Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest version (v1.12.0)
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

There is fun confirmVerified(vararg mocks: Any), but it might be handy to just have a shorthand to verify that all invocations of all mocks/spies are verified. Suggested signature: fun confirmAllVerified(): Unit.

Current Behavior

There is no function that allows to confirm that all mock/spy calls were verified.

This looks really like a duplicate of #334.

It might be, although the approach seems a little different. I'll leave it up to you to close this issue if you think this is not the way to go, e.g. if the other issue would be a better approach.
