Test_Training

Restrict: this is simulate production code, so

1. CAN'T change signature.
2. CAN'T make accessibility level from non-public to public

Project sequence

• 1.XmasChecker
  • for dependency can't control
  • to learn how to deal with DateTime type
• 2.RsaSecureToken    - learn loose dependency by Interface
  • introduce stub/mock framework (NSubstitute)
  • DI / IoC
• 3.IsolatedByInheritanceAndOverride
  • isolated by inheritance and virtual keyword
  • mock object to verify
• 4.BaseClassCoupling
  • isolated static dependency
  • inheritance override
  • property injection
• 5.AssertionSamples
  • compare object by properties
  • partial compare
  • verify Exceptions
• 6.ServerApiDependency (sum up challenge)
  • remove static dependency
  • knowing inheritance and override to loose coupling
  • mock object for Assersion
  • verify Exceptions by FluentAssertion

tips: 傳入 stub 物件的多種方式，可參考：

• 1. 透過 target 的 constructor 傳入 interface/abstract 的 instance (DI auto-wiring)
• 2. 透過 target 的 public property 傳入 (DI auto-wiring)
• 3. target 方法的參數 (常看到傳入的參數型別為 interface的那種情況)
• 4. target 將欲 stub 的方法擷取成 protected virtual 方法，使用 繼承 + override 的方式來測試原始target class
