Here’s what people at my course in Norway had to say at the end of the day to the question “Tell me one thing you “got” today “:

• Lambda expressions (many of the isolation frameworks require heavy use of Lambda Expressions)
• Stub vs. Mock – the differences
• The different isolation frameworks (Isolator, Rhino Mock, Moq)
• How to Fake methods on classes
• Faking static methods (using Isolator, and refactoring)
• How to fake stuff in general
• Learned i have a lot to learn
• How to use moq
• How to test classes with many dependencies
• Test first actually works! (many felt today that writing the test first was just “automatic” without any thought – and really helped)
• Why good test naming is important (also helps direct you when you are “lost” in the test
• Design by contract removes waiting for other teams in the company
