In order to understand the testing methodology, we need to understand the workbench concept. A Workbench is a way of documenting how a specific activity has to be performed. A workbench is referred to as phases, steps, and tasks as shown in the following figure.
There are five tasks for every workbench:
Input: Every task needs some defined input and entrance,e criteria. So for every workbench we need defined inputs. Input forms the first steps of the workbench.
Execute: This is the main task of the workbench which will transform the input into the expected output.
Check: Check steps assure that the output after execution meets the desired result.
Production output: If the check is right the production output forms the exit criteria of the workbench.
Rework: During the check step if the output is not as desired then we need to again start from the execute step. ![enter image description here]
