ScAmPER: Generating Test Suites to Maximise Code Coverage in Interactive Fiction Games

摘要

We present ScAmPER, a tool that generates test suites that maximise coverage for a class of interactive fiction computer games from the early 1980s. These games customise a base game engine with scripts written in a simple language. The tool uses a heuristic-guided search to evaluate whether these lines of code can in fact be executed during gameplay and, if so, outputs a sequence of game inputs that achieves this. Equivalently, the tool can be seen as attempting to generate a set of test cases that maximises coverage of the scripted code. The tool also generates a visualisation of the search process.
