                .Returns(Task.FromResult(3));

            var valueGenMock = new Mock<IValueGeneratorSelector>();
            valueGenMock.Setup(m => m.Select(It.IsAny<IProperty>(), It.IsAny<IEntityType>())).Returns(Mock.Of<ValueGenerator>());

            var servicesMock = new Mock<IDatabaseProviderServices>();
            servicesMock.Setup(m => m.Database).Returns(database.Object);

            sourceMock.Setup(m => m.GetProviderServices(It.IsAny<IServiceProvider>())).Returns(servicesMock.Object);

            var services = new ServiceCollection();
            services.AddEntityFramework();
            services.AddInstance(sourceMock.Object);
            var serviceProvider = services.BuildServiceProvider();

            using (var context = new EarlyLearningCenter(serviceProvider, new DbContextOptionsBuilder().Options))
            {
                context.Entry(new Category { Id = 1 }).State = EntityState.Unchanged;
                context.Entry(new Category { Id = 2 }).State = EntityState.Modified;
                context.Entry(new Category { Id = 3 }).State = EntityState.Added;
                context.Entry(new Category { Id = 4 }).State = EntityState.Deleted;
                Assert.Equal(4, context.ChangeTracker.Entries().Count());

                await context.SaveChangesAsync();
            }

            Assert.Equal(3, passedEntries.Count);

            database.Verify(
