    <p>I am... kind of a beginner on unit testing. </p> <p>I just read some Unit Testing Best Practices. Kind of understand the unit test is meant to prevent changes made on code that will break the application. And we will want create test cases on all the object's public API(getter, methods) to test the object's behavior to see if is as we are expected.</p> <p>So now.. I have a little simple class I need to test:</p> <pre><code>public class Foo{ private readonly string _text; public Foo(string initialText) { this._text = initialText; } public string Text {get;} //Some other methods that will use this Text property to parsing, comparasion etc public string RichTextFormat {....} } </code></pre> <p>In here, this as in the comment, this <strong>Text</strong> property is use a lot of place for parsing, comparasion etc.</p> <p>So I think is very important to ensure the <strong>Text</strong> property returns exactly what I passed inside the constructor.</p> <p>Here is the test cases I wrote...</p> <pre><code>[TestMethod] public void Text_WhenInitialTextIsNull() { string initalizeText = null; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } [TestMethod] public void Text_WhenInitialTextIsEmpty() { string initalizeText = string.Empty; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } [TestMethod] public void Text_WhenInitialTextIsOneLetter() { string initalizeText = "A"; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } [TestMethod] public void Text_WhenInitialTextIsOneSpecialCharacter() { string initalizeText = "!"; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } [TestMethod] public void Text_WhenInitialTextIsOneSentense() { string initalizeText = "Hello, World!"; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } [TestMethod] public void Text_WhenInitialTextIsOneParagraph() { string initalizeText = "Who's the Smartphone Winner? " + System.Environment.NewLine + " On the smartphone front, however, iSuppli put Apple at number one," + " while Strategy Analytics pointed to Samsung. " + System.Environment.NewLine + " According to iSuppli, Apple shipped 35 million smartphones in the first quarter" + " to Samsung's 32 million. Strategy Analytics, however, said Samsung's total was" + " 44.5 million to Apple's 35.1 million. Nokia landed at number three on both lists" + " with 12 percent market share. "; Foo realFoo = new Foo(initalizeText); Assert.AreEqual(initalizeText, realFoo.Text); } </code></pre> <p>I wonder if this... is too heavy?</p>

    1. COIt's too heavy and then some. Why not just check the metrics and see that you've tested 100% of the paths.

    2. COChances are the code paths will end up exercising this property anyway, that said, I do generally write a simple test for setter/getter pairs, but that's me.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
