A repost of my daughter’s article with permission. I added a few notes. This is also included in my “How to in Selenium WebDriver” series.

Testing user login is usually the first testing task for an app. This article will go through typical user login test cases in Selenium WebDriver and highlight a common pitfall in automated testing.

1. One happy 😊 case: Login successfully
2. One alternative 😞 case: Login failed from bad credentials
