[C#] 使用 Visual Studio Unit Testing Framework

The Visual Studio Unit Testing Framework describes Microsoft's suite of unit testing tools as integrated into Visual Studio 2005 and later.

Example: (Member Single Round Match 505 Round 1 - Division II, Level One)

Step 1: Add a test.

using Microsoft.VisualStudio.TestTools.UnitTesting;
using AlgorithmMatch;

namespace AlgorithmMatchTest {

[TestClass]
public class SentenceCapitalizerInatorTest {
  public TestContext TestContext { get; set; }

  [TestMethod]
  public void RunSanityTest() {
    var Q = new SentenceCapitalizerInator();

    {
      var P = "hello programmer. welcome to topcoder.";
      var A = "Hello programmer. Welcome to topcoder.";
      Assert.AreEqual(A, Q.fixCaps(P), false);
    }
  }
}

}  // namespace AlgorithmMatchTest

Step 2: Run all tests and see if the new one fails
The new test fails.

Step 3: Write some code

using System;
using System.Text;

namespace AlgorithmMatch {

public class SentenceCapitalizerInator {
  public String fixCaps(String paragraph) {
    return paragraph;
  }
}

}  // namespace AlgorithmMatch

Step 4: Run all tests and see if the new one fails.
Fails. We should implement fixCaps() method correctly.

Step 5: Write some code

using System;
using System.Text;

namespace AlgorithmMatch {

public class SentenceCapitalizerInator {
  public String fixCaps(String paragraph) {
    var result = new StringBuilder();
    bool is_began = true;
    foreach (char c in paragraph) {
      if (is_began && char.IsLetter(c)) {
        result.Append(char.ToUpper(c));
        is_began = false;
      }
      else if (c == '.') {
        result.Append(c);
        is_began = true;
      } else {
        result.Append(c);
      }
    }
    return result.ToString();
  }
}

}  // namespace AlgorithmMatch

Step 6: Run the automated tests and see them succeed.
Passed.

Step 7: Repeat.
We may add more tests from system test dataset.
