What is a Test ?
Before anything else lets first understand what it a "Test".
In the Test Management World
In very simple terms, a Test is a sequence of steps coupled with conditions or variables, test inputs and an expected result. It is intended to establish the quality, performance or reliability of a piece of system, i.e., test target.
Usually, every requirement or objective the test target is expected to achieve needs at least one Test.
The success of the Test is determined by comparing expected and actual results.
In Jira
