A random testing strategy can be effective at finding faults, but may leave some routines entirely untested if it never gets to call them on objects satisfying their preconditions. This limitation is particularly frustrating if the object pool does contain some precondition-satisfying objects but the strategy, which selects objects at random, does not use them. The extension of random testing described...
Several static analysis techniques, e.g., symbolic execution or scope-bounded checking, as well as dynamic analysis techniques, e.g., specification-based testing, use constraint solvers as an enabling technology. To analyze code that manipulates structurally complex data, the underlying solver must support structural constraints. Solving such constraints can be expensive due to the large number of...
The cache utilization seriously impacts on program performance, whereas the cache behavior is transparent to developers so that they cannot get opportunity to optimize their programs by reducing cache miss rates. This paper introduces a useful instrumentation tool, Cachebit, which is built with Crossbit - a dynamic binary translation (DBT) framework with intermediate instruction layer. Cachebit simulates...
