EfCore.InMemoryHelpers

Actively Maintained
Build status
NuGet Status

Provides a wrapper around the EF Core In-Memory Database Provider. Specifically works around the following EF bugs.

  • InMemory: Improve in-memory key generation <br>
    Reasoning: For many bootstrapping and integration tests, the id generation should be predictable, i.e. an in-memory persistence should not share static mutable state. This is especially important when using unit tests as a bootstrap to generate ad-hoc data.
  • Add index validation<br>
    Reasoning: It is desirable for indexes to be validated when running unit tests. This allows bugs to be caught earlier without the need for integration testing against a real database.
  • Add support for Timestamp/row version ([Timestamp], and .Property(p =&gt; p.X).IsRowVersion())<br>
    Reasoning: It is desirable for exceptions to be thrown when a update violates a RowVersion. This allows bugs to be caught earlier without the need for integration testing against a real database.

NuGet

PM> Install-Package EfCore.InMemoryHelpers

Usage

The main entry point is InMemoryContextBuilder which can be used to build an in-memory context.

using (var context = InMemoryContextBuilder.Build<MyDataContext>())
{
    var entity = new MyEntity
    {
        Property = "prop"
    };
    context.Add(entity);
    context.SaveChanges();
}

A custom DbContextOptionsBuilder can be passed in:

var builder = new DbContextOptionsBuilder<MyDataContext>();
using (var context = InMemoryContextBuilder.Build<MyDataContext>(builder))
{
    var entity = new MyEntity
    {
        Property = "prop"
    };
    context.Add(entity);
    context.SaveChanges();
}

Both the above usages assume that the target context has a public constructor that accepts a DbContextOptions.

public MyDataContext(DbContextOptions options)
    :
    base(options)
{ }

If this is not the case a custom context constructor can be passed in:

var builder = new DbContextOptionsBuilder<MyDataContext>();
using (var context = InMemoryContextBuilder.Build(builder, options => new MyDataContext(options)))
{
    var entity = new MyEntity
    {
        Property = "prop"
    };
    context.Add(entity);
    context.SaveChanges();
}
