© 1999 IEEE. Writing device drivers is one of the most difficult tasks to develop or port operating systems (OSs). A device driver needs to be described according to the target device and OS. In the description, programmers must know information about hardware such as specifications of devices and carefully describe complex parts such as timing control. This paper proposes a support system for device driver generation. The inputs for the system are device driver specification which shows operations of the device, OS dependent specification which shows dependent parts on the OS, and device dependent specification which shows dependent parts on the device. As an example, network devices are adopted. The inputs to generate device drivers by the proposed system are described.

© 1999 IEEE. Test-cases play an important roll for high quality software testing. Inadequate test-cases may cause bugs remaining after testing. Overlapped test-cases lead to increases in testing costs. The paper proposes a test-case generation method with the EIAG (Event InterActions Graph) and the ISTC (Interaction Sequences Testing Criteria). The EIAG represents behavior of concurrent programs. It consists of Event Graphs and Interactions. An Event Graph is a control flow graph of a program unit in a concurrent program. The Interactions represent interactions (synchronizations, communications and waits) between the program units. The ISTC proposed are based on sequences of Interactions. The cooperated paths (copaths) on the EIAG as test-cases satisfying the ISTC are generated. The generated copaths can detect dead (unreachable) statements which concern interactions, and they can find some communication errors and deadlocks in testing. It is, however, necessary to validate feasibility of the generated copaths.

© 1998 IEEE. Test-cases play an important role for high quality of software testing. Inadequate test-cases may cause bugs remaining after testing. Overlapped ones lead to the increases in testing costs. This paper proposes the Event InterActions Graph (EIAG) representing behavior of concurrent programs including any task-type and the cooperated paths (copaths) on the EIAG as test-cases, and describes the test-case generation tool (TCgen) for concurrent programs written in Ada programming language. The EIAG consists of Event Graphs and Interactions. An Event Graph is a control flow graph of a program unit in a concurrent program. The interactions represent interactions such as synchronizations between the program units. TCgen generates test-cases as copaths from an Ada concurrent program. The generated copaths satisfy given testing criteria. They can find some communication errors in testing and detecting unreachable statements which concern interactions. It is, however, necessary to validate feasibility of the generated copaths.

Test-case generation method for concurrent programs including task-types

A task-type in concurrent programs is a template of task-instances which are dynamically generated in execution of the programs. The number of the generated task-instances may not be statically determined. Therefore, test-cases generated by our previously proposed method may not be realized in execution of the programs. This paper proposes an enhanced test-case generation method. Concurrent programs are classified into four kinds under two viewpoints: whether the number of task-instances generated from a task-type can be determined statically or dynamically, and whether or not the task-instances communicate with each other. The enhanced method uses a modified Event InterActions Graph(EIAG). The EIAG consists of Event Graphs and Interactions. An Event Graph is an abstract control flow graph of a program unit. The Interactions represent interactions between the units. Because the modified EIAG represents more accurate behavior of a program than the EIAG does, test-cases generated by the enhanced method increase the possibility of realizing themselves. The test-cases in the method increase in number. The method, however, is practical in the sense that the number of task-instances generated from a task-type is restricted.

© 1996 IEEE. Software testing generally proceeds as follows: generating test-cases, selecting test-data, executing a test target program, inspecting execution result and evaluating whether testing has already been sufficient or not yet. As for methods for structural testing of programs, the way using a coverage, where the coverage means what extent given testing criteria are satisfied, is noted. At the evaluating step, whether or not we finish the testing is determined in view of the coverage. This paper proposes a method for structural testing of concurrent programs written in Ada programming language, especially, test-case generation and execution of the programs. The Event InterActions Graph (EIAG) is used as a model for concurrent programs. The EIAG consists of Event Graphs and Interactions. An Event Graph is a control flow graph of a program unit in a concurrent program. The Interactions represent interactions between the program units. Program units are such as procedures, functions and task-Types. After generating test-cases on the EIAG, a method for selecting test-data is described and measures to cope with infeasible test-cases with which are generated in this step is clarified. And a forced execution of a test target concurrent program in order to solve the nondeterministic execution is investigated. The nondeterministic execution is characteristic of concurrent programs.

© 1995 IEEE. Test cases play an important role for high-quality software testing. Inadequate test-cases may cause bugs to remain after testing. Overlapped test cases may increase costs. This paper proposes an event interactions graph (EIAG), representing the behavior of concurrent programs and the cooperated paths (copaths) on the EIAG as test cases. The EIAG consists of event graphs and interactions. An event graph is a control flow graph of a program unit in a concurrent program. The interactions are synchronizations, communications and waits between the program units. Copaths can be generated automatically by the algorithms which are presented in this paper. The generated copaths can detect dead (unreachable) statements and can find some communication errors in testing. However, it is necessary to validate the feasibility of the generated copaths.
