What Is Selenium:Overiew

Selenium is a browser automation tool.Selenium automates browsers.which is open source Not required any license to use this tool like QTP .To automate web application selenium will be more useful.

Why We go for Selenium:

• For Regression Testing.
• For Smoke and Sanity Testing
• Quick Testing
• To Reduce the Manual Effort
• Time saving
• For Effective testing purpose
• avoiding doing same working again and again.

Reason:

• Before Releasing the product or services we have to Regression Testing To ensure that all are working fine or not.
• Testing The build:Each and every time the development team will the build with new implementations.But Earlier Sprints or  earlier developed things may affect due latest development or code changes.
• So we should not give any guarantee for that functionality will works in all builds.So every build we have do Regression at least for one Release one .
