Here is my UnitTest (the name of address at the start is test) :

using (MySqlConnection db = new MySqlConnection(connectionString))
{
MySqlTransaction transaction;

db.Open();
transaction = db.BeginTransaction();

new MySqlCommand("UPDATE t_adresse SET `nomAdresse`='forbl' WHERE idAdresse=8;",db, transaction).ExecuteNonQuery();

transaction.Rollback();

MySqlCommand cmdUpdateAdresse = new MySqlCommand("SELECT nomAdresse FROM t_adresse WHERE idAdresse=8", db);
MySqlDataReader data = cmdUpdateAdresse.ExecuteReader();
while (data.Read())
{
Assert.AreEqual("test", (string)data["nomAdresse"]);
}
db.Close();
}

And the test return that the value expected (test) doesn't match the actual value (forbl)
