Objectives testing
Alpha and Beta Testing
Before software is released, it is sometimes given to a small, selected group of potential users for trial use (alpha testing)
-
These users report problems with the product. Alpha and beta testing are often uncontrolled and are not always referred to in a test plan.
-
Regression Testing
Is the “selective retesting of a system or component to verify that modifications have not caused unintended effects and that the system or component still complies with its specified requirements.”
In practice, the approach is to show that software still passes previously passed tests in a test suite
The purpose of regression testing is to show that software behavior is unchanged by incremental changes to the software.
-
Installation Testing
Installation testing can be viewed as system testing conducted in the operational environment of hardware configurations and other operational constraints.
-
Performance Testing
Performance testing verifies that the software meets the specified performance requirements and assesses performance characteristics
The test objectives vary with the test
target; different purposes are addressed at different levels of testing.
