Software Testing Methodologies Dichotomies

The best approach to do domain is testing is to stay away from it by making things simple such that the testing is not required
Orthogonal domain boundaries, consistent closure, independent boundaries, linear boundaries, etc.., make the domain testing easier
Non-linear boundaries can be converted into equivalent linear boundaries. This can be done by applying linearizing transformation
Nice boundaries come in parallel sets. Non- parallel inequalities can be converted into a set of orthogonal boundaries inequalities by suitable co-ordinate transformations
Testing can be divided into several steps that can be merged and made small that can be converted into a canonical program form
