我正在尝试测试下面的方法但我在行using (var reader = command.ExecuteReader())
中得到错误,必须打开并且可用连接。我无法使用这种方法来恢复假读者。
测试方法
public EmailTemplateFilterModel[] GetEmailTemplateFilters()
{
var filterList = new List<EmailTemplateFilterModel>();
using (var connection = new SqlConnection(_clientConnString))
using (var command = connection.CreateCommand("cspGetInvoiceTemplateFilterCollections"))
{
if (connection.State != ConnectionState.Open)
connection.Open();
using (var reader = command.ExecuteReader())
{
while (reader.Read())
{
var filter = new EmailTemplateFilterModel
{
ParmId = (int)reader["InvoiceEmailMapParmId"],
ParmName = (string)reader["ParmName"],
DatabaseDataType = (string)reader["DbDataType"],
ControlType = (string)reader["ControlType"],
StoredValue = (string)reader["StoredValue"],
DisplayedValue = (string)reader["DisplayedValue"]
};
filterList.Add(filter);
}
}
}
return filterList.ToArray();
}
单元测试

//ARRANGE
ShimSqlConnection.AllInstances.Open = (sender) => { };

};
};
ShimSqlDataReader.AllInstances.Read = (sender) =>
{
rowCounter++;
return rowCounter <= 2;
};
ShimSqlDataReader.AllInstances.ItemGetString = (sender, coloumnName) =>
{
if (rowCounter == 1)
{
switch (coloumnName)
{
case "InvoiceEmailMapParmId":
return 1;
