5. Worse than you think
In 1976, G.J. Meyers described a 100-line program that had unique paths.

6. How do you test this?

7. Agenda What we won’t talk about What we’ll talk about TDD
Javascript testing
Production ready code
What we’ll talk about
Setup tests
Remove database
Keep it simple

8. Demo: Sample Application

9. Unit test framework
MSTest
NUnit
xUnit
Others

10. Unit test runner
MSTest
NUnit
Resharper
NCrunch
Others

11. Demo: Our first test

12. Default Data access Difficult to test There is no IDbContext
Controller
Context
Entity Framework
Difficult to test
There is no IDbContext
DbContext tightly bound to EF (EntityFramework.dll)

13. Removing database access
Repositories
Mocks
Dependency Injection

14. Repositories Easy to test IRepository Extrapolate away from Context
Controller
Repository
Context
Entity Framework
Easy to test
IRepository
Extrapolate away from Context

15. Mocks
Controller
Repository
Mock
Allows us to fake the database

16. Testing vs. runtime Controller Repository Mock Context
Entity Framework

17. How we normally instantiate
Class1
Class2
new Class2()

18. Dependency injection
Class1
ClassA
IClass2()
ClassA : IClass2

19. Dependency injection Allows for loose coupling
Inversion of control (IOC)
IOC Container

20. Demo: Removing Database access

21. Selectlist
ViewBag
ViewModel
Automapper

22. Demo: SELECTLIST
