This article mainly explains "what are the main work of software test engineers". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "what are the main work of software test engineers?"

Find defects in the software through testing

This is the main goal of software test execution. Software defects include not only whether the function of the software is perfect, but also whether the user experience of the software is friendly, whether the bearing capacity of the software is complete, and whether the use path of the software is smooth. Testing technology is mainly divided into two categories: black-box testing and white-box testing. Among them, the black box testing techniques mainly include equivalent class division method, boundary value method, causality diagram method, state diagram method, test outline method and all kinds of typical software fault models, etc. the main techniques of white box testing are statement coverage, branch coverage, decision coverage, basic path coverage and so on.

Software testing runs through the life cycle of the product.

Software testing needs to participate in the whole process from requirements to the whole product launch. The complete software testing work includes unit testing, integration testing, validation testing and system testing. Unit testing is mainly completed in the coding phase, which is done jointly by developers and software test engineers, and is mainly based on detailed testing. Confirmation testing and system testing is to verify the consistency of the functions and requirements of the software and whether the system functions of the software meet the needs of users under the corresponding hardware conditions after the completion of software development, which is mainly based on the needs of users.

Preparation and submission of test report

When the software testing is completed, the defects found need to be written into a formal test report and submitted to the developer for defect identification and repair. The most important requirement for writing test reports is to avoid the recurrence of defects.

Overall analysis of software quality

After all the tests are completed, testers need to analyze the software quality according to the test results, including defect rate, defect distribution, defect repair trend and so on. The specific metrics of various quality characteristics of the software, including functionality, reliability, ease of use, security, time and resource characteristics, are given. Finally, a conclusion is given as to whether the software can be released or submitted to users.

At this point, I believe you have a deeper understanding of "what is the main work of software test engineers?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
