 Priority:  normal            |  Milestone:  Awaiting Review
Component:  Build/Test Tools  |    Version:  trunk

 The current PHPUnit configuration has been configured as follows:
 {{{
 <filter>
     <whitelist processUncoveredFilesFromWhitelist="true">
         <directory suffix=".php">src</directory>
     </whitelist>
 </filter>
 }}}

 This means that all the files in the `src/` folder are included when
 running a coverage report.

 Reference to documentation:
 https://phpunit.de/manual/current/en/code-coverage-analysis.html#code-
 coverage-analysis.whitelisting-files

 > Please note that the loading of sourcecode files that is performed when
 processUncoveredFilesFromWhitelist="true" is set can cause problems when a
 sourcecode file contains code outside the scope of a class or function,
 for instance.


 Changing it to the following configuration allows for coverage to be run.

 {{{
 <filter>
     <whitelist addUncoveredFilesFromWhitelist="true">
         <directory suffix=".php">src</directory>
     </whitelist>
 </filter>
 }}}
