copied!<p>There are four possible problems here;</p> <p><strong>The namespaces in your code are dividing your classes too finely.</strong> if you have, for example;</p> <pre><code>using MyCompany.Drawing.Vector.Points; using MyCompany.Drawing.Vector.Shapes; using MyCompany.Drawing.Vector.Transformations; </code></pre> <p>consider collapsing them to the single <code>MyCompany.Drawing.Vector</code> namespace. You probably aren't gaining by dividing too much. Visual Studio Code Analysis/FxCop has a rule for this, checking the number of classes in a namespace. Too few and it will warn you.</p> <p><strong>You are putting too many tests into the same class.</strong> If you are referencing <code>System.Data</code>, <code>System.Drawing</code>, and <code>System.IO</code> in the same class, consider writing more atomic tests -- some which access databases, some which draw images, and some which access the file system. Then divide each type across three test classes.</p> <p><strong>You are writing tests which do too much.</strong> If you are referencing a lot of namespaces, your tests may be coupling too many features together. This kind of coupling can often be buggy, so try to break big, wide-ranging functions into smaller parts, and test these in seperate files. </p> <p><strong>Many are redundant.</strong> Are they all used, or are they just copy-pasted from other files. Right-click on the code editor and choose from the 'Organise Using' options to remove unused statements.</p>
