Use FuseBox to preprocess files in Karma







## Install

With `npm`

```shell

npm install --save-dev karma-fuse-box

```

With `yarn`

```shell

yarn add --dev karma-fuse-box

```

## Usage

**karma.conf.js**

```js

const path = require("path");

module.exports = config => {

  config.set({

    files: [

      // all files ending in "_test"

      { pattern: "test/*_test.js", watched: false },

      { pattern: "test/**/*_test.js", watched: false }

      // each file acts as entry point for the fusebox configuration

    ],

    preprocessors: {

      // add FuseBox as preprocessor

      "test/*_test.js": ["fusebox"],

      "test/**/*_test.js": ["fusebox"]

    },

    fusebox: {

      // FuseBox configuration

      homeDir: path.join(process.cwd(), "test/")

    },

    // for TypeScript

    mime: {

      "text/x-typescript": ["ts", "tsx"]

    }

  });

};

```

## Alternative Usage

This configuration is more performant, but you cannot run single test anymore (only the complete suite).

The above configuration generates a `FuseBox` bundle for each test. For many test cases this can result in many big files.

The alternative configuration creates a single bundle with all test cases.

**karma.conf.js**

```js

files: [

  // only specify one entry point

  // and require all tests in there

  'test/index_test.js'

],

preprocessors: {

  // add fusebox as preprocessor

  'test/index_test.js': [ 'fusebox' ]

},

// additional arithmetic instructions needed

// unlike WebPack FuseBox will not recognize files only by source code

fuseboxInstructions: '+ test/**_test.js',

```

**test/index_test.js**

```js

// use fusebox runtime API to load spec files

FuseBox.import("./**_test");

```

## Options
