EclEmma 3.1.2Java Code Coverage for EclipseOverview Installation User Guide Support Resources Developer Information Research JaCoCo Change Log License Contact GitHub HomeOverviewEclEmma is a free Java code coverage tool forEclipse, available under theEclipse Public License. It bringscode coverage analysis directly into the Eclipse workbench:Fast develop/test cycle: Launches from within the workbench likeJUnit test runs can directly be analyzed for code coverage.Rich coverage analysis: Coverage results are immediately summarizedand highlighted in the Java source code editors.Non-invasive: EclEmma does not require modifying your projects orperforming any other setup.Since version 2.0 EclEmma is based on theJaCoCo codecoverage library. The Eclipse integration has its focus on supporting theindividual developer in an highly interactive way. For automated builds pleaserefer to JaCoCodocumentation forintegrationswith other tools.Originally EclEmma was inspired by andtechnically based on the greatEMMA librarydeveloped by Vlad Roubtsov.

FeaturesLaunching
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.
