Not suported with EF6: BulkUpdateAsync, BulkDeleteAsync, SingleUpdateAsync.

Hi Guys. I use MockQueryable approach for EF async methods testing. But I've noticed that it doesn't work for async methods for collections, exactly 'bulk extensions': https://entityframework-extensions.net/bulk-update

Message: System.AggregateException : One or more errors occurred. (Field '_queryCompiler' defined on type 'Microsoft.EntityFrameworkCore.Query.Internal.EntityQueryProvider' is not a field on the target object which is of type 'TestAsyncEnumerableEfCore[TEntity]'.) ---- System.ArgumentException : Field '_queryCompiler' defined on type 'Microsoft.EntityFrameworkCore.Query.Internal.EntityQueryProvider' is not a field on the target object which is of type 'TestAsyncEnumerableEfCore[TEntity]'.

After some investigation, I found out that Bulk extensions methods require using EntityQueryProvider as provider and IQueryCompiler as _queryCompiler field.

I use the next code to set up async EF methods for testing:

private Mock<DbSet<TEntity>> DbSetConfigureForAsync<TEntity>(Mock<DbSet<TEntity>> dbSet, IQueryable<TEntity> data)
    where TEntity : class
{
    var enumerable = new TestAsyncEnumerable<TEntity>(data);

    // Configure queryable calls
    dbSet.As<IQueryable<TEntity>>().Setup(m => m.Provider).Returns(enumerable);
    dbSet.As<IQueryable<TEntity>>().Setup(m => m.Expression).Returns(data.Expression);
    dbSet.As<IQueryable<TEntity>>().Setup(m => m.ElementType).Returns(data.ElementType);
    dbSet.As<IQueryable<TEntity>>().Setup(m => m.GetEnumerator()).Returns(data.GetEnumerator());

    // Configure async enumerable calls
    dbSet.As<IAsyncEnumerable<TEntity>>()
        .Setup(m => m.GetAsyncEnumerator(It.IsAny<CancellationToken>()))
        .Returns(enumerable?.GetAsyncEnumerator());

    // Configure DbSet calls
    dbSet.Setup(m => m.AsQueryable()).Returns(enumerable); // alternative: _mockSet.Object
    dbSet.Setup(m => m.AsAsyncEnumerable()).Returns(CreateAsyncMock(data));

    return dbSet;
}

Thanks.
