At a glance

Run unit tests for the Cosmos Explorer project. An agent skill from Azure/cosmos-explorer.

SKILL.md covers Pre-Test: Check Dependencies, Run All Unit Tests, Run a Single Test File and Run Tests in Debug Mode, plus 2 more sections
Calls npm and npx
Check test results

What it does

Run Unit Tests is an agent skill from Azure/cosmos-explorer, published by the product's own GitHub organization. Run unit tests for the Cosmos Explorer project. Use this skill when asked to run tests, check test results, or debug test failures.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Unit testing and Failing and flaky tests. It works with Jest and npm. The repository describes itself as: UI for Azure Cosmos DB. Powers the Azure Portal, https://cosmos.azure.com/, and the Cosmos DB Emulator. The licence is MIT.

When your agent uses it

Asked to run tests
Check test results
Debug test failures

Example prompts

“/run-unit-tests”

Requirements

Node.js
Pre-approved tools (allowed-tools): shell

What it can do on your machine

Read from SKILL.md and the folder at commit 226a7a2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- shell
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.
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.

Context cost

Run Unit Tests loads about 638 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 261 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~37
When it runs · the whole SKILL.md, loaded when a task matches: ~638

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

allowed-tools: shell

Test Skill

Use the following commands to run unit tests for the Cosmos Explorer project.

Pre-Test: Check Dependencies

Before running tests, check whether npm install needs to be run:

bash

if [ ! -d node_modules ] || [ package.json -nt node_modules ] || [ package-lock.json -nt node_modules ]; then
  npm install
fi

On Windows PowerShell:

powershell

if (-not (Test-Path node_modules) -or
    (Get-Item package.json).LastWriteTime -gt (Get-Item node_modules).LastWriteTime -or
    (Get-Item package-lock.json).LastWriteTime -gt (Get-Item node_modules).LastWriteTime) {
    npm install
}

Always run this check before proceeding with any test command.

Run All Unit Tests

Run the full test suite with coverage:

bash

npm test

This clears the coverage/ directory and runs Jest with coverage collection enabled.

Run a Single Test File

Run a specific test file without coverage (faster):

bash

npm run test:file -- path/to/file.test.ts

Run Tests in Debug Mode

Run tests serially (useful for debugging flaky or interdependent tests):

bash

npm run test:debug

Run Tests Matching a Pattern

Run only tests whose names match a pattern:

bash

npx jest --coverage=false --testPathPattern="SomeComponent"

Guidelines

When asked to simply "run tests" or "test", run npm test for the full suite.
When asked to test a specific file or component, use npm run test:file -- <path>.
When debugging test failures, use npm run test:debug to run serially.
Unit test files live adjacent to source files (Foo.test.ts next to Foo.ts in src/).
Tests use Jest with jest-environment-jsdom.
Use @testing-library/react for new component tests. Do not use Enzyme for new tests.
Use Jest built-in mocking, not sinon.js.
Coverage thresholds are enforced globally: branches 25%, functions 24%, lines 28%, statements 28%.
If tests fail, read the error output carefully. Common issues include:
- Snapshot mismatches: Review the diff. If the change is intentional, update snapshots with npx jest --updateSnapshot.
- Mock issues: Ensure mocks are set up correctly and reset between tests.
- Import errors: Check that module name mappings in jest.config.js are correct.
- Type errors in tests: Run npm run compile to check for TypeScript issues.
