  • Avoid restoring column widths to zero in the Coverage view.

Version 2.1.0 (2012/02/26)

This feature allows so called differential code coverage, a technique proposed by Kaitlin Duck Sherwood in her paper Reducing Code Navigation Effort with Differential Code Coverage.

Version 2.0.0 (2011/12/18)

The first version of EclEmma that is backed by JaCoCo instead of EMMA. This adds several enhancements and new features to EclEmma.

  • Branch Coverage: Branch coverage is shown on the property pages and can be selected in the Coverage view. For the source editors there is a new annotation that marks lines with branches. A new tooltip provides details about branches on a per-line basis.
  • No class file instrumentation: With JaCoCo Java classes are instrumented in-memory only, which means modified class files will not be written to the file system anymore. Therefore the "in-place instrumentation" mode and its disadvantages are not required any more (no re-build required, JAR files can be analyzed). Programs do now launch immediately without delay due to instrumentation of all class files.
  • Source folders can be selected separately even if their class file output location is the same.
