    <p>I've been in the process of creating a test suite for a project, and while I realize getting 100% coverage isn't <em>the</em> metric one should strive to, there is a strange bit in the code coverage report to which I would like some clarification. </p> <p>See screenshot:</p> <p><img src="https://i.stack.imgur.com/cZfQl.png" alt="enter image description here"></p> <p>Because the last line of the method being tested is a <code>return</code>, the final line (which is just a closing bracket) shows up as never being executed, and as a consequence the whole method is flagged as not executed in the overview. (Either that, or I'm not reading the report correctly.)</p> <p>The complete method: </p> <pre><code>static public function &amp;getDomain($domain = null) { $domain = $domain ?: self::domain(); if (! array_key_exists($domain, self::$domains)) { self::$domains[$domain] = new Config(); } return self::$domains[$domain]; } </code></pre> <p>Is there a reason for this, or is it a glitch?</p> <p>(Yes, I read through <a href="https://stackoverflow.com/questions/7074022/how-to-get-100-code-coverage-with-phpunit">How to get 100% Code Coverage with PHPUnit</a>, different case although similar.)</p> <p>Edit: </p> <p>Trudging on through the report, I noticed the same is true for a <code>switch</code> statement elsewhere in the code. So this behaviour is at least to some extent consistent, but baffling to me none the less.</p> <p>Edit2:</p> <p>I'm running on: PHPUnit 3.6.7, PHP 5.4.0RC5, XDebug 2.2.0-dev on a OS X</p>

    1. CO@Lieven The return is the last line of a method, but I posted the complete method as well.

    2. COThe only strange bit I see is the & b to return a reference. In PHP 5.x all objects are references. I don't think this would trip up Xdebug, and it works for edorian, but you may want to try removing it.

    3. CO@DavidHarkness Perhaps, but as I mention in my edit, the same occurs for a `switch` statement as well. All cases end in a `break` so the closing bracket is supposedly skipped. Just seems odd to me that the bracket is considered a line of runnable code at all.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
