td.reset(thingsBlewUpSoPleaseLogWarnings=true)

Proposal: a new top-level method designed to be run in an afterEach block of the user's tests, and passed a boolean as to whether or not the test failed.

When td.reset(true) is called, td.js will log a warning to the console that contains a summary of the state of all the test doubles known to it since the last reset, including what they were all invoked with.

Like #161, this would be organized stubbying-by-stubbing ("this stubbing was never satisfied (red flag!)", and "this stubbing was satisfied by these three calls: [list]"`

Not all tests allow for this, but many do. And for those that don't, the user could set the var themselves to manually introspect like so: afterEach(() => td.whatWentWrong(process.env.UGH))

I think this could be a solution to all the issues where people want to sprinkle in td.verify() calls for better messages alone like #148 & #138

Start by reviewing the proposed td.reset(true) and td.whatWentWrong entry points, then read the related issues #161, #148, and #138 for context. Done should include a warning summarizing known test doubles and their calls after a failed test, with unsatisfied stubbings distinguished from satisfied ones.
