An Automatic Test Method Based on Embedded Script

Abstract

The invention belongs to the technical field of digital system test, and designs an automatic test method based on an embedded script. The efficient automatic test considering the test logic compilingefficiency and the test operation running efficiency is realized. According to the technical scheme, the method comprises the following steps of 1, generating adapter code in a unified way after alltest variables are listed out in a centralized way, so that the variables can be simultaneously operated or observed by script program and tested system program; and 2, embedding the test script program segment in the tested system code so that the test logic and the tested system logic are alternately executed according to the determined sequence; setting, reading or recording the same test variables in a memory reading and writing mode; and completing the test process.

Description

technical field [0001] The invention belongs to the technical field of digital system testing, and in particular relates to an automatic testing method based on mixed programming of a mainstream programming language (such as C++) and a scripting language (such as LUA). Background technique [0002] Digital system functional testing is a process consisting of three operations: system state setting, observation and recording. [0003] If the setting, observation and recording operations can all be performed on a digital computer, then the main task of the system test is to organize these three types of operations according to the timing and conditional relationship to form a test logic that can be used to judge whether the system function meets expectations. System testing is usually done by people (system function block diagram as figure 1 shown). When the test logic can be expressed in a programming language, the entire test process can be performed by the computer, so as ...

Problems solved by technology

[0006] 1. It is necessary to design complex inter-program communication protocols and require a certain quality of communication links;

[0007] 2. Test variables need to be registered in the test program and the program under test at the same time. When the set of test variables changes, the test program and the program under test must be changed synchronously. The synchronization process is complicated and error-prone;

[0008] 3. Because the communication link delay is unavoidable and difficult to control accurately, the synchronization between the test program and the system under test is poor, the execution frequency of the test operation is limited by the accuracy allowed by the communication delay, and the timing of the test operation is difficult to be accurately reproduced , the test operation effect has a certain randomness
