Json file by source attr

Lazy Carousel use a JSON file to generate automatically a carousel of images:

{
  "items" : [
    {
      "img": "http://res.cloudinary.com/buddahbelly/image/upload/v1423072364/brilliantbritz/angular-js.png",
      "alt" : "Angular JS framework"
    },
    {
      "img": "http://yeoman.io/assets/img/illustration-home-inverted.1f86.png",
      "alt" : "Yeoman!"
    },
    {
      "img": "http://bower.io/img/bower-logo.png",
      "alt" : "I'm a bird, my name is Bower"
    },
    {
      "img": "https://lh5.googleusercontent.com/-mrFw71M_puI/VE5722ZV70I/AAAAAAAABsE/p4DW4sTySLs/s640-no/nodejs-512%5B1%5D.png",
      "alt" : "Node.js"
    },
    {

      "alt" : "Hey, Github is here!"
    },

      "alt" : "slurp! gulp!"
    }
    
  ]
}

Install Dependencies

npm install

We have preconfigured the project with a simple development web server. The simplest way to start this server is:

npm start or node start.js

Now browse to the app at http://localhost:8000/app/index.html.

Testing

There are two kinds of tests in the angular-seed application: Unit tests and End to End tests.

Running Unit Tests

The angular-seed app comes preconfigured with unit tests. These are written in Jasmine, which we run with the Karma Test Runner. We provide a Karma configuration file to run them.

the configuration is found at karma.conf.js
the unit tests are found next to the code they are testing and are named as ..._test.js.

The easiest way to run the unit tests is to use the supplied npm script:

npm test

This script will start the Karma test runner to execute the unit tests. Moreover, Karma will sit and watch the source and test files for changes and then re-run the tests whenever any of them change. This is the recommended strategy; if your unit tests are being run every time you save a file then you receive instant feedback on any changes that break the expected code functionality.

You can also ask Karma to do a single run of the tests and then exit. This is useful if you want to check that a particular version of the code is operating as expected. The project contains a predefined script to do this:

npm run test-single-run

End to end testing

The angular-seed app comes with end-to-end tests, again written in Jasmine. These tests are run with the Protractor End-to-End test runner. It uses native events and has special features for Angular applications.

the configuration is found at e2e-tests/protractor-conf.js
the end-to-end tests are found in e2e-tests/scenarios.js

Protractor simulates interaction with our web app and verifies that the application responds correctly. Therefore, our web server needs to be serving up the application, so that Protractor can interact with it.

npm start

In addition, since Protractor is built upon WebDriver we need to install this. The angular-seed project comes with a predefined script to do this:

npm run update-webdriver

This will download and install the latest version of the stand-alone WebDriver tool.

Once you have ensured that the development web server hosting our application is up and running and WebDriver is updated, you can run the end-to-end tests using the supplied npm script:

npm run protractor

This script will execute the end-to-end tests against the application being hosted on the development server.

Updating Angular

Previously we recommended that you merge in changes to angular-seed into your own fork of the project. Now that the angular framework library code and tools are acquired through package managers (npm and bower) you can use these tools instead to update the dependencies.

You can update the tool dependencies by running:

npm update

This will find the latest versions that match the version ranges specified in the package.json file.

You can update the Angular dependencies by running:

bower update

This will find the latest versions that match the version ranges specified in the bower.json file.
