MSTest

MSTest is the testing framework created by Microsoft that has been included in specific versions of Visual Studio since 2005. MSTest sparks many heated discussions among developers. When all is said and done, MSTest is similar to many of the other unit-testing frameworks, with a slightly different syntax. It has been my experience that the tests run slower, but you should make your own call.

{
    [TestMethod]
    public void Should_Truncate_Text_Over_Five_Characters_Long()
    {
 string textToTruncate = “This is my text”; string expected = “This ..”; string actual = HTMLHelper.Truncate(textToTruncate, 5); Assert.AreEqual(expected, actual); } [TestMethod] public void Should_Not_Truncate_Text_When_No_Length_Is_Passed_In() { string textToTruncate = “This ...
