An Embarrassing Defect at Medium Due to Lack E2E Automation Regression Testing

Another example of lacking test automation knowledge and failing to do real CI/CD everywhere.

This morning (2024-09-06), I received an email from Medium, surprised by the obvious defect in it.

About two hours later, got another apology email.

The second email content:

Clearly, this is a defect introduced by a software update, and regression testing failed. This is another example of regression testing often neglected, and E2E Automated Regression Testing needs to be included in the CI/CD process (which is rarely done).
