Case Study: Complex UI Testing

DZone

Large and Complex UI 90%+ Covered by Tests. In this previous post, I used the example of the new NDepend v2020.1 graph. This new tool is a large and complex UI with dozens of actions proposed to the user and a drastic performance requirement (it scales live on 100.000+ elements). This graph implementation is 90% covered by tests. It is not because there is a lot of UI code that it should not be well tested. We didn't spend a good part of our resources in writing tests just for the sake of it.

The tipping point is the threshold at which a query plan will "tip" from seeking a non-covering nonclustered index to scanning the clustered index or heap. The basic formula is: A clustered index (or table) scan will occur when estimated rows exceeds 33% of the number of pages in the table.
