Generating Clover Reports
Install the Clover-for-Grails plugin
Install the Clover-for-Grails plugin by running the following Grails command in the root of your Grails project directory.
grails install-plugin clover
For more installation options or to upgrade this plugin, please see Clover-for-Grails Installation Guide.
Generating a basic Clover coverage report
To generate a basic Clover code coverage report, you need to add the Clover option -clover.on to the grails test-app command line target for running unit tests against your Grails project.
grails test-app -clover.on -clover.view
Adding the Clover option -clover.view to this Grails command makes the report open in a browser window immediately after generation. If you omit this command line option, Clover will generate a report that you can then open manually.
Passing the location of your clover.license file to the grails command line
If you have not placed your clover.license file within your Grails project or user home directory (as indicated in the Installation Guide), you can pass the license file's location to the grails command line by adding the Clover option -clover.license.path=/path/to/clover.license:
grails test-app -clover.on -clover.license.path=/path/to/clover.license
On Windows platform you must put the "-clover.license.path=c:\path\to\clover.license" in double quotes, otherwise it won't work (it's a Grails feature).
Troubleshooting
If you find that Clover-for-Grails runs out of memory, try increasing the Grails PermGen allocation by either setting the JAVA_OPTS environment variable:
Linux/UNIX/Mac OS X:
export JAVA_OPTS="-XX:MaxPermSize=192m"
Windows:
set JAVA_OPTS="-XX:MaxPermSize=192m"
Alternatively, you can define this variable in the startGrails (Linux/UNIX/Mac OS X) or startGrails.bat (Windows) script in the <Grails Home Directory>/bin directory.
