Testing and software metrics

PHPUnit is the most popular xUnit implementation for PHP that provides a framework for automated
software tests. Except the pure test automation PHPUnit contains a rich set of features like
Code Coverage, Project Mess Detection and Software Metrics. To visualize the generated XML reports
phpUnderControl comes with a set of XSL stylesheets that prepare the output for CruiseControl.

Documentation

phpUnderControl uses the most common documentation tool for PHP projects, PhpDocumentor, to generate
an up to date documentation of the software on every build cycle. Therefore the developers will always get
the latest API documentation of their project. Additionally phpUnderControl extracts the documentation
violations found by the PhpDocumentor and visualizes these as an additional quality report in the user
interface and the project time line of documentation violations.

Coding Standards

With the package PHP_CodeSniffer the PEAR project gave PHP developers a very useful tool to detect coding
standard violations in a project. Since version 1.0.0RC3 it has native support for the Checkstyle XML format
that can be visualized by CruiseControl. PHP_CodeSniffer comes with a variety of pre defined coding standards
like PEAR and ZEND but due to its modular structure you can easily implement a custom rule set or extend one
of the pre defined sets. This development tool assures that the whole project code will remain clean and
consistent.
