    <p>In angular js unit test, I wanted to set xhr response to each test(in "it" method"), not in beforeEach method, but it seems not working.?</p> <p>This works</p> <pre><code>describe('ExampleListCtrl', function(){ var $scope, $httpBackend; beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) { $httpBackend = _$httpBackend_; $httpBackend.expectGET('examples').respond([]); // &lt;--- THIS ONE $controller(ExampleListCtrl, {$scope: $scope = $rootScope.$new()}); })); it('should create "examples" with 0 example fetched', function() { expect($scope.examples).toBeUndefined(); $httpBackend.flush(); expect($scope.examples).toEqual([]); }); }); </code></pre> <p>result</p> <pre><code>Executed 8 of 8 SUCCESS (0.366 secs / 0.043 secs) </code></pre> <p>But this fails with error when I move expectGet method to each method. I don't know why.</p> <pre><code>describe('ExampleListCtrl', function(){ var $scope, $httpBackend; beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) { $httpBackend = _$httpBackend_; $controller(ExampleListCtrl, {$scope: $scope = $rootScope.$new()}); })); it('should create "examples" with 0 example fetched', function() { $httpBackend.expectGET('examples').respond([]); // &lt;--- MOVED TO HERE expect($scope.examples).toBeUndefined(); $httpBackend.flush(); expect($scope.examples).toEqual([]); }); }); </code></pre> <p>Here is the error</p> <pre><code>.... at /Users/me/app/test/unit/controllers/ExampleListCtrlSpec.js:3:1 Error: No pending request to flush at Error (&lt;anonymous&gt;) at Function.$httpBackend.flush (/Users/me/app/test/lib/angular/angular-mocks.js:1171:34) at null.&lt;anonymous&gt; (/Users/me/app/test/unit/controllers/ExampleListCtrlSpec.js:14:18) </code></pre> <p>---- Edited ----</p> <p>Following the advice below, I have moved the controller out of beforeEach, and changed test like this, so that I can test $httpBackend.expectGET more than once.</p> <pre><code>describe('ExampleListCtrl', function(){ var $scope, $rootScope, $httpBackend; beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) { $httpBackend = _$httpBackend_; controller = $controller; $scope = $rootScope.$new(); })); it('should create "examples" model with 0 example fetched from xhr', function() { $httpBackend.expectGET('examples').respond([]); controller(ExampleListCtrl, {$scope: $scope}); $httpBackend.flush(); expect($scope.examples).toEqual([]); }); }); </code></pre>

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).
