@sealsystems/test-config-mocha

Jest executable and test configuration for SEAL Systems

Installation

npm install --save-dev @sealsystems/jest

Quick start

Jest is installed as a dependency of @sealsystems/test-config-mocha. So you can call jest from the root directory of your project:

$(npm bin)/jest

Please note:

• In order to install all dependencies directly in the project's node_modules folder, you may need to delete package-lock.json before adding this package.

The package also provides some CLI executables:

• test-run runs Jest

• test-coverage collects coverage data

• test-coverage-check collects coverage data and fails if threshold (80% for all criteria) has not been reached

• test-report collect coverage data and opens the generated HTML page

To use these executables, add some scripts to your package.json:

...
"scripts": {
  "test": "test-run",
  "test:coverage": "test-coverage",
  "test:coverage:check": "test-coverage-check",
  "test:report": "test-report"
}
...

And call them via npm run:

npm run test
npm run test:coverage
npm run test:coverage:check
npm run test:report
