Testing Internal Methods in C#
October 16, 2018
When you have a C# project that contains methods marked internal, they can be tested from a separate Tests project.
In the project to be tested, open up Properties/AssemblyInfo.cs and add
[assembly: InternalsVisibleTo("ViewerTests")]
where ViewerTests is the name of the project that contains the tests.
This ViewerTests project will now be able to refer to internal methods.
