Before going further with Selenium Tutorial, let us first understand some of the key concepts associated with Automation testing of an application.

• Each software development group need to carry out several tests before launching the final product into the market.
• Manual Test engineers seek to catch the fault or bugs before the product released in the market, yet delivered software always has defects. And there is a possibility that the final software product is left with a defect or unable to meet the customer requirement, even the manual test engineer do their best.
• Automation testing is the best way to increase the effectiveness, efficiency, and coverage of Software testing.
• Automation testing uses particular tools to automate manual design test cases without any human interference. These testing tools can access the test data, controls the execution of tests, and compares the actual result against the expected result.

It has both functional and non-functional tests on an application.

Functional Automation Testing

e.g.-: Repetitive Regression tests are automated.

Non-functional Automation Testing

To automate the non-functional performance test cases.
