大家好我搜索IEnumerator但无法理解它.如果有人帮助我,这将是很大的帮助.
基本上试图了解它在这段代码中的作用
string requestUriString = URL;
if (requestUriString.IndexOf("http://", StringComparison.InvariantCultureIgnoreCase) < 0)
{
requestUriString = "http://" + requestUriString;
}
WebRequest request = WebRequest.Create(requestUriString);
try
{
IEnumerator enumerator;
StreamReader reader = new StreamReader(request.GetResponse().GetResponseStream(), Encoding.UTF8);
string sSourceString = reader.ReadToEnd();
reader.Close();
string str6 = this.funcParseStringFromString2String(sSourceString, "<div class=\"title\">", "<div class=\"searches_related\">", false);
ArrayList list = new ArrayList();
list = this.funcParseStringFromString2Stringx(str6, "<h3><a ", "</h3>", false);
int num = this.DataGridView2.RowCount + 1;
try
{
enumerator = list.GetEnumerator();
while (enumerator.MoveNext())
{
string str8 = Conversions.ToString(enumerator.Current);
string str7 = this.funcParseStringFromString2String(str8, …我有代码:
try:
print test.qwerq]
try:
print test.sdqwe]
except:
pass
except:
pass
如何在嵌套try中打印所有错误的调试信息？
对于在jUnit测试中抛出异常的方法,您如何处理？如您所见,该类中的addAnswer方法Question可能会抛出异常.在shouldFailifTwoAnswerAreCorrect方法中,我想检查是否抛出了异常,但是在shouldAddAnswersToQuestion
我应该MultipleAnswersAreCorrectException从私有addAnswerToQuestion方法中添加throws 并尝试/ catch shouldAddAnswersToQuestion或者在该方法中抛出它吗？
当方法在测试中抛出异常时,你会怎么做？
public class QuestionTest {
private Question question;
@Before
public void setUp() throws Exception {
question = new Question("How many wheels are there on a car?", "car.png");
}
@Test
public void shouldAddAnswersToQuestion() {
addAnswerToQuestion(new Answer("It is 3", false));
addAnswerToQuestion(new Answer("It is 4", true));
addAnswerToQuestion(new Answer("It is 5", false));
addAnswerToQuestion(new Answer("It is 6", false));
assertEquals(4, question.getAnswers().size());
}
@Test(expected = MultipleAnswersAreCorrectException.class)
public void shouldFailIfTwoAnswersAreCorrect() { …我有以下Python(3.2)代码:

private Item populateData(Item i) {
List<Person> groupIdList = xyzDao.getData(id);
for (Person p: groupIdList) {

}
我想通过模拟groupIdList来测试函数如何执行此操作？
我有一个我之前写过的脚本,现在正在尝试创建一个主页来运行这个脚本和其他脚本.我知道我必须把它变成一个函数然后在nesicary时调用它但我在函数部分遇到了一些麻烦.非常感谢任何帮助和建议.下面是我引用的脚本.
#A Python math script
a = float(raw_input("Enter the first number: "))
b = float(raw_input("Enter the second number: "))
print "Your answer is: ",(a*b)
