broccoli-directory/__tests__/build.test.ts

Broccoli Directory provides familiar map/reduce/filter APIs for working with Broccoli Trees. It allows to chain broccoli tree transformations in the same way that you would chain array operations.

import $d from '../src/index';
import fixturify = require('fixturify');
import tempdirectory = require('tempdirectory');

let dir;
beforeEach(() => {
  dir = $d('__tests__/fixtures/testdir').map(content => `*${content}*`);
});
