I have a completely different view on that. Maybe because I work with harnesses for decades already. The perl test suite is called harness. It's a build and test system, which makes it easy to test and run all supported platform and config options, and app/lib features and regressions. Like a CI. Basically a CI is the best harness. The agent is just a feedback loop between the model and the harness. Since the feedback loop must be fast, a real CI is too costly, and only serves as end verification. So a good harness enables fast tests for features per arch. With proper cleanup and parallelization.
