💡 Why Use MockQueryable?

Avoid hitting the real database in unit tests when querying via IQueryable:

var query = _userRepository.GetQueryable();

await query.AnyAsync(x => ...);
await query.FirstOrDefaultAsync(x => ...);
await query.ToListAsync();
// etc.

🚀 Getting Started

1. Create Test Data

var users = new List<UserEntity>
{
    new UserEntity { LastName = "Smith", DateOfBirth = new DateTime(2012, 1, 20) },
    // More test data...
};

2. Build the Mock

var mock = users.BuildMock(); // for IQueryable

3. Set Up in Your favorite Mocking Framework

Moq

_userRepository.Setup(x => x.GetQueryable()).Returns(mock);

NSubstitute

_userRepository.GetQueryable().Returns(mock);

FakeItEasy

A.CallTo(() => userRepository.GetQueryable()).Returns(mock);

🗃️ Mocking `DbSet<T>`

var mockDbSet = users.BuildMockDbSet();

// Moq
var repo = new TestDbSetRepository(mockDbSet.Object);

// NSubstitute / FakeItEasy
var repo = new TestDbSetRepository(mockDbSet);

🔧 Adding Custom Logic

Example: Custom `FindAsync`

mock.Setup(x => x.FindAsync(userId)).ReturnsAsync((object[] ids) =>
{
    var id = (Guid)ids[0];
    return users.FirstOrDefault(x => x.Id == id);
});

Example: Custom Expression Visitor

Build a mock with the custom SampleLikeExpressionVisitor for testing EF.Functions.Like

var mockDbSet = users.BuildMockDbSet<UserEntity, SampleLikeExpressionVisitor>();

🧩 Extend for Other Frameworks

You can even create your own extensions. Check the example here.

NuGet packages (3)

Showing the top 3 NuGet packages that depend on MockQueryable.Core:

Package	Downloads
MockQueryable.EntityFrameworkCore Core package for MockQueryable extensions for mocking operations such ToListAsync, FirstOrDefaultAsync etc. When writing tests for your application it is often desirable to avoid hitting the database. The extension allows you to achieve this by creating a context – with behavior defined by your tests – that makes use of in-memory data.	28.0M
