测试函数的测试用例
2008-09-05 12:10:13
一天，主管要俺测试函数，倒是被吓了一跳。鄙人孤陋寡闻，没见过这方面的测试和用例。于是发明了一套，拿出来给各位长老点评。以下是设计的用例：
测试用例002 函数原型：static string InterceptString(string stringToSub, int length) 函数功能：截取字符串 输入数据 输出数据 American,length为3 Ame… 为空,length为3 空行 123456,length为3 123… 本人在北京一所民办高校,length为6 本人在… ccccccc,length为3 ccc ＜注释＞,length为3 ＜注... <注释>,length为3 <注... 测试表明，该函数实现了转换功能。可以正常使用。在特殊情况下会失效，如输入日文字符（函数使用的是匹配中文字符正则表达式) 由于测试的是网站(asp.net)，于是创建了一个网站工程。以下是驱动部分的代码（其实俺并不知驱动是啥）：
protected void Page_Load(object sender, EventArgs e)
{
string str1 = test.InterceptString("American",3);
Response.Write(str1);
Response.Write("<br/>");string str2 = test.InterceptString("", 3);
Response.Write(str2);
Response.Write("<br/>");string str3 = test.InterceptString("12345", 3);
Response.Write(str3);
Response.Write("<br/>");string str4 = test.InterceptString("本人在北京一所民办高校（哪个学校不说了）里面做程序开发，主要做的是招生系统。因为就我一个程序员，也算是技术总监了！", 6);
Response.Write(str4);
Response.Write("<br/>");string str5 = test.InterceptString("cccccc", 3);
Response.Write(str5);
Response.Write("<br/>");string str6 = test.InterceptString("＜注释＞", 3);
Response.Write(str6);
Response.Write("<br/>");string str7 = test.InterceptString("<注释>", 3);
Response.Write(str7);
Response.Write("<br/>");
}在App_code下兴建了一个类，是被调用的函数：
public static string InterceptString(string stringToSub, int length)
{
Regex regex = new Regex("[\u4e00-\u9fa5]+", RegexOptions.Compiled);
char[] stringChar = stringToSub.ToCharArray();
StringBuilder sb = new StringBuilder();
int nLength = 0;
for (int i = 0; i < stringChar.Length; i++)
{
if (regex.IsMatch((stringChar[i]).ToString()))
{
nLength += 2;
}
else
{
nLength = nLength + 1;
}if (nLength <= length)
{
sb.Append(stringChar[i]);
}
else
{
break;
}
}
if (sb.ToString() != stringToSub)
{
sb.Append("...");
}return sb.ToString();
}
