Geometric Theory for Program Testing (2206.02083v1)

Published 5 Jun 2022 in cs.SE and cs.PL

Abstract: Formal methods for verification of programs are extended to testing of programs. Their combination is intended to lead to benefits in reliable program development, testing, and evolution. Our geometric theory of testing is intended to serve as the specification of a testing environment, included as the last stage of a toolchain that assists professional programmers, amateurs, and students of Computer Science. The testing environment includes an automated algorithm which locates errors in a test that has been run, and assists in correcting them. It does this by displaying, on a monitor screen, a stick diagram of causal chains in the execution of the program under test. The diagram can then be navigated backwards in the familiar style of a satnav following roads on a map. This will reveal selections of places at which the program should be modified to remove the error.
