$controller

- service in module ngMock

A decorator for $controller with additional bindings parameter, useful when testing controllers of directives that use bindToController.

Example

// Directive definition ...

myMod.directive('myDirective', {
  controller: 'MyDirectiveController',
  bindToController: {
    name: '@'
  }
});


// Controller definition ...

myMod.controller('MyDirectiveController', ['$log', function($log) {
  $log.info(this.name);
}]);


// In a test ...

describe('myDirectiveController', function() {
  it('should write the bound name to the log', inject(function($controller, $log) {
    var ctrl = $controller('MyDirectiveController', { /* no locals */ }, { name: 'Clark Kent' });
    expect(ctrl.name).toEqual('Clark Kent');
    expect($log.info.logs).toEqual(['Clark Kent']);
  }));
});

Usage

$controller(constructor, locals, [bindings]);

Arguments

Param Type Details

constructor

Param	Type	Details
constructor	function()string	If called with a function then it's considered to be the controller constructor function. Otherwise it's considered to be a string which is used to retrieve the controller constructor using the following steps: check if a controller with given name is registered via `$controllerProvider` check if evaluating the string on the current scope returns a constructor if $controllerProvider#allowGlobals, check `window[constructor]` on the global `window` object (not recommended) The string can use the `controller as property` syntax, where the controller instance is published as the specified property on the `scope`; the `scope` must be injected into `locals` param for this to work correctly.
locals	Object	Injection locals for Controller.
bindings (optional)	Object	Properties to add to the controller before invoking the constructor. This is used to simulate the `bindToController` feature and simplify certain kinds of tests.

function()string

If called with a function then it's considered to be the controller constructor function. Otherwise it's considered to be a string which is used to retrieve the controller constructor using the following steps:

check if a controller with given name is registered via $controllerProvider
check if evaluating the string on the current scope returns a constructor
if $controllerProvider#allowGlobals, check window[constructor] on the global window object (not recommended)

The string can use the controller as property syntax, where the controller instance is published as the specified property on the scope; the scope must be injected into locals param for this to work correctly.

locals

Object

Injection locals for Controller.

bindings

(optional)

Object

Properties to add to the controller before invoking the constructor. This is used to simulate the bindToController feature and simplify certain kinds of tests.

Returns

Object

Instance of given controller.
