What do you think about mutation testing applied to components?

I’d love to hear your thoughts on mutation testing when applied to components. In my experience, it doesn’t seem to make much sense because it often reports that tests still pass after altering aspects that aren’t relevant to the component’s behavior. To me, this type of testing seems more suited for pure unit tests. What’s your perspective on this?

• Make your test fail
• Should I write a test or fix a bug?
