Functional testing techniques

Functional testing techniques:

• Functional analysis
• Equivalence partitioning
• Boundary value analysis

Specification Vs. Implementation

The basic approaches to testing software are based on its specification and implementation

• White box testing – test cases and data are constructed based on the code that implements the software
• Quality and correctness of computations is validated
• Will not be further discussed in this tutorial
• Black box testing – test cases and data are constructed based solely on the software’s specification

Functional System Testing:

• Testing of a completed application to determine that it provides all of the behaviors required of it.
• Testing of completed increments that provide some degree of end-user functionality.
• Search for defects that are variances between the actual operation of the system and the requirements for the system.
• System is treated as a black box.
