System Testing: Why? What? & How?
Introduction:
‘Unit testing’ focuses on testing each unit of the code.
‘Integration testing’ focuses on testing the integration of “units of code” or components.
Each level of testing builds on the previous level.
‘System Testing’ is the next level of testing. It focuses on testing the system as a whole.
This article attempts to take a close look at the System Testing Process and analyze:
Why System Testing is done? What are the necessary steps to perform System Testing? How to make it successful?
How does System Testing fit into the Software Development Life Cycle?
In
a typical Enterprise, ‘unit testing’ is done by the programmers. This
ensures that the individual components are working OK. The ‘Integration
testing’ focuses on successful integration of all the individual pieces
of software (components or units of code).
Once the components
are integrated, the system as a whole needs to be rigorously tested to
ensure that it meets the Quality Standards.
Thus the System testing builds on the previous levels of testing namely unit testing and Integration Testing.
Usually a dedicated testing team is responsible for doing ‘System Testing’.
