Test automation is to give full play to the role or value of tools. For example, tools can 100% execute commands and work hard, so automated testing is suitable for mechanical monotonous testing work, such as regression testing, performance load testing, stress testing, compatibility testing, BVT (Version Building Verification Test) and so on.
The script development and execution of test automation is based on test analysis and design. If there are problems in test analysis and design, tools can't solve such problems. Only with better test analysis and design can we have better automated testing, so it is very important for us to understand the relationship between test analysis/design and automated testing.
The development and use of tools and scripts are all done by people, so people are the first and tools are the second. Test automation is also influenced by culture and process, and the success of test automation is not a technical problem. Today, there are no technical obstacles, which often appear in corporate culture, R&D process and development quality (such as standardization and testability of software implementation).
One of the underlying logics of test automation: tools are important, but talents are the decisive factor;
The second underlying logic of test automation: automated testing is based on test analysis and design;
The third underlying logic of test automation: all the test work suitable for automation should be automated as much as possible, and at the same time, an environment conducive to automated testing should be created.
