Cometchat Angular V5 Testing

What it does

When your agent uses it

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

Example prompts

• “write tests for my chat”
• “mock cometchat in jest”
• “testbed cometchat”
• “/cometchat-angular-v5-testing”

Requirements

• Compatibility (from SKILL.md): @cometchat/chat-uikit-angular ^5 (5.1.0–5.2.0 verified); Angular 17-21; Jest / Karma / Vitest / Playwright

Workflow steps

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

1. 1Unmocked CometChat in unit tests → hangs, flakes, offline failures.
2. 2Mocking the whole module without requireActual → your own wiring never runs.
3. 3Asserting kit DOM internals → breaks on every kit release.
4. 4Tests against a production app → real users, real data.
5. 5No zero-height assertion in E2E → the most common visual break goes unnoticed.
6. 6No teardown in tests → leaked listeners bleed across specs.

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-angular ^5 (5.1.0–5.2.0 verified); Angular 17-21; Jest / Karma / Vitest / Playwright

  From compatibility in the SKILL.md frontmatter.

Context cost

Cometchat Angular V5 Testing loads about 1.6k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 566 words of instructions outside code blocks.

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

~89

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

~1.6k

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 an Angular app that embeds CometChat — what to mock vs exercise for real, TestBed setup for standalone kit components, avoiding real network in unit tests, and a two-account manual pass for realtime. Triggers: 'write tests for my chat', 'mock cometchat in jest', 'testbed cometchat', 'my tests hang', 'e2e test the chat'.
