    <p>I've just started using PHPUnit and am wondering if there is a build in way of dumping the contents of a variable? </p> <p>The use-case being that since I am already talking to the code I'm developing, I can use PHPUnit not only to test the stability of that code but also to output debug info while being in development.</p> <p>I know xdebug can fill this gap for me, but sometimes it's just easier to dump some info in the output rather than fiddling with my IDE debugger, which is more useful for tracing back the cause of a bug.</p> <p>I know I can just do a regular var_dump, I'm simply wondering if PHPUnit has an interface for this.</p> <p>Thanks!</p> <p><strong>Edit:</strong></p> <p>Decided to hack it together following David's answer.</p> <p>By no means a perfect solution, but it does the job for 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.
