Jamie, the easiest (and most straightforward) way in which this could be implemented is automatically excluding stuff with a complexy of 0 (simple setter, getter, empty custructor) or another configurable complexity level. Taking it further, could mean defining a success ratio, which could be expressed as: my code coverage is acceptable if 95% of my branches are covered. This again shows success when not covering a method without branches (or complexity). This could be visualized the same way unittest success is (red=bad/green=good). Eventually you might be able te not show percentages over LOCs/ covered LOCs, but Branches/ covered branches.

Ian, at the moment there is nothing like this. Can you suggest it on the NCover forums?

Olaf, what you say makes sense. I don't know about any innitiatives to do this. The trick would be making it easy to visualize.

sounds like a neat trick, though I have been giving CodeCoverage some though within the context of the team I work... conclusion was that it might be desirable not to measure test coverage agains code-statements, but to measure test coverage agains complexity. Since there are ways to determine the complexity of code (such as "Cyclomatic Code Complexity") it might be well possible to measure test-coverage in a way that makes more sense... Do you know about innitiatives in this direction? Does my conclusion hold?

I wish to be able to exclude some error checking code from coverage, e.g. if (arg == null) { Throw new … } Would it be possible to write something like? if (arg == null) { CoverageExcludeBasicBlock(); Throw new … } Ian Ringrose www.ringrose.name email address on website
