This is the last tutorial in our Selenium online training series of 30+ comprehensive tutorials. I hope you all enjoyed these tutorials and started learning from it.

1. What is Automation Testing and why we need to go for automation testing

Automation testing is the process of doing testing without any manual intervention. We automate manual test cases using any of the automation tools with any of one programming language.
Why Automation:
• To Save time
• To save money
• Reusable ( we can ran same test cases any number of times like regression testing)
• Error prone human behavior

2. Explain me types of automation testing

We have two types of automation testing

  • Functional Automation: Here automate only functional test cases which basically checks for functionality of application. There are so many tools available for functional automation like QTP, Selenium, VSTS etc..
  • Non-Functional automation (performance testing): As name says we are not checking for functionality but check for performance of the application with respect to response time. Let’s take an example of Gmail application, user enters user id and password and clicks on Login button here we check how much time Gmail is taking to provide response to the user. There are so many tools available for Non-functional automation like Load Runner, JMETER, Silk Performer etc..In Non-Functional OR Performance testing we do below types of testing through automation
  • Load Testing

  • When we have a scope for regression testing
  • When application is stable
  • When no frequent changes to application

Futures of Selenium:

  • It’s Open source functional automation tool and allows to automate functional test cases
  • Selenium tool allows to automate only web based applications
  • Selenium tool supports compatibility testing like you automate test cases and execute them in any browsers like Chrome, IE etc..
  • We can run test cases any of the operating systems like Windows, Android, IOS, MAC etc…
