Problems solved by technology

To develop an easy-to-test real-time embedded software requires three aspects: testability, testability characteristics and testability factors. In the above methods, either only the testability factors and testability metrics can be measured, or only the testability characteristics and The value of testability metrics, or only one type of information can be obtained, which cannot meet the needs of real-time embedded software development
Not only that, but the above method can only measure the testability of the software in a certain test situation. For example, the key dependencies of the test only reflect the testability of the software when the integration test is performed, and the control chart method can only determine the testability of the software when the white box test Testability and PIE technology can only measure the testability of the software when it is randomly tested. When the test situation of the software changes, these methods are no longer applicable

Embodiment

[0085] The testability of the software of two display control management systems (DCMS) and two mission computer systems (MCS) was measured by using the method provided by the invention. DCMS and MCS are two important subsystems of the avionics system. Among them, DCMS is responsible for receiving and displaying data from other subsystems, and controlling other subsystems according to pilot instructions; MCS calculates aircraft attitude based on sensor data, and performs functions such as flight management and fire control calculation. Most of the functions of the four systems are implemented by embedded software, which are respectively recorded as DCMS α 、DCMS β 、MCS α and MCS β , where version β is an upgraded version of version α. DCMS is detailed belowα The testability measurement process:

[0086] 1. Test situation analysis;

[0087] According to DCMS α The test requirements to determine the test conditions are shown in Table 6:

Abstract

The invention discloses a framework-based real-time embedded software testability measuring method, and belongs to the technical field of real-time embedded software test. The method comprises construction of a real-time embedded software testability measuring framework and real-time embedded software testability measurement, and specifically comprises the following steps of: determining testability factor measurement and testability property measurement of real-time embedded software, and constructing a measurement framework; determining the test condition of the real-time embedded software;selecting testability factor measurement; and finally, finishing measurement calculation. Compared with the prior art, the testability measuring method provided by the invention is performed based onthe framework and different test conditions of the real-time embedded software, and can obtain the testability of the real-time embedded software under different test conditions; a fuzzy comprehensive evaluation mode is adopted for calculation, so the original fuzzy testability property and the testability are quantified and can be compared accurately, and the evaluation result is more comprehensive and accurate.

Description

technical field [0001] The invention belongs to the technical field of real-time embedded software testing, and in particular relates to a framework-based method for measuring the testability of real-time embedded software. Background technique [0002] At present, real-time embedded systems are widely used in aerospace, medical, telecommunications and other fields, and the reliability of the system has become the focus of attention. In real-time embedded systems, the proportion of software functions is increasing day by day, and the quality and reliability of software have become the bottleneck restricting the reliability of the whole system. Therefore, it is necessary to conduct various types of tests on real-time embedded software to ensure software quality. Real-time embedded software is generally closely integrated with hardware and has high real-time requirements, so software testing is difficult and requires a lot of time and cost. Testability is a quality attribute ...
