Loads your JSON fixtures and provides a simple way to access them in your unit tests.
npm install karma-fixture-loaderIn Unit Testing it's a common practice to have fixture files with a content that serves as replacement for real implementations (e.g a backend, a 3rd party API...).
This little module loads your JSON files and provides a simple way to access them in your unit tests.
Create a folder in your project somewhere. A common place would be test/fixture.
Now open your karma.conf.js (Karma configuration) and add the loader script and the fixture files to the file list:
``
// ...
files: [
// ...
require.resolve('karma-fixture-loader'),
{
// notice the fixture path here
pattern: 'test/fixture/*.json',
watched: true,
served: true,
included: false
}
]
`
Your JSON fixtures are now available in your tests via Ajax.
Now, add another file to your project that will configure the module and load your files:
__Vanilla JS with Jasmine:__
`js
// path to your fixtures
window.fixtures.setPath('text/fixture');
beforeAll(function(done) {
fixtures.load(done);
});
`
__ES6 and Jasmine:__
`js
import { fixtures } from 'karma-fixture-loader';
// path to your fixtures
fixtures.setPath('test/fixture');
beforeAll(done => fixtures.load(done));
export { fixtures }
`
Returns an Object parsed from a file called "filename.json" in your fixture folder
`
var users = fixtures.get('users.json');
If the same fixture above is an array, returns the first item in this array.
`
var bob = fixtures.getFirst('users.json');
