Embedded software testing method based on grey box testing technology

Abstract

The invention provides an embedded software testing method based on a grey box testing technology, which comprises the following steps of: testing software requirements and design documents, and statically examining a software program; determining a software test type and range, and analyzing and extracting software test requirements; the software test requirements are reviewed; designing a software test case by using a grey box test idea; and establishing a test environment and executing the software test case, and recording and storing a test result at the same time. According to the method, the unit test case is designed by using a grey box test idea, and a black box test case design method and a white box test case design method are organically integrated, so that the test case and the test data which can meet the design function and have a relatively high test coverage rate are finally designed; therefore, the tested product has a higher functional safety level.

Description

technical field [0001] The present application relates to the technical field of embedded software testing, in particular, to an embedded software testing method based on gray box testing technology. Background technique [0002] In recent years, the scale and complexity of embedded software have increased dramatically, especially in the fields of national defense, rail transit, automobiles, civil aviation, and industrial control, and users have stricter requirements on the quality of embedded software. tolerance is getting lower and lower. Therefore, how to effectively improve the quality of embedded software has become an urgent problem to be solved. [0003] As we all know, software testing is an important means to ensure high-quality, high-reliability software, especially for embedded software. Commonly used testing techniques for embedded software testing include: black-box testing techniques and white-box testing techniques. Black-box testing is also called function...

Problems solved by technology

Black-box testing is also called functional testing. This type of testing method finds software defects according to the purpose and external characteristics of the software. The biggest advantage of black-box testing is that it does not need to understand the internal structure of the program. It only needs to design corresponding test cases according to the requirements. According to the output As a result, it is judged whether the function of the embedded program is correct; however, the test coverage obtained by the black box test is low, so that it is impossible to strongly guarantee that the tested software has good reliability and security

White-box testing, also known as structural testing, verifies whether the internal logical structure of the program is implemented correctly. Testers must understand the internal structure and processing flow of the software, and find software defects according to the internal structure of the program; white-box testing is closely related to software coverage , can perform coverage test on specific parts inside the program to obtain high test coverage; however, pure use of white box testing will result in the omission of testing of functional requirements and low testing efficiency
