Decorated method with test-attribute

- Test passes
- some formatting
Split RunTime Tests into three TestFixtures

- Each fixture tests a specific class
- This provides better guidance where to add tests
Removed unused parameter

- some methods made static
- constants naming made congruent
Added UTF and ANSI to the known abbreviations of ReSharper

- also some migration seems to be run, hope does not hurt
