Jacoco Test Coverage Comparison Tool

This repository extends the test coverage report of Jacoco by creating a comparison report. The comparison report shows the differences and similarities between the test coverage of two different sets of test cases.

Instructions

To genrate the coverage report follow the bellow steps:

• Run your test cases using Jacoco to generate the coverage report for each individual test suite. This will generate some intermediate results in a .exec file. Currently the project supports only two sets of test suites.
• Create a folder as your source folder.
• Create a "bin" directory under your source folder, and put your compiled source (jar or class files) inside that "bin" directory.
• Put your exec files under the source folder.
• Edit the configuration in the report.conf file inside the project root folder.
  • source: The absolute path to your source folder.
  • reports: The absolute path to the directory where the generated report files will be copied to
  • execfile[0]: The path to your first intermediate data file ex. jacoco1.exec
  • execfile[1]: The path to your second intermediate data file ex. jacoco2.exec
  • packages [optional] : The comma separated name of packages to be included in the report.
  • titles [optional] : The comma separated title of test suites, to be used in the coverage report.
• Run the report generation script by running ./report.sh
• The generated HTML reports, will be saved inside the reports directory
