Well, I thought I explained it well. Frankly, I'm shocked that folks don't know what test harnesses are. They are one of the oldest constructs in Software Engineering. In the days of old, we often called them "Unit Tests." If you want some concrete examples, here you go: Here's my "Spinner" widget: https://github.com/RiftValleySoftware/RVS_Spinner https://github.com/RiftValleySoftware/RVS_Spinner This is the four test harness apps: https://github.com/RiftValleySoftware/RVS_Spinner/tree/main/Tests/RVS_SpinnerTests https://github.com/RiftValleySoftware/RVS_Spinner/tree/main/... This is my checkbox widget: https://github.com/RiftValleySoftware/RVS_Checkbox https://github.com/RiftValleySoftware/RVS_Checkbox Here's the test harness app: https://github.com/RiftValleySoftware/RVS_Checkbox/tree/main/TestHarness/RVS_Checkbox_TestHarness https://github.com/RiftValleySoftware/RVS_Checkbox/tree/main... There's more, but these should be enough to illustrate the point.
