作为新的单元测试和测试驱动开发，我很难单元测试我刚刚为我正在编写的项目编写的新函数。我需要解析网页中的数据，并将关键数据存储在数据库中。我创建了一个结构来保存我将需要的单个记录，并且创建了一个结构列表来保存所有收集的数据，然后在解析数据时传回所述List。一切正常，但单元测试失败？我无法弄清楚为什么...请帮助！单元测试列表<struct>
这里的结构和功能：
//===================================================================================================================
/// lsBuildInstalData
/// <summary>
/// This function will parse out the required data from the input list and store it in a private struct.
/// Year (allowing up to 10) : Instalment Amount (pick up the first 4 and skip the rest) : Values (3 values; Year/InstalAmt/Due)
/// </summary>
///
/// Parameters
/// <param name="sTaxDataLine"> Data to parse the values out of.</param>
///
/// <returns> Struct List<> of the parsed values.</returns>
///
/// DataBase Use N/A
///
/// Change Log 04/23/14 MS Initial development.
///
//===================================================================================================================
public struct InstalData
{
// -- Set the properties...
private string sDueAmt, sInstalAmt, sYear;
public string DueAmt
{
get
{
return sDueAmt;
}
set
{
if (value.IsNotNullOrEmpty())
sDueAmt = value;
}
}
public string InstalAmt
{
get
{
return sInstalAmt;
}
set
{
if (value.IsNotNullOrEmpty())
sInstalAmt = value;
}
}
public string Year
{
get
{
return sYear;
}
set
{
if (value.IsNotNullOrEmpty())
sYear = value;
}
}
}
private List<InstalData> lsBuildInstalDataArray(List<string> lsTaxDataLine)
{
// -- Create the struct and list to pick up all the install data so we can store it correctly later...
InstalData sID = new InstalData();
List<InstalData> lsInstalData = new List<InstalData>();
// -- Loop through the data, pull what we need, and build the array...
foreach (string sLine in lsTaxDataLine)
{
sID.Year = sGetParsedValue("Year", sLine);
sID.InstalAmt = sGetParsedValue("Instal", sLine);
sID.DueAmt = sGetParsedValue("Due", sLine);
// -- ONLY pick up data when there is 'Prinicipal' or 'Surchareg'...
if ((FSH.Pos("Principal", sLine) > 0 || FSH.Pos("Surcharge", sLine) > 0) && sID.DueAmt != "0.00")
lsInstalData.Add(sID);
}
// -- Return the final array...
return lsInstalData;
}
这里是写列表中，为我自己调试目的的文件，以表明该数据是一样的注释掉的代码的单元测试。

感谢您的任何帮助，您可以提供！
附注 - 为什么你在函数之前有这个巨大的吓人评论？ –
你的'struct'不代表一个单一的值，并且几乎不符合什么使得一个合适的结构的任何指导。它应该是一个'类'。 – Servy
如果您使用的是NUnit，我会重构那个粗糙的设置来利用[TestCase]（http://nunit.org/?p=testCase&r=2.5）。作为一个经验法则，根据测试方法断言一件事。 – 48klocs
