使用 Microsoft Fakes 将 VS 2010 的 Pex TestMethods 转换为 VS2013

Question

我正在尝试将下面的 pex 测试方法转换为正常的单元测试。虽然我打算在需要的地方使用 Microsoft Fakes，但我想先了解一些事情。

[TestMethod]
[PexGeneratedBy(typeof(ErrorLogTest))]
public void Initialize139()
{
    ErrorLog errorLog;
    NameValueCollection nameValueCollection;
    errorLog = new ErrorLog();
    errorLog.MyProperty = false;
    KeyValuePair<string, string>[] keyValuePairs = new KeyValuePair<string, string>[5];
    KeyValuePair<string, string> s0 = new KeyValuePair<string, string>("", "");
    keyValuePairs[0] = s0;
    KeyValuePair<string, string> s1 = new KeyValuePair<string, string>("", "");
    keyValuePairs[1] = s1;
    KeyValuePair<string, string> s2 = new KeyValuePair<string, string>("", "");
    keyValuePairs[2] = s2;
    KeyValuePair<string, string> s3 = new KeyValuePair<string, string>("", "");
    keyValuePairs[3] = s3;
    KeyValuePair<string, string> s4 = new KeyValuePair<string, string>("", "");
    keyValuePairs[4] = s4;
    nameValueCollection = PexFactories.CreateNameValueCollection(keyValuePairs);
    this.Initialize(errorLog, "", nameValueCollection);
    Assert.IsNotNull((object)errorLog);
    Assert.AreEqual<bool>(false, errorLog.MyProperty);
}

我已将其转换为如下所示的简单单元测试：

[TestMethod]
public void Initialize1390()
{
    ErrorLog errorLog;
    NameValueCollection nameValueCollection = new NameValueCollection();
    errorLog = new ErrorLog();
    errorLog.MyProperty = false;
    KeyValuePair<string, string>[] keyValuePairs = new KeyValuePair<string, string>[5];
    KeyValuePair<string, string> s0 = new KeyValuePair<string, string>("", "");
    keyValuePairs[0] = s0;
    KeyValuePair<string, string> s1 = new KeyValuePair<string, string>("", "");
    keyValuePairs[1] = s1;
    KeyValuePair<string, string> s2 = new KeyValuePair<string, string>("", "");
    keyValuePairs[2] = s2;
    KeyValuePair<string, string> s3 = new KeyValuePair<string, string>("", "");
    keyValuePairs[3] = s3;
    KeyValuePair<string, string> s4 = new KeyValuePair<string, string>("", "");
    keyValuePairs[4] = s4;                
    errorLog.Initialize("", nameValueCollection);
    Assert.IsNotNull((object)errorLog);
    Assert.AreEqual<bool>(false, errorLog.MyProperty);
}

我这里有两个问题：

在从 pexmethod 到 testmethod 的转换中，我是否丢失了任何场景？
我在 nameValueCollection 中看到计数。返回的计数值为1，是因为我插入的所有KeyValuePair都一样吗？

Answer 1

您的新测试似乎缺少将 keyValuePairs 数组的内容复制到 nameValueCollection 集合中的步骤。我相信这是在原始测试中通过以下行完成的：

nameValueCollection = PexFactories.CreateNameValueCollection(keyValuePairs);
