Jasmine Error when trying to set up controller object - angularjs

Question

This is the actual error message that I receive:
Uncaught Error: [$injector:unpr] Unknown provider: formsProvider <- forms <- SignupAcclaimController
this is at the start of my test file:
describe("SignUp", function() {
describe("SignupAcclaimController", function () {
beforeEach(module('CL.SignUp'));
var controller, SignupService, $state, scope, identity;
beforeEach(inject(function (_$controller_, _$state_, _SignupService_, _$rootScope_, _identity_) {
$state = _$state_;
scope = _$rootScope_.$new();
SignupService = _SignupService_;
identity = _identity_;
controller = _$controller_('SignupAcclaimController', {
$state: $state,
SignupService: SignupService,
identity: _identity_,
detailsForm: mocks.form
});
}));........
The error occurs when trying to set controller. mocks.form has been declared above this code.
The actual controller is:
(function() {
'use strict';
angular.module('CL.SignUp')
.controller('SignupAcclaimController', SignupAcclaimController);
SignupAcclaimController.$inject = ['$window', '$state', '$log', 'SignupService', 'identity', 'detailsForm', 'forms', '$rootScope', '$scope', '$timeout'];
function SignupAcclaimController($window, $state, $log, SignupService, identity, detailsForm, forms, $rootScope, $scope, $timeout) {
var vm = this, ........
If I change the injector functions signature to be the same as the method signature of the actual controller then expand the controller = to be
controller = _$controller_('SignupAcclaimController', {
$window: _$window_,
$state: $state,
$log: $log,
SignupService: SignupService,
identity: _identity_,
detailsForm: mocks.form,
forms: _forms_,
$scope: scope,
$rootScope: _$rootScope_,
$timeout: _$timeout_
then the error changes to :
Uncaught Error: [$injector:unpr] Unknown provider: formsProvider <- forms
