- Use ASM byte-code manipulation framework [3] to build an automated coverage collection tool that can capture the statement coverage for the program under test. Then, apply your tool to 10 real-world Java projects (>1000 lines of code) with JUnit tests (>50 tests) from GitHub [1]/SourceForge [2] (see a list in the appendix) to collect the statement coverage for its JUnit tests. Note that your tool should (1) use Java Agent [12] to perform on-the-fly code instrumentation, and (2) be integrated with the Maven build system [18] so that your tool can be triggered by simply changing the pom.xml file of the project under test. You are also highly recommended to trace coverage for each single JUnit test by capturing the test start/end events.
