Testing: Jacoco Reports

How to interpret the reports (red, yellow, green)

How to read the test coverage reports

• If any line of code is red, that means it is not tested at all—it is being missed by line coverage
• If a line of code is yellow, it means there are multiple ways to execute the line.
  • it may have an if/else, or a boolean expression involving && or ||, and thus there are multiple paths through the code (multiple branches).
  • Yellow means it is being missed by branch coverage; some branches are covered, and others are not.
  • Think about the multiple paths through the code and be sure your tests are coverage all of them.
