OVERVIEW



EclEmma is a free Java code coverage tool for Eclipse, available under the
Eclipse Public License. It brings code coverage analysis directly into the
Eclipse workbench:

 * Fast develop/test cycle: Launches from within the workbench like JUnit test
   runs can directly be analyzed for code coverage.
 * Rich coverage analysis: Coverage results are immediately summarized and
   highlighted in the Java source code editors.
 * Non-invasive: EclEmma does not require modifying your projects or performing
   any other setup.

Since version 2.0 EclEmma is based on the JaCoCo code coverage library. The
Eclipse integration has its focus on supporting the individual developer in an
highly interactive way. For automated builds please refer to JaCoCo
documentation for integrations with other tools.

Originally EclEmma was inspired by and technically based on the great EMMA
library developed by Vlad Roubtsov.

The update site for EclEmma is https://update.eclemma.org/. EclEmma is also
available via the Eclipse Marketplace Client, simply search for "EclEmma".


FEATURES


LAUNCHING

EclEmma adds a so called launch mode to the Eclipse workbench. It is called
Coverage mode and works exactly like the existing Run and Debug modes. The
Coverage launch mode can be activated from the Run menu or the workbench's
toolbar:



Simply launch your applications or unit tests in the Coverage mode to collect
coverage information. Currently the following launch types are supported:

 * Local Java application
 * Eclipse/RCP application
 * Equinox OSGi framework
 * JUnit test
 * TestNG test
 * JUnit plug-in test
 * JUnit RAP test
 * SWTBot test
 * Scala application


ANALYSIS

On request or after your target application has terminated code coverage
information is automatically available in the Eclipse workbench:

 * Coverage overview: The Coverage view lists coverage summaries for your Java
   projects, allowing drill-down to method level.
 * Source highlighting: The result of a coverage session is also directly
   visible in the Java source editors. A customizable color code highlights
   fully, partly and not covered lines. This works for your own source code as
   well as for source attached to instrumented external libraries.

Additional features support analysis for your test coverage:

 * Different counters: Select whether instructions, branches, lines, methods,
   types or cyclomatic complexity should be summarized.
 * Multiple coverage sessions: Switching between coverage data from multiple
   sessions is possible.
 * Merge Sessions: If multiple different test runs should be considered for
   analysis coverage sessions can easily be merged.


IMPORT/EXPORT

While EclEmma is primarily designed for test runs and analysis within the
Eclipse workbench, it provides some import/export features.

 * Execution data import: A wizard allows to import JaCoCo *.exec execution data
   files from external launches.
 * Coverage report export: Coverage data can be exported in HTML, XML or CSV
   format or as JaCoCo execution data files (*.exec).
