One bug-raised issuesIf there is a bug in the development process: "Constantly switching the language of the phone to display the phenomenon of flower screen." How do we verify this problem? I think the best way should be automated testing.So what are the tasks that automated testing can accomplish?Simply put, those repetitive testing work can be done by automating:1, set the language of the phone2.
