用于单元测试的XML数据

我们希望通过一些单元测试来运行大量数据。我们希望在某种excel电子表格或XML文档中定义这一点

单元测试框架可以加载这些数据作为输入和期望

我可以预见这会有异常捕获的问题。欢迎对此发表任何意见。

可以驱动来自XML文档或数据库等数据源的测试。

对于MSTest，请查看属性。

nUnit fixture只是POCO，因此您可以使用.NET类以任何方式设置它。因为它可能包含大量数据，我可能会在TestFixtureSetUp中进行设置，该设置在整个套件中运行一次：

[TestFixture]
public class Foo{

  private XmlDocument doc;
  private BarClass bar;

 [TestFixtureSetUp]
  public void FixtureSetUp(){
     doc = new XmlDocument();
     doc.Load("c:\file.xml");
  }

  [SetUp]
  public void SetUp(){
      BarClass = new BarClass();
  }

  [Test]
  public void TestX(){
     Assert.That(BarClass.DoSOmething(doc), Is.Baz);
  }

}

在花了几个小时寻找如何做到这一点（因为数据中嵌入了一些格式，所以我无法使用CSV文件）之后，我设法找到了如何在MSTest中使用XML的方法

这是一个小样本。希望能有帮助

假设您有一个简单的类库：

public class GetStrings
{
    public string RichardIII(string lookup)
    {
        string results;
        switch(lookup)
        {
            case "winter":
                {
                    results =
                        "Now is the winter of our discontent\nMade glorious summer by this sun of York;\nAnd all the clouds that lour'd upon our house\nIn the deep bosom of the ocean buried. ";
                    break;
                }
            case "horse":
                {
                    results =
                        "KING RICHARD III \nA horse! a horse! my kingdom for a horse!\n\nCATESBY \n\"Withdraw, my lord; I'll help you to a horse.\"";
                    break;
                }
                default:
                results = null;
                break;
        }
        return results;
    }
}

因此，将检查此方法一部分的单元测试如下所示：

[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|\\TestStrings.xml", "Test", DataAccessMethod.Sequential), DeploymentItem("GetStringsTest\\TestStrings.xml"), TestMethod]
public void RichardIIITest()
{
    GetStrings target = new GetStrings(); 

    string lookup = TestContext.DataRow["find"].ToString();
    string expected = TestContext.DataRow["expect"].ToString();
    if (expected == "(null)")
        expected = null; 

    string actual = target.RichardIII(lookup);
    Assert.AreEqual(expected, actual);
}

<TestStrings>
    <Test find="winter" expect="Now is the winter of our discontent&#10;Made glorious summer by this sun of York;&#10;And all the clouds that lour'd upon our house&#10;In the deep bosom of the ocean buried. "/>
    <Test find="horse" expect="KING RICHARD III &#10;A horse! a horse! my kingdom for a horse!&#10;&#10;CATESBY &#10;&#34;Withdraw, my lord; I'll help you to a horse.&#34;"/>
    <Test find="blah blah" expect="(null)"/>
</TestStrings>

xml文件TestStrings.xml如下所示：

[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|\\TestStrings.xml", "Test", DataAccessMethod.Sequential), DeploymentItem("GetStringsTest\\TestStrings.xml"), TestMethod]
public void RichardIIITest()
{
    GetStrings target = new GetStrings(); 

    string lookup = TestContext.DataRow["find"].ToString();
    string expected = TestContext.DataRow["expect"].ToString();
    if (expected == "(null)")
        expected = null; 

    string actual = target.RichardIII(lookup);
    Assert.AreEqual(expected, actual);
}

<TestStrings>
    <Test find="winter" expect="Now is the winter of our discontent&#10;Made glorious summer by this sun of York;&#10;And all the clouds that lour'd upon our house&#10;In the deep bosom of the ocean buried. "/>
    <Test find="horse" expect="KING RICHARD III &#10;A horse! a horse! my kingdom for a horse!&#10;&#10;CATESBY &#10;&#34;Withdraw, my lord; I'll help you to a horse.&#34;"/>
    <Test find="blah blah" expect="(null)"/>
</TestStrings>
