c# - Assert.AreEqual 失败错误 C#

Question

我对这一切都很陌生，所以任何帮助都将不胜感激。

我已经从 url 方法创建了一个下载图像，我需要对其进行测试。 我已尝试填写测试参数，但我不确定要输入什么。

你能告诉我要去哪里吗，

谢谢。亚伦

[TestMethod()]
public void DownloadImageFromURLTest()
{
    string url = "http://www.omnimedicalsearch.com/conditions-diseases/images/skin-mole.jpg";
    Image expected = Image.FromFile(@"C:\Users\Public\Pictures\Sample Pictures\skin-mole.jpg");
    Image actual = Image.FromFile(@"C:\Users\Public\Pictures\Sample Pictures\skin-mole.jpg"); ;
    actual = CloudConnection.DownloadImageFromURL(url);
    Assert.AreEqual(expected, actual);
    Assert.Inconclusive("Verify the correctness of this test method.");
}

Answer 1

试试这个:

  string url = "http://www.omnimedicalsearch.com/conditions-diseases/images/skin-mole.jpg";
  Image expected = Image.FromFile(@"C:\Users\Public\Pictures\Sample Pictures\skin-mole.jpg");
  Image actual = Image.FromFile(@"C:\Users\Public\Pictures\Sample Pictures\skin-mole.jpg"); ;
  actual = CloudConnection.DownloadImageFromURL(url);

  MemoryStream ms = new MemoryStream();
  expected.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
  String expectedBitmap = Convert.ToBase64String(ms.ToArray());
  ms.Position = 0;
  actual.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
  String actualBitmap = Convert.ToBase64String(ms.ToArray());

  Assert.AreEqual(expectedBitmap, actualBitmap);
