You are testing a highly dynamic UI where automated locators break too often.
You want real feedback on usability, accessibility, and visual accuracy.
You are working with incomplete or frequently changing requirements.
You need exploratory testing to uncover hidden issues beyond the “happy path.”
You are localizing your app and need human eyes to catch cultural or language errors.
You are releasing a hotfix or patch where automation coverage is missing.
You want to avoid automation overhead for short-lived or low-risk features.
