    <blockquote> <p>Any tools to generate fancy looking outputs for Project Managers to fawn over?</p> </blockquote> <p>Be careful. A fancy tool for displaying metrics on unit test counts, coverage, code quality metrics, line counts, check-in counts and so on can be dangerous <em>in the hands of some project managers</em>. A project manager (who is not in touch with the realities of software development) can get obsessed with the metrics, and fail to realize that:</p> <ul> <li><p>they don't give the real picture of the project's health and progress, and</p></li> <li><p>they can give a completely false picture of the performance of individual team members.</p></li> </ul> <p>You can get silly situations where a manager gives the developers the message that they should (for example) try to achieve maximal unit test coverage for code where this is simply not warranted. Time is spent on pointless work, the important work doesn't get done, and deadlines are missed.</p> <blockquote> <p>Any rules that should be set - code coverage, or making sure it's unit rather than integration tests.</p> </blockquote> <ul> <li><p>Code coverage is more important for parts of the code that are likely to be fragile / buggy. Don't mandate any benchmark coverage level.</p></li> <li><p>Unit tests versus integration tests depends on the nature and complexity of the system you are building. </p></li> <li><p>Adding lots of unit level tests after the fact is probably a waste of time. It should only be done for class identified as being problematic / needing maintenance work.</p></li> <li><p>Adding integration level tests after the fact is useful, especially if the projects original developers are no longer around. A decent integration test suite helps to increase your confidence that some change does not break important system functionality. But this needs to be done judiciously. A test suite that tests the N-th degree of a website's look and feel can be a nightmare to maintain ... and impediment to progress.</p></li> </ul>

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.
