Percentage Coverage on New Code

Quality Gate Quality Gates

New Code = methods added since the baseline. All non-UI new classes should be 100% covered.

The ~10% of a class that is hard to cover is not easily testable, hence badly designed and often error-prone: 100% coverage ensures this code gets tested.

CQLinq source

This quality gate is written in CQLinq, C# LINQ over the NDepend code model. It ships with every new NDepend project: you can read it, adapt it, or use it as a starting point for your own custom rules.
