Question

在我运行测试之前，我已将代码设置为如下所示：

private bool ValidateTestOne(EntityModel.MultiIndexEntities context)
{
    if (context.SearchDisplayViews.Count() != expectedSdvCount)
    {
        Assert.Fail("Search Display View count was different from what was expected");
    }

    if (sdv.VirtualID != expectedSdVirtualId)
    {
        Assert.Fail("Search Display View virtual id was different from what was expected");
    }

    if (sdv.EntityType != expectedSdvEntityType)
    {
        Assert.Fail("Search Display View entity type was different from what was expected");
    }

    return true;
}

这也会返回正确的路径，告诉我测试是通过还是失败。从那时起，经过一些建议，我改变了我的代码，看起来如下：

private bool ValidateTestOne(EntityModel.MultiIndexEntites  context)
{
    Assert.AreEqual(expectedEntityCount, context.Entities.Count(),
        "Entity Count was different from what was expected");

    return true;
}

我对使用新Assert.AreEqual的想法是，它仍将返回true或false，具体取决于它是通过还是失败。但是现在我的测试总是返回true，因为如果我的测试失败了，我就无法解决问题。

所有这些都是通过在我的主要测试方法中调用以下行来确定的：

Assert.IsTrue(test4PassFail = ValidateTest("4.4"), "Test 4 ");

有没有办法可以修改我的新代码以返回真或假，而不必回复我的旧代码？

Answer 1

而不是return true;，您可以Assert.AreEqual(expectedEntityCount, context.Entities.Count()");。

这将是你的失败/通过。你不需要做出回报。但事实上，你一直都在返回true。

[TestClass]
public class Tests
{
     [TestMethod]
     private void ValidateTestOne(EntityModel.MultiIndexEntites  context)
     {
          Assert.AreEqual(expectedEntityCount, context.Entities.Count(), "Entity Count was different from what was expected");
     }
}

您需要遵循MSTest的测试方式。您的类需要具有[TestClass]属性，并且您的方法需要[TestMethod]。测试类中的方法都是无效的。无论断言如何，您的方法都返回true。 VS允许您添加测试项目和测试类以支持您的代码。它会为您添加适当的属性。

[TestClass]
public class Tests
{
   [TestMethod]
   public void DriveInfoTest()
   {
       // set up
       DriveUnit uut = new DriveUnit();

       // run
       var result = uut.GetInfo();


      // verify
      Assert.IsNotNull(result, "Get Info did not return an object.");
   }

}

在第一个中你总是返回true，因为那是你设置它返回的内容。

如果是else语句，你应该考虑将它们嵌套

private bool ValidateTestOne(EntityModel.MultiIndexEntities context)
  {
     if (context.SearchDisplayViews.Count() != expectedSdvCount)
        {
              Assert.Fail(" Search Display View count was different from what was expected");
//does it return true or false?
//return true or false

        } else if (sdv.VirtualID != expectedSdVirtualId){

             Assert.Fail(" Search Display View virtual id was different from what was expected");

//again true or false?

        } else if(sdv.EntityType != expectedSdvEntityType) {
           Assert.Fail(" Search Display View entity type was different from what was expected");
//true or false?

        }

  }

即使测试失败，C＃test总是返回true
