This dissertation introduces novel techniques for verifying that programs conform to their designs. My Hob system, as described in this dissertation, allows developers to statically ensure that implementations preserve certain specified properties. Hob verifies heap-based properties that can express important aspects of a program's design. The key insight behind my approach is that Hob can establish detailed software design properties--properties that lie beyond the reach of extant static analysis techniques due to scalability or precision issues-by focusing the verification task. In particular, the Hob approach applies scalable static analysis techniques to the majority of the modules of a program and very precise, unscalable, static analysis or automated theorem proving techniques to certain specific modules of that program: those that require the precision that such analyses can deliver. The use of assume/guarantee reasoning allows the analysis engine to harness the strengths of both scalable and precise static analysis techniques to analyze large programs (which would otherwise require scalable, imprecise analyses) with sufficient precision to establish detailed data structure consistency properties, e.g. heap shape properties.
(cont.) A set-based specification language enables the different analysis techniques to cooperate in verifying the specified design properties. My preliminary results show that it is possible to successfully verify detailed design-level properties of benchmark applications: I have used the Hob system to verify user-relevant properties of a water molecule simulator, a web server, and a minesweeper game. These properties constrain the behaviour of the program by stating that selected sets of objects are always equal or disjoint throughout the program's execution.
