Cometchat React V7 Testing

What it does

When your agent uses it

• Tasks that involve Unit testing
• Tasks that involve End-to-end testing

Example prompts

• “test my cometchat react app”
• “mock cometchat in jest/vitest”
• “unit test chat component”
• “/cometchat-react-v7-testing”

Requirements

• Compatibility (from SKILL.md): @cometchat/chat-uikit-react ^7 (7.1.x–7.2.x verified); React 18–19; Vitest / Jest / React Testing Library / Playwright

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Synchronous assertions before init resolves — flaky; use findBy*/waitFor.
2. 2Asserting on kit DOM classes — they change across versions; assert your own markup + roles.
3. 3A real login in unit tests — mock CometChatUIKit; never ship a test Auth Key to prod env files.
4. 4StrictMode double-invoke — mocks must be idempotent (return the same resolved user), mirroring the app's in-flight guard.

What it can do on your machine

Read from SKILL.md and the folder at commit 911b108. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  @cometchat/chat-uikit-react ^7 (7.1.x–7.2.x verified); React 18–19; Vitest / Jest / React Testing Library / Playwright

  From compatibility in the SKILL.md frontmatter.

Context cost

Cometchat React V7 Testing loads about 1.1k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 482 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~93

When it runs · the whole SKILL.md, loaded when a task matches

~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Test a React app that embeds CometChat v7 — what to mock vs exercise for real, rendering kit components under a test provider, waiting out the async init→login gate, and a lean E2E smoke. Triggers: 'test my cometchat react app', 'mock cometchat in jest/vitest', 'unit test chat component', 'playwright test for chat', 'how do I test cometchat'.
