What is testing?

Any ideas?

"Testing means checking it works"

Source: a younger, less experienced me.

Software testing can be stated as the process of validating and verifying that a software program/application/product:

1. meets the requirements that guided its design and development;

2. works as expected; and

3. can be implemented with the same characteristics.
