Comment (by dd32):

 Did lots more digging, and is definitely caused by the extension or PHP
 internals and isn't a WordPress nor PHPUnit bug.

 https://github.com/mkoppanen/imagick/issues/147#issuecomment-212297265
 I'll copy it here for future reference:
 > The debug log from that PHPUnit run had a huge number of issues, but
 unfortunately it's definitely all caused by the Imagick extension (or
 potentially a bug within PHP itself). The reason the log was so full was
 that once a Imagick exception is triggered, every PHP warning thereafter
 is thrown as a ImagickException (where it shouldn't be thrown at all).
 >
 > Here's a minimal script to reproduce it:
 >
 > {{{
 > <?php
 > error_reporting( E_ALL ); ini_set( "display_errors", true );
 >
 > try {
 >        $f = new Imagick( 'http://any/url/here' );
 > } catch( Exception $imagick_exception ) {
 >        var_dump( compact( 'imagick_exception' ) );
 > }
 >
 > getimagesize( "something here" );
 > }}}
 >
 > What you'd expect to see here is the imagick_exception data followed by
 a PHP Warning, instead you get the imagick_exception data followed by a
 PHP Fatal:
 >
 > {{{ Fatal error: Uncaught ImagickException: getimagesize(something
 here): failed to open stream: No such file or directory}}}
