A process modeling tool for graphically representing a process which includes transactions and events, and for generating computer code representing the process. A graphical tool creates a graphical representation of the transactions and events with graphical symbols, where one or more of such transactions and events may be of an asynchronous nature. A code generator generates computer code in response to information contained in the graphical representation. The computer code is executable on a computer system to cause the computer system to perform one or more operations which emulate the process shown in the graphical representation.

A method for facilitating the management of a test process is proposed. For this purpose, the different test scenarios included in the process and their execution dependencies are represented by means of a customized UML activity diagram (300a). An execution weight is also associated with each test scenario (for example, defined by the man-hours required for its execution). In this way, it is possible to identify critical test scenarios (315g), which may impair the execution of the whole test process when they fail (because many other test scenarios depend on their successful completion). The order of execution of the test scenarios is then arranged into a test plan, so as to minimize the time required to reach the critical test scenarios. Preferably, the same process is repeated whenever any runtime condition changes (such when a test scenario fails).

A method for model-based testing of an industrial system includes modeling functionality of an industrial system using a modeling computer language, enhancing the model by adding functionality or refining existing functionality, generating test suites from the system model, and executing the test suites. The modeling computer language is the Unified Modeling Language (UML), wherein modeling includes defining UML use case diagrams to describe relationships among use cases specified for the system and actors who interact with the system according to the use cases, defining UML activity diagrams to model process logic of each use case, wherein the activity diagrams comprise a sequence of activities and transitions, and defining UML class diagrams to specify data categories and attributes that are inputs to the activities of the activity diagrams, wherein data categories relevant for a use case are modeled as test variables in the activity diagram.

An automated approach to generating test cases for performance testing may be used for test case planning, early in the software development process, when a UML use case model and its activity diagram refinement are specified. The planned performance tests are executed later in the software development process, after the system is developed. The use case model is annotated with operation arrival rates and departure rates. Deterministic state testing (DST) generation and execution are applied for performance test generation and execution. In addition, a technique is described to generate the most likely test scenarios, labeling each arch in the activity diagram with transition probabilities and applying a breadth first search algorithm to select the most likely paths to be tested for each state generated by the DST algorithm.

A process of automatically translating a high level programming language into a hardware description language (HDL), which can use a three-stage translation mechanism to generate the HDL codes corresponding to the functions described by the high level programming language. The first stage translates source codes coded by the high level programming language into an extended activity diagram (EAD). The second stage translates the EAD into a hardware component graph (HCG). The third stage generates the respective signal connections of HDL components according to all edges of the HCG, and outputs an HDL entity and architecture to a file in a string form, thereby completing the entire translation.
