• Clover will only report a line that contains Groovy's safe operator as covered if the check evaluated to both true and false.
• Clover also supports filtering specified Groovy methods.

Clover-for-Grails Plugin for Grails 1.3.7

Clover 3.1 incorporates a plugin for the Grails web application development framework supporting Grails version 1.3.7. Grails project developers can test their Groovy code using Clover to generate coverage reports.

The Clover-for-Grails plugin is very easy to install and upgrade, with multiple installation options that can be issued from a single Grails command. Upgrading is as easy as reinstalling the Clover-for-Grails plugin.

You can configure the Clover-for-Grails plugin on the command line or by including Clover-for-Ant-based (Gant) instructions directly inside the BuildConfig.groovy file.
