Contents

• index.html: directs to the overview web page
• LICENSE-results.txt: specifies the license
• README-results.txt: this file
• results-validated/: results of validation runs
• results-verified/: results of test-generation runs and aggregated results

The folder results-validated/ contains the results from validation runs:

• *.results.txt: TXT results from BenchExec
• *.xml.bz2: XML results from BenchExec
• *.logfiles.zip: output from tools
• *.json.gz: mapping from files names to SHA 256 hashes for the file content

The folder results-verified/ contains the results from test-generation runs and aggregated results:

• index.html: overview web page with rankings and score table

• design.css: HTML style definitions

• *.results.txt: TXT results from BenchExec

• *.xml.bz2: XML results from BenchExec

• *.fixed.xml.bz2: XML results from BenchExec, status adjusted according to the validation results

• *.csv: CSV results

• *.fixed.csv: CSV results, status adjusted according to the validation results

• *.logfiles.zip: output from tools

• *.json.gz: mapping from files names to SHA 256 hashes for the file content

• *.xml.bz2.table.html: HTML views on the detailed results data as generated by BenchExec’s table generator

• <tester>*.table.html: HTML views of the full benchmark set (all categories) for each tester

• META_*.table.html: HTML views of the benchmark set for each meta category for each tester, and over all testers

• <category>*.table.html: HTML views of the benchmark set for each category over all testers

• *.xml: XML table definitions for the above tables

• results-per-tool.php: List of results for each tool for review process in pre-run phase

• <tester>.list.html: List of results for a tool in HTML format with links

• quantilePlot-*: score-based quantile plots as visualization of the results

• quantilePlotShow.gp: example Gnuplot script to generate a plot

• score*: accumulated score results in various formats

The hashes of the file names (in the files *.json.gz) are useful for

• validating the exact contents of a file and
• accessing the files from the witness store.
