    <p>I'm currently researching my problem but I thought adding a question here may help as I'm new to AngularJS and even newer to Unit Testing.</p> <p>I have the current directive that works, it users the <code>$watch()</code> function to track a variable, if the variable is not present a default message is provided, for example "Deleted User Value" ...</p> <pre><code>angular.module('myModule') .directive('displayName', function ($transform) { return { restrict: 'A', scope: { displayName: '=' }, link: function (scope, element) { scope.$watch('displayName', function(value){ if(!value) { element.html($transform('users.profile.deletedUser')); } else { element.html(value); } }); } }; }) ; </code></pre> <p>and I have the following unit test (please note that I have amended this on the advice of Maurice) :</p> <pre><code>beforeEach(module('myModule')); beforeEach(inject(function($compile, $rootScope) { $scope = $rootScope; element = angular.element('&lt;div class="name" display-name="name"&gt;&lt;/div&gt;'); $compile(element)($scope); })); it('should display the deleted user name', inject(function() { $scope.displayName = null; element.scope().$apply(); console.log(element); expect(element.html()).toBe('Deleted User Value'); })); </code></pre> <p>However I am getting the following issue: <code>TypeError: Attempted to assign to readonly property</code>. and the <code>console.log</code> is not being outputted, can anyone advise where I am going wrong? Sorry for my stupidity but I am trying to learn unit testing "on the job" and I am still very new to AngularJS</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
