6.2 TESTING STRATEGIES:

Software Testing Strategies should follow generic characteristics:
1. Testing begins at the module level and works ‘out word’ towards the integration of the entire computer based system.
2. Different testing techniques are applied at each point.
3. Testing is conducted by developer of the software.

A strategy for software testing begins with Unit Testing; it concentrates on each unit of software as implemented in source code. Testing progresses by moving to Integration Testing, where the focus is on the design and the construction of software design.
Next Validation Testing is encountered, where requirements established as part of project requirement analysis are validated against the project that has been constructed. Finally we arrived at System Testing, where project and the other system elements are tested as a whole
