The advantages of testing automation:

① More convenient for regression testing: conducting regression testing involves testing all functional modules of the system. Long cycle regression testing requires a large workload and frequent testing, making it suitable for testing automation. Due to the well-designed scripts and test cases for testing, the expected results can also be anticipated. Automating regression testing can greatly improve efficiency and shorten regression time.

② Simulate real situations: It is possible to perform tests that cannot be manually tested, such as testing the system's load for thousands of concurrent users, which cannot be achieved by testing personnel. However, using testing automation tools can simulate the concurrent process of multiple users.

③ Effectively utilizing human and material resources: Frequent mechanized actions can be executed through testing automation, reducing the occurrence of errors and better utilizing human resources.

④ Reuse of testing: Due to the use of automated scripting technology in testing automation, it is possible to use the same test cases in different testing processes with minimal or even no modifications.

⑤ Reducing human errors: testing automation is done by machines, and there is no human negligence or error during the execution process. Test design completely determines the quality of testing, which can reduce human errors.
