Facebook Lite App Login Screen Design Android Studio

A login screen is a web page or an entry page to a web/mobile application that requires user identification and authentication, regularly performed by entering a username and password combination. The login process is the most essential feature for any system/application as it provides access to an entire web-site/application or part of it. So, testing of the login screen needs complete coverage.
