What is Test Automation?
A process of writing a computer program to do testing that would otherwise need to be done manually
Use of software to control the execution of tests
Two types of test automation:Code-driven testingGraphical user interface testing
3www.mindqonline.com
Advantages of Automation Tests perform precisely the same operations each
time they are run, thereby eliminating human error.
Repeatable: You can test how the software reacts under repeated execution of the same operations.
Reusable :You can reuse tests on different versions of an application, even if the user interface changes.
SPEED :Run tests significantly faster than human users.
Cost Reduction :As the number of resources for regression test are reduced.
Better Quality software:Rapid feedback to developers during the development process as a result of frequent regression testing.

Disadvantages of Automation
Proficiency is required to write the automation test script.
Debugging the test script is major issue. If any error is present in the test script, sometimes it may lead to dadly consequences.
Test maintenance is costly in case of playback methods. Even though a minor changes occurs in the GUI, the test script has to be rewritten.
Maintenance of test data files is difficult, if the test script tests more screens or web-pages.
Short iteration or very tight deadline, there is not enough time to build test automation.

What is Selenium?A set of tools that supports rapid development of
test automation for web-based applications.
Can be recorded and written as HTML
Support for a number of programming languages: Java, C#, Perl, PHP, Python, Ruby
Cross browsers support: IE, Firefox, Opera, Safari and Google Chrome
Cross platform support: Windows, Linux, and Macintosh.

Selenium IDE Selenium IDE (SIDE) is a complete Integrated
Development Environment (IDE) for building Selenium test case.
Firefox add-on that makes it easy to record, edit, and debug tests.
Provides an easy-to-use interface for developing and running individual test cases or entire test suites.
Can be used to generate code to run the tests with Selenium Remote Control (RC).

Selenium IDE Features Record, playback, edit
Intelligent component identification will use object IDs, names, or XPath as needed
Auto complete for all common Selenium commands
Walk through test cases and test suites.
Debug and set breakpoints
Save tests as HTML, or export as other supported programming languages
Support for Selenium user extensions9www.mindqonline.com

Two step process:
Step 1. Check if Firefox is installed
1a. If Firefox is not installed on your machine

Test Case : Login
Test-Case Objective:
Ensure Valid User Login
Expected Result:

“Welcome” 22
Steps :1. In the login textbox
type “lname”. 2. In the password
textbox type “password”.
3. Click “Submit” button
4. Verify that a correct user name is displayed
5. Log outwww.mindqonline.com
Test Script : LoginTest Script Steps:
Login using :
Login Name: lname
Password: password
Click Login button
Highlight “Welcome Admin” text
Right-click and select VerifyTextPresent

Ensure Valid User Login
Steps In the login textbox type
admin. In the password textbox type
password. Click Submit button Verify that a correct user
name is displayed Logout

Running Selenium Automated Test
Make sure the Firefox browser is still open
Go to Selenium IDE and click “Play current test case” button
28www.mindqonline.com
Debugging
Examine the result of the script.
29
Time is needed to validate the login information…
The test must WAIT for the next web page to load before proceeding.
What went wrong?
www.mindqonline.com
Debugging Tips
Open Selenium IDE through Tools menu, otherwise the IDE may freeze and act unpredictably.
Make sure you substitute click command with clickAndWait command wherever needed.
30www.mindqonline.com
EditingEditing to add wait time to the script Click the 3rd to last row where ClickA
command is located Modify the command field
Replace “click” with “clickAndWait” command
Re-play the test…
31www.mindqonline.com
Note:
One Firefox browser window must be open.
Multiple browser windows will confuse Selenium.
Play back every automated test to ensure
expected behavior.
Keep playback in slow mode when debugging.
Placing Browser window and Selenium IDE
windows side by side is a convenient way of
tracking test execution step by step.
