Version 3.2 of PHPUnit is shaping up nicely. In this blog posting I want to highlight another aspect of PHPUnit's new Project Mess Detector feature set. Duplicate code can be hard to find, especially in a large project. Johann-Peter Hartmann of MAYFLOWER GmbH recently implemented Copy & Paste Detection for PHPUnit's growing set of features that extends its usage scenarios beyond "just unit testing" to a one-stop solution for quality assurance in PHP-based projects. Here is an example of how PHPUnit 3.2 will report code duplication:
__toString(), $this->drawnGradients, true ) )
{
$gradient = $this->dom->createElement( 'linearGradient' );
$gradient->setAttribute( 'id', 'Definition_' . $color->__toString() );
$this->defs->appendChild( $gradient );
// Start of linear gradient
$stop = $this->dom->createElement( 'stop' );
$stop->setAttribute( 'offset', 0 );
$stop->setAttribute(
'style',
sprintf( 'stop-color: #%02x%02x%02x; stop-opacity: %.2F;',
$color->startColor->red,
$color->startColor->green,
]]>
