Mocha executable and test configuration for SEAL Systems
npm install @sealsystems/mochaMocha executable and test configuration for SEAL Systems
``bash`
npm install --save-dev @sealsystems/mocha
Mocha is installed as a dependency of @sealsystems/mocha. So you can call mocha from the root directory of your project:
`shell`
$(npm bin)/mocha
The package also provides some CLI executables:
- test-run runs Mocha
- test-coverage collects coverage data via nyc (which is also installed as a dependency)
- 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
Please note:
- Our standard assert library assertthat is also a dependency of this package. So you do not need to include it in your project's package.json.
- 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.
- Mocha runs with the following settings:
`
test/*/Test.js
--async-only
--bail
--color
--exit
--recursive
--ui tdd
To use these executables, add some scripts to your package.json:
`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:
`shell`
npm run test
npm run test:coverage
npm run test:coverage:check
npm run test:report
The commands evaluate command line parameters from package.json. All parameters prefixed with -mocha are passed to mocha without the prefix. All parameters prefixed with -ny are passed to nyc without the prefix.
Example:
`json`
"scripts": {
"test": "test-run -mocha--max-old-space-size=2500 -nyc--check-coverage"
}
The above example runs mocha with the extra parameter --max-old-space-size=2500 and nyc with the extra parameter --check-coverage`.
