I'm using Sonar 3.0.1 with the C-Sharp Plugins Ecosystem plug-in.
When running an analysis with the Simple Java Runner I don't receive any test coverage reports, instead Gallio prints the following error.
ERROR c.g.TestReportSensor - Source file not found for test report
This file means that if I have file Calc.cs and TestCalc.cs, Gallio cannot find the former and as a result cannot produce any coverage report.
I follow the default test project naming convention and Sonar easily qualify my test project as one.
Generally, such error means that the assemblies used by Gallio when executing the unit tests were not "freshly" compiled or moved out of the standard "bin/debug" folder before running Sonar.
