	/// <summary>
	/// This test verifies that UoW commits changes in a transaction.
	/// Test is carried on by:
	/// - running a transaction with exclusive lock on table LastUpdatingLog with the base.SqlConnection
	/// - running the sut.Update (which opens another write transaction)
	/// - execute SELECTs using another connection (with NoLock for checking uncommitted values)
	/// The sut can commit its transaction only after first transaction is committed
	/// </summary>

	namespace JsonSerialization
	{
	public class UnitTest1
	{
	private const string json = @"{""panes"":{""filter"":{""records"":[{""data"":{""customernumber"":""10002""}}]}}}";
