Automation Testing..

Test Cases to Automate
  • Test cases to be automated can be selected using the following criterion to increase the automation ROI
    • High Risk - Business Critical test cases
    • Test cases that are executed repeatedly
    • Test Cases that are very tedious or difficult to perform manually
    • Test Cases which are time consuming
    The following category of test cases are not suitable for automation:
    • Test Cases that are newly designed and not executed manually  atleast once
    • Test Cases for which the requirements are changing frequently
    • Test cases which are executed on ad-hoc basis.
    About Automated Testing
    Manual testing is performed by a human sitting in front of a computer carefully executing the test steps. Automation Testing means using an automation tool to execute your test case suite.   The automation software can also enter test data into the System Under Test ,  compare  expected and actual  results and generate detailed test  reports.
    Test Automation demands considerable investments of money and resources. Successive development cycles will require execution of same test suite repeatedly.
    Automated testing is important due to following reasons: 

    • Manual Testing of all work flows, all fields , all negatice scenarios is time taking and costly.
    • Automation does not require Human intervention. You can run automated test unattended (overnight)
    • Automation increases  speed of test execution
    • Automation helps increase  Test Coverage

    The following category of test cases are not suitable for automation:
    • Test Cases that are newly designed and not executed manually  atleast once
    • Test Cases for which the requirements are changing frequently
    • Test cases which are executed on ad-hoc basis

    • Define the scope of Automation


  • Scope of automation is the area of your Application Under Test which will be automated. Following points help determine scope:
    • Feature that are important for the business
    • Scenarios which have large amount of data
    • Common functionalities across applications
    • Technical feasibility
    • Extent to which business components are reused
    • Complexity of test cases
    • Ability to use the same test cases for cross browser testing

  • Test Execution process

  • Automation Scripts are executed during this phase. The scripts need input test data before there are set to run. Once executed they provide detailed test reports.  
    Execution can be performed using the automation tool directly or through the Test Management tool which will invoke the automation tool.


    Example: Quality center is the Test Management tool which in turn it will invoke QTP for execution of automation scripts. Scripts can be executed in a single machine or a group of  machines. The execution can be done during night , to save time.

    How to Choose an Automation Tool? 

    • Selecting the right tool can be a tricky task. Following criterion will help you select the best tool for your requirement-

      • Environment Support
      • Ease of use
      • Testing of Database
      • Object identification
      • Image Testing
      • Error Recovery Testing
      • Scripting Language Used
      • Support for various types of test – including functional, test management, mobile, etc…
      • Support for multiple testing frameworks
      • Easy to debug the automation software scripts
      • Ability to recognize objects in any environment
      • Extensive test reports and results
      • Minimize training cost of selected tools 

      Benefits of automated testing

       Following are benefits of automated testing:

        • 70% faster than the manual testing
        • Wider test coverage of application features
        • Reliable in results
        • Ensure Consistency
        • Saves Time and Cost
        • Improves accuracy
        • Human Intervention is not required while execution
        • Increases Efficiency
        • Better speed in executing tests
        • Re-usable test scripts
        • Test Frequently and thoroughly
        • More  cycle of execution can be achieved through automation 
        • Early time to market

It has started turning out a great page for testing. Feeling stuck to it now.
