This fault localization concept uses as an additional context the frequency of the investigated method occurring in call stack instances during the course of executing the failing test cases.

Download a Defects4J-bug
defects4j checkout -p [project] -v [bug][version] -w [output folder]- For example: defects4j checkout -p Lang -v 1b -w /defects4j/Lang_1b
-
Enter bug's directory
cd [output folder]- For example: cd /defects4j/Lang_1b
-
Compile project
defects4j compile -
Run tests
defects4j test -
Set permissions
chmod -R [XXX] ./coverage- For example: chmod -R 777 ./coverage

-
Calculate the FL-scores/ranks:
-
Enter (python) script directory:
cd /python_scripts -
Run main.py
python3 -W ignore main.py --cov-folder=[output folder]/coverage/ --nameMapping=[output folder]/coverage/trace.trc.names --change=./changed_methods/Lang-changes.csv --bugID=[bug]- For example: python3 -W ignore main.py --cov-folder=/defects4j/Lang_1b/coverage/ --nameMapping=/defects4j/Lang_1b/coverage/trace.trc.names --change=./changed_methods/Lang-changes.csv --bugID=1

Result of python scipt:
| bugID | Barinel | Barinel-C | Jaccard | Jaccard-C | ... |
|---|---|---|---|---|---|
| [ID] | [rank] | [rank] | [rank] | [rank] | [rank] |
- Rank(name):
- without
-C: the rank based on "original" (hit) - with
-C: the rank based on call frequency
- without
The result.csv contains the average rank for all bugs.
