比基本测试多个循环。。。

package mainimport (	"testing"	"net/http")const checkMark = " OK! "const ballotX = " ERROR! "	func TestDownload(t *testing.T) {	var urls = []struct {		url 	string		statusCode int	}{		{			"http://localhost:8000/test.html", http.StatusOK,		},		{			"http://localhost:8000/test.html2", http.StatusNotFound,		},	}			t.Log("Given the need to test downloading content.")	{		for _, u := range urls {			t.Logf("\tWhen checking \"%s\" for status code \"%d\"", u.url, u.statusCode)			{				resp, err := http.Get(u.url)				if err != nil {					t.Fatal("\tShould be able to make the Get call.", ballotX, err)				}				t.Log("\t\tShould be able to make the Get call.", checkMark)				defer resp.Body.Close()								if resp.StatusCode == u.statusCode {					t.Logf("\t\tShould receive a \"%d\" status, %v", u.statusCode, checkMark)				} else {					t.Errorf("\t\tShould receive a \"%d\" status. %v %v", u.statusCode, ballotX, resp.StatusCode)				}			}		}	}}
