A Ballista Retrospective
Software Robustness Testing A Ballista Retrospective Phil Koopman [email protected] http://ballista.org With contributions from: Dan Siewiorek, Kobey DeVale John DeVale, Kim Fernsler, Dave Guttendorf, Nathan Kropp, Jiantao Pan, Charles Shelton, Ying Shi Institute for Complex Engineered Systems Overview Introduction • APIs aren’t robust (and people act as if they don’t want them to be robust!) Top 4 Reasons people give for ignoring robustness improvement • “My API is already robust, especially for easy problems” (it’s probably not) • “Robustness is impractical” (it is practical) • “Robust code will be too slow” (it need not be) • “We already know how to do it, thank you very much” (perhaps they don’t) Conclusions • The big future problem for “near-stationary” robustness isn’t technology -- it is awareness & training 2 Ballista Software Testing Overview SPECIFIED INPUT RESPONSE BEHAVIOR SPACE SPACE ROBUST SHOULD VAL I D OPERATION WORK INPUTS MO DULE REPRODUCIBLE UNDEFINED UNDER FAILURE TEST SHOULD INVALID INPUTS UNREPRODUCIBLE RETURN FAILURE ERROR Abstracts testing to the API/Data type level • Most test cases are exceptional • Test cases based on best-practice SW testing methodology 3 Ballista: Test Generation (fine grain testing) Tests developed per data type/subtype; scalable via composition 4 Initial Results: Most APIs Weren’t Robust Unix & Windows systems had poor robustness scores: • 24% to 48% of intentionally exceptional Unix tests yielded non-robust results • Found simple “system killer” programs in Unix, Win 95/98/ME, and WinCE -

Plaintiff Xinuos, Inc. (“Xinuos”), for its Complaint against Defendants International Business Machines Corp. (“IBM”) and Red Hat, Inc. (“Red Hat”) alleges on knowledge as to itself, its own acts and facts known to it and reasonable inferences therefrom, and on information and belief as to all other matters, as follows: 2. This case is simple. IBM and Red Hat conspired to illegally corner a market and crush competition. First, IBM stole Xinuos’ intellectual property and used that stolen property to build and sell a product to compete with Xinuos itself. Second, stolen property in IBM’s hand, IBM and Red Hat illegally agreed to divide the relevant market and use their growing market powers to victimize consumers, innovative competitors, and innovation itself. Third, after IBM and Red Hat launched their conspiracy, IBM then acquired Red Hat to solidify and make permanent their scheme. Fourth, IBM has been misleading its investors by falsely claiming all infringement claims against IBM regarding the copied code have been waived. 3. IBM and Red Hat have engaged in this well-worn, anticompetitive conduct in order to corner the market for operating system software that companies rely on to use servers. -
