To enhance educational effects of Java programming by assisting self-studies of students and reducing teaching loads of teachers, we have proposed a Web-based Java programming learning system using the test-driven development method. In this system, a teacher should register Java programming assign- ments with statements, model source codes, and test codes using a Web browser. Then, a student can submit a test code and an answer source code for each assignment, where both codes are tested auto- matically by a testing tool called Junit at the server. Unfortunately, the current system cannot identify an incomplete test code that does not contain the com- plete test procedures if it has no grammatical error. In this paper, we introduce a code coverage measure- ment tool called Cobertura to detect such a test code by measuring the coverage rate when the submitted test code tests the model source code. We evaluate the effectiveness of our improved system through ex- periments with two simple assignments to 11 students who have studied Java.
