The Effort library provides multiple factory classes that developers can choose from as per their requirements, and all of them can serve well in different scenarios.
Factory Classes are capable of creating a different type of fake data endpoints, such as DbConnection, EntityConnection, and ObjectContext.
- Fake DbConnection objects are ideal for using them in the Code First programming approach.
- The purpose of fake EntityConnection objects is to utilize them in the Database First and Model First techniques.
- Instantiate ObjectContext objects by passing them as a constructor argument.
In Entity Framework, when you query data to retrieve all the products from the database. Behind the scenes, a connection is established with the appropriate database server, and an SQL command is executed.
The ObjectContextFactory class provides helper methods that can create ObjectContext instances that behave differently.
Effort makes it possible to eliminate this communication and run every required operation by the current process.
If you execute the above code, there will be no communication with your external database server. Instead, the data operations will be performed by an in-process lightweight database.
