1.1-What is testing?
What is testing?
"Software testing is a way to asses the quality of the software and to reduce the risk of software failures in operation."
Note
ISTQB definition: "Testing is the process consisting of all lifecycle activities (static and dynamic) concerned with planning preparation and evaluation pf a component system and related work products to determine that they satisfy specified requirements for purpose and to detect defects."
A common misconception of testing is that it only consists of running tests, executing the software and checking the results. However, test activities are before and after test execution.
