Figure 4: Unit test project templates
Xamarin Studio and Visual Studio both provide a number of test project templates targeting different areas of a cross-platform project. In Xamarin cross-platform projects, unit tests can be categorized into two groups: platform-agnostic and platform-specific testing.
Platform-agnostic unit tests
Platform-agnostic components, such as portable class libraries containing shared logic for Xamarin applications, can be tested using the common unit test projects targeting the .NET...
