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).

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 technique for storage-efficient cyber incident reasoning by graph matching. The method begins with a graph pattern that comprises a set of elements with constraints and connections among them. A graph of constraint relations (GoC) in the graph pattern is derived. An activity graph representing activity data captured in association with a host machine is then obtained. In response to a query, one or more subgraphs of the activity graph that satisfy the graph pattern are then located and, in particular, by iteratively solving constraints in the graph pattern. In particular, a single element constraint is solved to generate a result, and that result is propagated to connected constraints in the graph of constraint relations. This process continues until all single element constraints have been evaluated, and all propagations have been performed. The subgraphs of the activity graph that result are then returned in response to a database query.

An Activity Diagram is partitioned into appropriately-sized panels. The panels are arranged in the time order of the activities in them. Unused swim lanes are eliminated from each panel, and thus each panel is compressed without adversely affecting legibility. Each swim lane is labeled on each panel. Conditional elements are repeated (and flagged when repeated) if necessary to represent their second path on one or more later panels in the sequence. The panels are displayed to a reader in any of a number of possible media (e.g., electronic, printed, etc.). The system and method solve the large diagram problem by simultaneously allowing for readability and navigability.
