The scenario is particularly acute when dealing within the safety critical domain. This paper will seek to highlight how UML and in particular, improvements introduced by SysML can aid the testing process in terms of verification, validation and simulation of software, firmware and mechanical systems. This paper will highlight how UML and SysML constructs can aid testing and is based on many years experience of building and testing systems as well as the experience gained by client companies during consultation. It will highlight on a practical basis how clients have integrated testing into their UML/SysML models to improve their processes and products.  \nIntroduction  \nThe UML is the de facto standard for software development, and allows the user to model their system in terms of structural analysis through class, package, composite structure, object, component, and deployment diagrams. UML also allows the user to model the behavior of a system through state machine, activity, use case, sequence, communication, timing, and interaction overview diagrams. While UML could be used to model systems SysML can more effectively aid the understanding of structure of a system through block definition, package, internal block, instance, parametric, and requirement diagrams. System behavior can further be enlightened investigated and illuminated through state, activity, use case, and sequence diagrams. In particular the use of SysML notation aids the Systems Engineer in construction of systems, system integration and unit tests, as well as providing critical system performance details needed in the handover to software engineers. If we look at each one of these diagrams in turn we can understand what benefits each holds for the Systems Engineer when designing atestable system. See OMG (2007b) for the SysML specification, Hause (2006a) for a summary, and Friedenthal et al (2008), Korff (2008), and Holt (2008) for books on SysML.  \nRequirements Diagram. The requirements diagram within SysML is a cross cutting construct that allows the system designer to both document system requirements and show the interrelationship that exist between requirements, e.g. refine, verify, satisfy, test case, etc. and other system artifacts (Hause, 2006b) .  \nThe Safety Integrity Level (SIL) concept was created in order to quantify the safety requirements of a specific components or set of components in a safety related system (IEC, 2002) . Specifically, a SIL is the indicator of the likelihood of meeting required safety features. When we are developing a safety critical system, say to SIL 3, a key requirement is to have full requirements coverage. The requirements diagram can be used not just by the Systems Engineer but by the organization as a whole to model their requirements. The requirements diagram may model requirements from the business case requirements, which could then drive functional requirements that subsequently could be constrained or extended by non-functional requirements. In the latter case we could be specifying an implementation or tool chain. In Figure 1, we see a typical example of a requirements diagram.
