?????? 有時程序使用HttpWebRequest與HttpWebResponse實現HTTP的訪問，但我們想測試它們不太容易實現。現在我們可以使用Moles框架來實現對它的單元測試。如果您還不了解Moles，可以先到官方網站看這個文檔。下面我們來看片段代碼:
[
TestMethod ]
[
HostType (
"Moles" )]
[
Description (
"Testing with moles assemblies" )]
public void Get_KnownUrl_ReturnsExpectedValue()
{
var mockedWebResponse =
new MHttpWebResponse ();
MHttpWebRequest .
AllInstances .GetResponse = (x) =>{
return mockedWebResponse;};
var googleUri =
new Uri (
"http://www.google.com" );mockedWebResponse.StatusCodeGet = () => {
return HttpStatusCode .OK; };mockedWebResponse.ResponseUriGet = () => {
return googleUri; };mockedWebResponse.ContentTypeGet = () => {
return "testHttpResponse" ; };
string mockedResponseStr =
@"<html> \r\n" +
" <head></head> \r\n" +
" <body> \r\n" +
" <h1>Hello World</h1> \r\n" +
" </body> \r\n" +
"</html>" ;mockedWebResponse.ContentLengthGet = () => {
return mockedResponseStr.Length; };
using (
var memoryStream =
new MemoryStream ()){
using (
var sw =
new StreamWriter (memoryStream)){sw.Write(mockedResponseStr);sw.Flush();memoryStream.Seek(0,
SeekOrigin .Begin);mockedWebResponse.GetResponseStream = () => memoryStream;
//act var request =
WebRequest .Create(
"http://www.google.com" );
var response = (
HttpWebResponse )request.GetResponse();
// Assert string htmlContent =
null ;
using (
var streamReader =
new StreamReader (response.GetResponseStream())){htmlContent = streamReader.ReadToEnd();}
Assert .AreEqual(
HttpStatusCode .OK, response.StatusCode);
Assert .AreEqual(mockedResponseStr.Length, response.ContentLength);
Assert .AreEqual(mockedResponseStr, htmlContent);
Assert .AreEqual(googleUri, response.ResponseUri);}}
}
