Automated Testing for Programmable Logic Control Systems

Developing real-time, automated testing for mission-critical programmable logic controller (PLC)-based control systems has been a challenge for many scientists and engineers. Some have elected to use customized software and hardware as a solution, but that can be expensive and time consuming to develop. Reginald Howard shows you a way to integrate a suite of commercially available, off-the-shelf tools and hardware to develop a scalable, Windows-based testing platform that's capable of performing an array of different tests including, but not limited to, black box, destructive, regression, and system security testing. He describes the use of the Jelinski-Morana statistical model for determining expected results from automated tests.

The Awful Truth About Logic-Testing

This presentation covers conditions and expressions; truth tables; normal form patterns; modified condition/decision coverage; constructing an MC/DC test set; tools for checking MC/DC coverage; unique cause coverage; basic unique cause design; and logic coverage references.

Analyzing Web Application Errors

This presentation focuses on the characteristics of Web application errors to derive key issues to consider in analyzing and reproducing errors. Learn how to isolate application errors from configuration and technical support issues. Explore effective techniques to make errors reproducible. Examples of common and uncommon Web application error types are provided.

Solid Software: Is it Rocket Science?

While we can't guarantee that our software will never fail, we can take serious steps to reduce the risk. The toughest kind of system to build involves safety-critical software where the reliability requirements are extremely strict-and whose failure puts lives in jeopardy. Shari Lawrence Pfleeger looks at what "solid software" means, and explores ways we can achieve it. She examines solid software within the context of the proposed National Missile Defense System.
