run-jasmine-browser

A tool that makes it really easy to run your Jasmine tests in a browser.

It doesn't require any extra setup on your part, and you are not required to be using Gulp or Webpack or even Babel in your project.

Prerequisites

You should have node and either yarn or npm installed, and you should have some tests written with Jasmine.

Usage

First, install it:

yarn add -D run-jasmine-browser
# or
npm i run-jasmine-browser --save-dev

Then, import it and start up the test server with one function call!

For example, in run-tests.js:

const runTests = require('run-jasmine-browser');

// with default options:
runTests();

// or, with options:
runTests({ testFiles: 'tests/**/*.test.js' });

Then, you would run node run-tests.js to start up the Jasmine server.

Better yet, put it in an NPM script in your package.json:

  "scripts": {
    "test": "node run-tests.js
  }

Then, it would just be yarn test or npm test to start up the test server.

Options

As shown above, you can pass an options object to configure the way the tests are run. Here are the options:

testFiles

Pattern to use to find test files that Jasmine will run.

default: spec/**/*_spec.js

babelOptions

Options to pass directly to Babel, which will transpile your code before running the tests.

default: Transpiles using babel-preset-env and babel-preset-react. If you're writing ES6 and/or React code with JSX, there's a good chance you won't need to specify anything here.
