Test design concerns making the decisions on (1) what to and what not to test, (2) how to stimulate the system and with what data values, and (3) how the system should react and respond to the stimuli. It is a separate task from test execution and is done before executing the tests against the system. Test design techniques, on the other hand, are ...
Boundary Value Analysis
Boundary value analysis is a refinement of the equivalence class partitioning method which again is one of the most generally applicable methods for black-box test design. The idea of equivalence class partitioning is to divide the all possible inputs to the system into “equivalence classes”, i.e. sets of inputs that should produce “analogous” ...
