  <mainDescription>&lt;p>&#xD;
    Every asset in a product line development effort should be validated, preferably before it is put into widespread use.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    A product line organization produces assets of many types besides code. Architectures and requirements models are not&#xD;
    as executable as the code but do have standardized syntax. Scoping documents, business cases, and other text documents&#xD;
    do not have a standard syntax. A variety of techniques are required to validate each of these assets.&#xD;
&lt;/p>&lt;br />&#xD;
&lt;p>&#xD;
    Techniques include both static and dynamic activities. These techniques have typically gone under the names:&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    &lt;strong>review&lt;/strong> - Investigates the form and some of the substance of an artifact by human reading of the&#xD;
    artifact.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    &lt;strong>inspection&lt;/strong> - Investigates the semantics of the artifact by human reading or automatically applying a&#xD;
    set of rules. Design pattern recognition and some architecture conformance tools are examples.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    &lt;strong>test&lt;/strong> - Investigates the quality of an asset by automatic means. Executing a program or running a&#xD;
    simulation of an architecture are examples.&#xD;
&lt;/p>&lt;br />&#xD;
&lt;p>&#xD;
    A product line organization should employ all three of these techniques. In the testing tasks described here we will&#xD;
    also show how a testing perspective can be applied no matter which of the three techniques are used.&#xD;
