android automation testing using espresso

Requirements  You need to perform at least 8 tasks to cover the major features of the app, including reading, searching, and downloading articles, jumping to sections, searching for keywords, changing fonts, themes, languages, editing articles (without submission), managing reading lists (generation, deletion, edit names, add articles), general app settings,  The test code must be fully automatic and can be executed for multiple times. Therefore, you should make sure that you go back to the original status at the end of the test execution. For example, if you generated a reading list in your test code, you should delete it at the end; otherwise you cannot generate it again next time you run the test code.  Each task should be elementary, so that it does not contain unnecessary steps. For example, when you want to change the font, you need to open an article (which is a necessary step), but changing general settings is not necessary step. You need to submit the test code as well as a document providing the description and screenshots for each task.
