dotCover is not showing Code Coverage

Symptoms

The assemblies you are trying to cover are not present in the coverage report or have 0% coverage.

Possible cause

• dotCover is unable to find assemblies’ PDB files.
• Assemblies’ PDB files do not match corresponding DLL files. For example:
• the files were created by different builds;
• DLL files were obfuscated.

Solution

dotCover integrated in Visual Studio

• Disable solution structure matching in the coverage results toolbar:
  
  
• Check that your target assemblies are built with PDBs.
• Check that the results are not filtered out with coverage filters (see dotCover | Edit Coverage Filters in the main menu).
• In ReSharper | Options… | Tools | Unit Testing, disable Shadow-copy assemblies being tested.
• Try to Drop coverage data with a trash bin icon

dotCover console runner

• Check that your target assemblies are built with PDBs.
• Check that the results are not filtered out with coverage filters.

(NUnit) Disable shadow-copying by running coverage with an additional /noshadow argument.
