This site hosts the data files used in Evaluating and Improving Fault Localization Techniques. All these files can be generated using scripts in our BitBucket repository, but only over the course of tens of thousands of CPU-hours; we put them here to save future researchers that expense.

For each fault that we analyzed, there are several files:

• A coverage matrix (generated by GZoltar), indicating which tests killed which statements; and an associated file giving the location of each statement in the source code; and an associated log file from GZoltar.
• (possibly) A killmap (generated by Killmap), describing each test's behavior when each mutant is enabled, run with a timeout of 32 hours; and the Major mutation log associated with that killmap; and logged diagnostic information about the killmap generation, which you probably don't need.
• (possibly) Another killmap, again with a 32-hour timeout, but with an occasionally-unsound optimization disabled (optimization discussed in paper).
• (possibly) Another killmap (with the same two log files), run with a 168-hour timeout.

(If a killmap is not present, it means either that it didn't finish within its timeout, or it was unnecessary (because, for example, we didn't need a 168h-killmap since the 32h-killmap completed; or we didn't need an unoptimized killmap because the optimization was sound).

We also provide a .tar.gz file containing all of the information for the artificial faults we generated from Defects4J.

These files are organized like so:

      artificial-faults.tar.gz

You may find the following commands, or variants of them, useful:

• Download all data: wget --recursive --no-parent http://fault-localization.cs.washington.edu/data
• Download only the files for fault Time-3 wget --recursive --no-parent http://fault-localization.cs.washington.edu/data/Time/3
• Download coverage information for all faults wget --recursive --no-parent --accept gzoltar-files.tar.gz http://fault-localization.cs.washington.edu/data
• Add information for artificial faults to Defects4J: wget http://fault-localization.cs.washington.edu/data/artificial-faults.tar.gz && tar xf artificial-faults.tar.gz --directory /path/to/defects4j
