<p>The concept of domain testability of software is defined by applying the concepts of observability and controllability to software. It is shown that a domain-testable program does not exhibit any input-output inconsistencies and supports small test sets in which test outputs are easily understood. Metrics that can be used to assess the level of effort required in order to modify a program so that it is domain-testable are discussed. Assessing testability from program specifications and an experiment which shows that it takes less time to build and test a program developed from a domain-testable specification than a similar program developed from a nondomain-testable specification are also discussed.</p>
