An automated software testing and validation system allows testing of a software application under test (SAUT) regardless of the dynamic nature of the SAUT. An abstracted set of hierarchal or linear objects model certain regions of the SAUT. Automated test scripts utilize theses regions to intuitively navigate and identify potions of the SAUT to automate. The scripts can also access specific SAUT elements contain within each defined region. These elements can then be used to invoke actions or verify outputs there from. The system uses a set of rich identification rules embodied in the system which allow the user to configure the identification of any element within the abstracted region. The rules are customizable to allow the user to configure the desired level of loose coupling between the automated scripts and the target element to adapt the scripts to the nature of the SAUT.

A system and method for replacing an original linear object with an updated linear object. In a flash memory or other memory device storing groups of data objects, in replacing a linear object with an updated linear object of the same size, the present invention overwrites the original linear object in the same memory space as the original version. As a result, updating the data requires erasing and writing of the block of flash memory cells where the data object is stored. A copy of the original linear object is stored so that the original version of the linear object is available for undoing the update and / or facilitating recovery if the updated linear object becomes corrupted.

A controller design for switching between m linear multivariable controllers each of whom stabilizes a linear plant has been presented. A Youla-Kucera factorization was exploited in the interest of obtaining a closed-loop system that is exponentially stable for any switching signal σ(t) in the absence of plant model uncertainty. Robustness to practical model uncertainty was also considered and lower and upper bounds on the tolerable magnitude of unstructured additive plant uncertainty were presented. Numerical example demonstrated that the two controller degrees of freedom in the proposed controller design could be used to separately modify the closed-loop steady-state (with respect to σ(t)) performance and the switching transients.
