Build Status
Built with Nuke
NuGet MyGet


This package aims to provide conversion of code coverage reports to the Cobertura format. Currently, it supports OpenCover and dotCover source formats. It can be either directly used via the CoberturaConverter NuGet package, as Dangl.Nuke.CoberturaConverter for the NUKE Build system or as command line tool via CoberturaConverter.CommandLine.

This project is based on Daniel Palmes OpenCoverToCobertura Converter, which is licensed under the Apache License.

dotCover Report Types

Because the filename attribute is mandatory in the Cobertura format, dotCover reports should always be generated with the DetailedXml setting instead of the regular Xml to output filenames. Otherwise, all classes in the dotCover report that do not have a source file specified are ignored.


If this is used in full .Net framework 4.6.1 and earlier, please add a reference to

<PackageReference Include="System.ValueTuple" Version="4.4.0" />
