executing this skill. Reports may be written under planning/test-reports/.
• Treat screenshots as evidence, but also inspect DOM/style state. A screenshot alone is not enough when debugging highlight failures.
• Always turn mobile emulation off after mobile checks.
• If any check is skipped, say so in the report.

Pass 0: Scope

1. Read manifest.json, package.json, and relevant recent commits or release notes.
2. Identify changed surfaces since the last tag with git log <last-tag>..HEAD --oneline when a tag exists.
3. Build a short checklist covering startup, settings, reading mode, live preview, inline code, custom themes/languages if touched, BRAT/release payloads if release work changed, and mobile emulation.

Pass 1: Local Gate

Run the repo's own checks first:

rtk bun run check

For targeted changes, also run focused tests before the full gate, for example:

rtk bun test tests/startup-plugin.test.ts tests/render-children.test.ts
rtk bun run typecheck

Judge Pass 1 as failed if formatting, build, lint, tests, or startup benches fail. Record desktop and mobile-emulation startup numbers from bench:startup and bench:startup:mobile.

Pass 2: Runtime Gate

Use the WDIO BDD harness because it creates isolated vaults and checks both desktop and service-booted mobile-emulated paths:

rtk bun run test:bdd

When focusing on horizontal scroll, use:

rtk bun run test:bdd:scroll

The runtime gate must verify:

• Plugin loads without visible runtime errors.
• app.plugins.plugins['advanced-code-block'] exists in the WDIO Obsidian session.
• Settings tab for advanced-code-block can be opened.
• Reading mode renders one Shiki/Expressive Code block per fenced block, with no duplicate original block.
• Live preview applies Shiki token styling to fenced code and inline {lang} code without scrambling positions.
• @mobile scenarios run through wdio.mobile.conf.mts and assert app.isMobile === true.
• Horizontal scroll moves the whole Live Preview code block and preserves native and internal line numbers.

Pass 3: Obsidian CLI Visual Pass

Use this when screenshots or manual visual evidence are needed. First use the obsidian-cli skill. Confirm the focused vault before any destructive command:

rtk obsidian eval code="app.vault.getName()"
rtk obsidian plugin:reload id=advanced-code-block
rtk obsidian dev:errors
rtk obsidian eval code="app.setting.open(); app.setting.openTabById('advanced-code-block')"
rtk obsidian dev:screenshot path=planning/test-reports/<run>/settings.png

For mobile emulation, prefer the official runtime API or CLI equivalent:

rtk obsidian eval code="app.emulateMobile(true)"
rtk obsidian plugin:reload id=advanced-code-block
rtk obsidian dev:screenshot path=planning/test-reports/<run>/mobile-live-preview.png
rtk obsidian eval code="app.emulateMobile(false)"

Inspect selectors:

rtk obsidian dev:dom selector="div.expressive-code" text
rtk obsidian dev:dom selector=".shiki-inline" text
rtk obsidian dev:dom selector=".cm-content [style*='color'], .cm-content [class*='shiki']" text

Report Shape

Write planning/test-reports/<YYYY-MM-DD-HH-MM>/REPORT.md:

# Advanced Code Editor acceptance test

## Scope

- Version: <manifest version>
- Commit: <sha>
- Payload: local dist / release tag / BRAT-style assets

## Pass 1

- bun run check: pass/fail
- startup desktop: <ms>
- startup mobile emulation: <ms>

## Pass 2

- WDIO BDD: pass/fail/skipped
- desktop scenarios: pass/fail
- mobile-emulated scenarios: pass/fail

## Visual Findings

| Surface                   | Verdict   | Evidence       |
| ------------------------- | --------- | -------------- |
| Reading mode fenced block | pass/fail | screenshot/DOM |
| Live preview fenced block | pass/fail | screenshot/DOM |
| Mobile emulation          | pass/fail | screenshot/DOM |

## Recommendation

ship / hold, with reason

Failure Modes

• BRAT installs only main.js, manifest.json, and styles.css; verify that path explicitly.
• Branch manifest.json must match the release tag BRAT should install.
• plugin:reload can report success even when onload threw; always follow with dev:errors.
• Mobile emulation persists; always disable it at the end.
• Obsidian theme colors may be CSS variables by design when using the built-in Obsidian theme. Do not fail solely because token styles use var(--shiki-code*) unless the requested theme should be a bundled Shiki theme.
