Selenium 1.0 Testing Tools: Beginner's Guide

By: David Burns

Overview of this book

<p>Selenium is a suite of tools to automate web application testing across many platforms. A strong understanding of using Selenium will get you developing tests to ensure the quality of your applications.</p> <p>This book helps you understand and use Selenium to create tests and make sure that what your user expects to do can be done. It will guide you to successfully implement Selenium tests to ensure the quality of your applications.</p> <p>The Selenium Testing Tools Beginner’s guide shows developers and testers how to create automated tests using a browser. You'll be able to create tests using Selenium IDE, Selenium Remote Control and Selenium 2 as well. A chapter is completely dedicated to Selenium 2. We will then see how our tests use element locators such as css, xpath, DOM to find elements on the page.</p> <p>Once all the tests have been created we will have a look at how we can speed up the execution of our tests using Selenium Grid.</p>

Time for action – creating new commands to verify or assert

Imagine that in the previous example you wanted to have the extension method verify the text on the screen instead of having a separate step to do the verification or assertion. This can make tests a lot more compact and possibly easier to read.

We can see this in the next example:

  1. Open your favorite text editor and the user extensions file that you created earlier.

  2. Create a new function called doFireDateAndVerifyText with the following snippet:

    Selenium.prototype.doFireDateAndVerifyText = function(locator,value){
var dates = new Date();
  var day = dates.getDate();
  if (day < 10){
     day = '0' + day;
  }
  month = dates.getMonth() + 1;
  if (month < 10){
     month = '0' + month;
  }
  var year = dates.getFullYear();
  var prettyDay = day + '/' + month + '/' + year;
  this.browserbot.getUserWindow().checkDate(prettyDay);
  
  var lastResult = new CommandResult();
  try{
   var realValue = this.getText(locator);
  
   if (realValue...
