EclEmma-Java Code Coverage for Eclipse

Brief introduction

First, we look at the official website of the plugin description:

I. Overview
EclEmma IS A as Free Java code coverages Tool for Eclipse, the Available an under at The Eclipse Public License It Brings code coverages the Analysis Directly INTO at The Eclipse Workbench:.
  EclEmma Eclipse is free Java code coverage tool, available under the Eclipse Public License. Code coverage analysis will be introduced directly into the Eclipse workbench:
Fast Develop / the Test Cycle: Launches the WITHIN like JUnit the Test at The Workbench runs Analyzed for code CAN BE Directly from coverages.
  Rapid development / test cycle: direct analysis JUnit test run start in the table for code coverage.
Rich coverage analysis: Coverage results are immediately summarized and highlighted in the Java source code editors.
  Rich coverage analysis: Summary and immediately coverage results are highlighted in the Java source code editor.
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.

Second, characteristics

1. EclEmma added a so-called startup mode for the Eclipse workbench. It is called Coverage mode, it works exactly the same as the conventional and Run Debug mode. Can activate the "cover" start-up mode from the toolbar "Run" menu or table:
   
   simply launch the application or the unit test coverage information can be collected in the Coverage mode. Supports the following startup types:
   (1) local Java application
   (2) Eclipse / RCP applications
   (3) Equinox OSGi framework
   (4) JUnit Test
   (5) TestNG test
   (6) JUnit plug-in test
   (7) JUnit RAP test
   ( 8) SWTBot test
   (9) Scala application

2. A request or upon termination of the target application, Eclipse workbench will automatically provide code coverage information:
   (1) coverage Overview: "Coverage" view lists the coverage summary Java project, to allow in-depth method level.
   (2) Source Highlight: the results of the session are covered Java source code editor directly visible. Customizable color highlighted code completely, and the line portion uncovered. This applies to your own source code and the source code has been added to detect external libraries.
   Other features to support your test coverage analysis:
   (1) different counters: select whether an instruction should be aggregated, branch, line, method, type, or circle complexity.
   (2) covering the plurality of sessions: the coverage data can switch between multiple sessions.
   (3) Merge sessions: If you want to consider several different tests run for analysis, you can easily merge session.

3. Although EclEmma primarily for test run and analyze the Eclipse workbench and design, but it provides a number of import / export capabilities.
   Perform data import: Import Wizard allows JaCoCo start from the outside .exec perform data files.
   Export coverage report: Coverage data can be HTML, XML or CSV format export, can also be exported as JaCoCo perform data file ( .exec).
