For this project, you can form a group and the maximum number of

members in one group is 2. You should find your teammate by

yourself. You can also work on it individually.

In this project, you will implement Spectrum-Based Fault Localization (SBFL) for

real-world Java programs with unit tests. Specifically, you will calculate

suspiciousness values of source code elements by using the 4 formulae in Page 9

of Module 6 slides.

The program you will analyze is JFreeChart (https://github.com/jfree/ifreechart)

and you don't need to collect its coverage information. Instead, the coverage data

has been provided in D2L. You just need to write your own program by using any

programming language (e.g., Java, Python, C++, etc.) to process the coverage

data and calculate the suspiciousness values based on the 4 SBFL formulae.

Explanation of the coverage data:

1. The coverage data (CoverageData.tar) is in the module "Course Project" in D2L

as follows.

2. You need to uncompress the .tar file firstly and then you

will find multiple .gz files. For each .gz file, you will find that the

first line represents one test case and other lines represent the

source code methods covered by this test. The example is as

follows, and “true” just represents that the test case is a

passed test.

Please note that the tests and source code methods are

represented by Java bytecode. You can learn Java bytecode by

yourself if you are interested (https://www.irebel.com/blog/java-

bytecode-tutorial). However, it is not required for this project.

You just need to view them as unique tests and source code

elements (source code methods)./nTest case

3. You should write code to read all .gz files and convert the data

required for SBFL.

4. There are no failed tests in the data. But you should

manually set some tests as failed tests.

Final Submission

1. Your code to process coverage data and to implement the 4

SBFL formulae in Page 9 of Module 6 slides.

Please note that you should also provide one command to

execute your program. The input of your program should

be the coverage data and the output should be the ranking

list of source code methods with the suspiciousness values.

2. The final list of source code methods with the suspiciousness

values

3. One-page report to describe how you complete this project.
