NDepend - Baseline Coverage by Assembly Query

Question

is it possible to have a comparison by assembly to the baseline build? At the moment I have a report that shows the coverage by assembly, but I would like to add the coverage compared to the baseline build for each assembly as well side by side. How would a query look like?

Thanks a lot.

This can be achieved with such CQLinq code query:

from a in Application.Assemblies

select new { a, a.PercentageCoverage,
olderCov = a.OlderVersion() == null ? -1 : 
           a.OlderVersion().PercentageCoverage,
diffCov = a.OlderVersion() == null ? -1 : 
          a.PercentageCoverage - a.OlderVersion().PercentageCoverage
}

Here is a screenshot of the result:

Several points:

• The query can be easily rewritten to show diff of other coverage metrics like a.NbLinesOfCodeCovered for example
• This query can be easily transformed into a rule for example if any coverage ratio is decreasing (related doc)
• Or if you prefer it not to be a rule but still gets this query result in the report, just use this feature (List code queries of this group in the report)
