Advanced Usage

Workflow

HttpBackend workflow is quite simple:

• On browser.get()` a mock module is injected to your angularjs application
• On when*or when you call manually backend.sync(), fixtures is synchronised with your angularjs app.

Increase perfomance

For perfomance issue you can disable auto sync:

    var backend = new HttpBackend(brower, {autoSync: false});
 
    //Then you should manually call sync function
    backend.whenGET(/results/).respond('raoul');
    backend.whenGET(/responses/).respond('raoul');
    backend.sync();
 

Httpbackend Methods
