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:

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

On Windows 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:

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):

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

Run Tests in Debug Mode

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