  • EF Core In-Memory Database Provider

    原文链接

    This can be useful for testing, although the SQLite provider in in-memory mode may be a more appropriate test replacement for relational databases.

    Supported Database Engines

    • Built-in in-memory database (designed for testing purposes only)

    Supported Platforms

    • .NET Framework (4.5.1 onwards)

    • .NET Core

    • Mono (4.2.0 onwards)

    • Universal Windows Platform

    Testing with InMemory

    The InMemory provider is useful when you want to test components using something that approximates connecting to the real database, without the overhead of actual database operations.

    InMemory is not a relational database

    EF Core database providers do not have to be relational databases. InMemory is designed to be a general purpose database for testing, and is not designed to mimic a relational database.

    Some examples of this include:

    • InMemory will allow you to save data that would violate referential integrity constraints in a relational database.

    • If you use DefaultValueSql(string) for a property in your model, this is a relational database API and will have no effect when running against InMemory.

    For many test purposes these differences will not matter. However, if you want to test against something that behaves more like a true relational database, then consider using SQLite in-memory mode.
