describe-loader

Describe-loader

describe-loader auto-magically wrap the body of the describe expression in a describe with the path of the file (__filename).

Install | Getting started

• Install describe-loader npm install --save-dev describe-loader

• First you need to ensure that __filename is set to true otherwise __filename will always be index.js.

// in webpack.config

node: {
  __filename: true
}

• Apply loader for .jsx?$ or whatever extension you have

// in webpack.config

module: {
  preLoaders: [{}],
  loaders: [{}],
  postLoaders: [{
    test: /\.jsx?$/,
    include: /src/,
    exclude: /node_modules/,
    loader: 'describe'
  }]
}

The output

before:

var Component = require('component_name.jsx');
var $ = require('jquery');

describe('First describe', function() {
  describe('Deep describe', function() {
    beforeEach(function() {
      // do something
    });

    it('should be ok', function() {
      expect(1).to.equal(1);
    });
  });
});

after:

var Component = require('component_name.jsx');
var $ = require('jquery');

describe('First describe', function() {
  describe('Path ' + __filename, function() {
    describe('Deep describe', function() {
      beforeEach(function() {
        // do something
      });

      it('should be ok', function() {
        expect(1).to.equal(1);
      });
    });
  });
});
