PyTest interview questions — Medium

252 medium-level PyTest questions from our Automation Testing bank, each with the correct answer and an explanation of why it is correct.

What this covers

PyTest appears throughout Automation Testing interviews. At medium level, interviewers are typically checking that you have used it in practice: what you configured, what broke, and how you knew it worked. Work through these, then explain your answer out loud; the second part is what interviews actually test.
