Tech Breakfast #20 - Unit Testing and Dependency Injection Techniques

Unit Testing and Dependency Injection Techniques

We’ll use Asp.Net to make it more real Also:

• StructureMap for IoC/DI.
• NSubstitute for faking dependencies.
• NLog as a 3rd party dependency example.

Render a page / partial / widget:

• Downloads latest currency rate from web service.
• Serves a cached data before it expires.
• If a web service call fails, log an error (possibly by email)
• Should return null model if unable to get result. (view will render N/A state)

We will refactor our code to make it testable.
