Use ASM byte-code manipulation framework to build an automated coverage collection tool that can capture the statement coverage for the program under Junit test.
- use Java Agent to perform on-the-fly code instrumentation.
Import project to Intellij Idea, then build artifact. The name of output artifact is "agent.jar"
