Please untar and unzip ostest.tar.gz after downloading it. It will create its own directory. For those of you who are unfamiliar with a the unix archiving utilities tar and gzip, you may use the following command to do this:
gunzip -c ostest.tar.gz |tar -xvf -
You will notice that a directory ballista was created as part of the untar. Change to the Ballista directory.
Execute the tests:
Do not run as root. It is possible that running the test suite as root may corrupt your system.
Answer the questions: When the script first starts it will ask you a couple questions or tell you difficulties that it encountered. If you want robustness failure rates to compare with other systems then hit ENTER when given the choice between ENTER and a percentage.
The package will automatically test every supported POSIX function in your operating system and return the results. NOTE: if a system crash occurs, you must reboot your machine, comment-out the line in the file callTable.all containing the function that caused the crash, and restart the test. (Additional details available)
The testing will take several hours. (We have seen 18-24 hour run times.) The test results are stored in the ../ballista/outfiles directory. In this directory you will notice a file corresponding with each POSIX function that was tested. The format for the function test results is outfile.function_name.param1.param2.... In addition to the function files are the os_results.txt, and os_results.html files, which contain formatted summaries of the os tests.
Important platform specific notes.
Generate stand alone code: Once the tests have been run there will be the option to create stand alone C++ code to reproduce a detected robustness failure. The details for generating code are outlined in the previously mentioned file ../ballista/outfiles/os_results.html. This step is optional but can be useful for bug reports.
Verify Testing: After the Ballista OS Robustness Test Suite completes then you should investigate the associated problems (if any exist). If the Test Suite encounters problems testing a function, it will log the function in .../ballista/outfiles/faillog, display an appropriate message, and skip testing the associated function. Generally these functions will be skipped because:
If after investigating the reason the test suite skipped a function, you make OS specific changes, then the next step is reevaluating the function. The simplest way to perform this evaluation is to rerun the entire test suite. You may however, desire a less time consuming method for checking your changes. One shortcut is temporarily shortening the list of functions listed in the ../ballista/callTable.all file to the functions impacted by your changes. Remember to move ../ballista/outfiles to a temporary name if you want to keep your previous results before rerunning ostest.pl.
Testing is complete: At this point you have:
Compare your results: to reported results on other operating systems. If your results differ from those listed or you are testing an unrepresented OS please consider submiting your results.
