This would allow to reuse the same test code for different permutations of

  • Virtual/non-virtual/Lazy loading/Proxies
  • Auto/backing fields/indexer/no property
  • public/private field/property
  • public setter/private setter/readonly/constructor only
  • Snapshot/Changed/Full notifications
  • new/override/explicit implementation properties
  • nullable/non-nullable properties and navigations
  • CLR default/custom default/calculated property
  • Reference and collection navigations non-initialized/initialized in constructor
  • Navigations to exact type/base/interface
  • Custom Equals/GetHashCode
  • Collection types (IEnumerable/read-only/immutable/etc.)

    Design proposal:

    • Tests are written against interfaces that are implemented implicitly or explicitly by DbContext and model classes
    • The entity class generator takes an IModel created with a sample implementation as an input and outputs the requested DbContext and model classes implementations in .cs files
