VSTS doesn't have a pure set of Test Driven Development features, but using the built-in refactoring support for C# you are able to get a good Test Driven Development experience in VSTS 2005. Test Driven Development is a methodology we greatly believe in at Microsoft, new Test Driven Development specific features might show up in future releases.
Here’s how you can use refactoring to generate shipping code from a Unit Test in VSTS. Let’s say, I need to test class A that has method “string GetData()”. I start from writing the test for it:
[
TestClass]
public class ATest
{
[TestMethod]
public void GetDataTest()
{
A a = new A();
string s = a.GetData();
Assert.AreEqual("my data", s, "Wrong data returned!");
}
}
I want to generate the A.GetData from this test. Well, since class A does not exist yet, I create it manually as:
public class A
{
}
All I have to do now is right-click a.GetData() in my test and select “Generate Method Stub” from context menu:
It generates the following code:
public class A
{
internal string GetData()
{
throw new Exception("The method or operation is not implemented.");
}
}
Now I can run the test and make sure it fails. Then I will implement GetData, run my test and fix the code, until the test passes.
