In previous post I showed how to write and run unit tests. Now, I will present how to test DOM manipulation or the wiring of our application. Angular Scenario Runner which simulates user interactions that will help us to do that.
Recall
adverts.html code which we should know to simulate user interaction:
<![CDATA[
<div class="row-fluid">
<div class="span3">
<h4>Adverts</h4>
<div class="ma-left-filter-panel">
<accordion close-others="oneAtATime">
<accordion-group heading="{{brand.name}}" ng-repeat="brand in brands">
<ul ng-repeat="model in brand.models">
<li><a href="" ng-click="addBrandModelFilter(brand, model)">{{model.name}}</a></li>
</ul>
</accordion-group>
</accordion>
</div>
</div>
<div class="span9">
<div class="ma-top-filter-panel">
<h4>Adverts search</h4>
<form>
<div class="row-fluid">
<div class="span4">
<label>Country</label>
<select ng-model="filter.country" ng-options="c.name for c in countries">
<option value=""></option>
</select>
</div>
<div class="span4">
<label>Region</label>
<select ng-model="filter.region" ng-options="r.name for r in filter.country.regions">

ng-minlength="4" ng-maxlength="4" type="number" placeholder="From">
<input ng-model="filter.yearTo" class="input-small" min="1980" max="2013"
ng-minlength="4" ng-maxlength="4" type="number" placeholder="To">

<div class="row-fluid">
<div class="span12">

<a ng-show="isAnyFilter()" href="" ng-click="removeAllFilter()">Remove all</a>

</form>
</div>
<div>
<div class="row-fluid">
<div class="span4">
<h4>Adverts found ({{adverts.length}})</h4>

We should write the simple html page for running unit tests (
runner.html):
<![CDATA[
<html lang="en">
<head>
<title>End2end Test Runner</title>
<meta charset="utf-8">
<script src="../../app/lib/angular/angular-scenario.js" ng-autotest></script>
<script src="scenarios.js"></script>
</head>
<body>
</body>
</html>
]]>
When everything is ready we can start writing tests in
scenarios.js.
Step 1
Navigate web browser to
index.html which route to
adverts.html view:
'use strict';
describe('MotoAds App', function() {
describe('Adverts view', function() {
beforeEach(function() {
browser().navigateTo('../../app/index.html#/');
});
// TEST WILL BE HERE
});
});
]]>
Step 2
We write first E2E test - filtering by brand and model on real data:
it('should filter on brand and model link click', function() {
expect(repeater('.ma-advert-table-row').count()).toBe(29);
element('.accordion-group:eq(0) ul:eq(0) a').click();
expect(repeater('.ma-advert-table-row').count()).toBe(4);
element('.accordion-group:eq(3) ul:eq(0) a').click();
expect(repeater('.ma-advert-table-row').count()).toBe(2);
});
]]>
Step 3
We write second E2E test - filtering by country and region:
it('should filter on country and region select choose', function() {
expect(repeater('.ma-advert-table-row').count()).toBe(29);
select('filter.country').option('Germany');
expect(repeater('.ma-advert-table-row').count()).toBe(20);
select('filter.region').option('Bavaria');
expect(repeater('.ma-advert-table-row').count()).toBe(18);
});
]]>
Step 4
We write third E2E test - filtering by year:
it('should filter on yearFrom and yearTo type', function() {
expect(repeater('.ma-advert-table-row').count()).toBe(29);
input('filter.yearFrom').enter('2010');
expect(repeater('.ma-advert-table-row').count()).toBe(16);
input('filter.yearTo').enter('2011');
expect(repeater('.ma-advert-table-row').count()).toBe(14);
});
]]>
Step 5
We write fourth E2E test - sorting by year:
it('should sort by year', function() {
expect(repeater('.ma-advert-table-row').count()).toBe(29);
select('sortByCol').option("Year");
expect(element('.ma-advert-table-row:eq(0) td:eq(3)').text()).toContain('2005');
expect(element('.ma-advert-table-row:eq(28) td:eq(3)').text()).toContain('2012');
});
]]>
Step 6
We run E2E test by typing in web browser URL
http://localhost:8000/test/e2e/runner.html (motoAds application must be run on the web server). In web browser we should see the same as the screenshot
E2E (end-to-end) tests result.
If you want to run this example on your computer, you can download sources from
GitHub.
Any comment would be highly appreciated.
