Testing

Testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test.Test techniques include the process of executing a program or application with the intent of finding failures, and verifying that the software product is fit for use.

What is Testing?

Testing is the process of executing a program with the aim of finding errors. To make our software perform well it should be error-free. If testing is done successfully it will remove all the errors from the software.

Why is it important?

If anything, software testing is the more cost-effective approach of handling software applications. Testing alleviates the need for a constant cycle of upgrades and fixes, as software testers identify bugs and errors before any such problems can arise.

Testing is essential because we all make mistakes. Some of those mistakes are not important, but some are expensive or could be life-threatening. We have to test everything that we produce because things can go wrong; humans can make mistakes at any time.
