by
David van Alphen

5. Dev/Test Theory
 OO Principles – SOLID
 Dependency Injection
 Enterprise Patterns
 Separation of Concerns
 Mocking / Stubbing
 Mockito, NSubstitute, etc

6. SOLID
 Wikipedia - SOLID
 SRP – Single Responsibility Principle
 A class should have one responsibility
 O – Open/Closed Principle
 Open for extension, closed for modification
 L – Liskov Substitution Principle
 Objects should be replaceable by subtypes without affecting correctness of
application
 I – Interface Separation Principle
 Many specific interfaces are better than one general interface
 D – Dependency Injection Principle
 Depend on abstract, not concrete classes

7. Dependency Injection
 Wikipedia - Dependency Injection
 No Static methods (workaround available)
 Constructors
 Setters

8. Salesforce & Testing
 Apex tests
 System or integration tests
 Unit tests
 Apexmocks framework
 Mix and Match

9. Mockito vs Apexmocks
 Apex vs Java
 No Generics, explicit typing
 Concrete classes
 Compile on platform

10. Apexmocks Generator
 interfacemocks.properties
 IMyClass=MyClass:MyParentClassOrInterface
 Mocks.cls
 .gitignore (or equivalent)

11. Code example 1

12. Code example 2

13. Test Structure
 Given
 Arrange things needed for the test
 When
 Trigger the behavior we want to test
 Then
 Confirm the results are what we expected

14. Code example 3

15. Things to Avoid
 Always focus on testing public / interface behaviour
 Use the framework wisely - don’t verify more behaviour
than you need to
 Don’t mock too deeply - if you find your unit test having
to set up a lot of mocking before you even trigger the
behaviour under test, that’s probably a hint that your
design could be better

16. Documentation and Help
