However, due to the limitation of research and development time, software test automation needs to choose a suitable method and a suitable testing tool in order to achieve sufficient testing efficiency. In an FPGA-based software-hardware collaborative application, this paper compares Rational Visual Test and QuickTest Professional in terms of resource occupation and running speed, and concludes that the former has better speed and usability.
software test automation is an execution process of a program, the purpose of software test automation is to find and correct the errors in the tested software as much as possible, and improve the reliability of the software. It is a very important and very complicated work in the software life cycle. In the current situation, what is extremely important to software reliability assurance is still software testing. But how to conduct testing, how to improve the quality and efficiency of testing, so as to ensure the quality and reliability of software products, are still deeply perplexing issues. This article briefly introduces the basic process of software test automation, as well as some commonly used technical means, testing strategies and guidelines, and introduces Visual Test, an automated software testing tool used in work by RaTIonal (now acquired by IBM).
Using this automated testing tool can save a lot of trouble of manual operation, and accurately obtain test data and results. Through the introduction of this article, it is hoped that while more and more people realize the importance of software testing, they can further understand how to correctly select and effectively use various testing methods, technologies and automated testing tools to improve software testing. quality and reliability.
The basic process of software testing Software testing is an extremely complex process. A standardized software testing process usually includes the following basic testing activities: ① Drafting a software testing plan; ② Compiling a software testing outline; ③ Designing and generating test cases; ④ Implementing testing; ⑤ Generating software problem reports.
In fact, the software testing process is basically parallel to the entire software development process. The test plan should be formulated as early as the requirement analysis stage, and other related work, including the formulation of the test outline, the generation of test data, the selection and development of test tools, etc. should also be carried out before the test stage. Sufficient preparation can effectively overcome the blindness of the test, shorten the test cycle, improve the test efficiency, and play the role of mutual inspection between test documents and development documents. In addition, in each test cycle of software testing, test engineers will conduct a complete test on the software under test according to the pre-programmed test outline and prepared test cases. Testing and debugging are usually repeated and alternated.

The purpose of software testing is to find and correct various potential faults and defects in the software with as little time and manpower as possible, and to develop high-quality applications at a faster speed and at a lower cost, which makes testing People's jobs are harder than ever. In many projects, all tasks of testers are mostly handled manually, but in fact, a large part of repetitive testing work can be separated and automatically implemented. There is not enough cooperation between the test team and other teams in large projects to facilitate communication with each other. The implementation of test automation can improve the efficiency of test work. The purpose of using tools is to reduce some manual tests and devote more human resources to more valuable work.
Some software testing tools popular with software developers provide strong support for software testing. This article will introduce the famous package software RaTIonal Visual Test of American RaTIonal Company (now acquired by IBM). One of its important features is that it can automatically drive the running of the program under test. And it can automatically record and replay the program execution process, thus realizing the automation of "review" of the test. Because testing is a process that needs to be repeated, it often needs to be repeated dozens or even hundreds of times. Therefore, this feature greatly improves the automation of software "Re-Test" (Re-Test) and "Regression Test" (Regression), freeing testers from complicated and repetitive manual testing, thus significantly improving Improve software testing efficiency. In addition to the most basic automatic recording and playback function, it also provides a series of auxiliary support functions, such as the recorded program execution process can be automatically converted into a high-level language program with good readability, so that this test driver can The testers make necessary modifications according to the test needs, or even compile it completely by hand. Automatically record and analyze the execution results of comparison tests.
With the increasing complexity of software and hardware collaborative applications, the software must pass comprehensive testing to ensure quality and reliability.
