Compatibility Matrix

Description / Features

Emma is Get code coverage for Java project with Emma (an Open Source and robust code coverage tool. By default, Sonar is delivered with JaCoCo and Cobertura but if you prefer Emma you just have to install this plugin and go back to your favorite practice: the test driven development.)

Installation

1. Install the Emma plugin through the Update Center or download it into the SONAR_HOME/extensions/plugins directory
2. Restart the Sonar server

Usage

To make the default code coverage tool:

1. Log in as an administrator
2. Go to Settings > Configuration > General Settings > Java
3. Set the 'sonar.java.coveragePlugin' property to 'emma'

To activate Emma on some projects:

1. Add the 'sonar.java.coveragePlugin=emma' when executing the maven plugin. This can be set in pom.xml or in command line.

2. Or use the 'reuseReports' mode:

   Code Block
   title reuseReports mode language html/xml
   <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis> <!-- Path to the .ec and .em Emma files --> <sonar.emma.reportPath>emmaDir</sonar.emma.reportPath>

    

    

See the Code Coverage by Unit Tests for Java Project tutorial.

Known Limitations

Branch coverage is not calculated as such notion does not exist in Emma.
