Testing whether certain elements are visible or not

Question

How do I find out if an element is visible or hidden in testacular (jasmine)?

My DOM looks like:

<div class="span5 value-entry">
    <input type="text" ng-model="query.value" placeholder="Enter value" class="input-large" ng-show="genericInput(criteria.attribute)">
    <select ng-model="query.value" ng-options="entry for entry in filteredValue(criteria.attribute)" class="input-medium" ng-show="!genericInput(criteria.attribute)">
        <option value="">-- Select Value --</option>.
    </select>
</div>

Either the select is shown or the input box, but not both. I wish to check which element is visible (based on some other criteria), but I can't seem to figure out how to get the code working. I have written the following code:

expect(element('.value-entry input').is(':visible')).toBe(true);

But I get an error:

TypeError: Object #<Object> has no method 'is'

How do I check if the input is visible and the select is hidden at the same time (and vice versa)?

EDIT : I wish to add here that this is an end to end test

Answer 1

This behavior has changed in Angular 1.2 because of ng-animate.

The code for ngShow is:

var ngShowDirective = ['$animate', function($animate) {   return function(scope, element, attr) {     scope.$watch(attr.ngShow, function ngShowWatchAction(value){       $animate[toBoolean(value) ? 'removeClass' : 'addClass'](element, 'ng-hide');     });   }; }]; 

Which means that it will add/remove class ng-hide to hide/show the element.

Thus, as an example, the right way to test if the element is hidden would be:

expect(element.find('.value-entry input').hasClass('ng-hide')).toBe(true);

You were close. However, here is how you should test visibility:

expect(element('#some-id:visible').count()).toBe(1); 

Answer 3

Visibility Test

By default, display is set to inline for input, and inline-block for select. Therefore, you can determine if either are currently shown by testing for the existence of the default CSS property.

expect(element('.value-entry input').css('display')).toBe('inline');
expect(element('.value-entry select').css('display')).toBe('inline-block');

To check if either are hidden, replace inline and inline-block with a check for none, which is how ngShow hides an element.

expect(element('.value-entry input').css('display')).toBe('none');
expect(element('.value-entry select').css('display')).toBe('none');
