There are ways to structure your code so that this can be done. Of course, it would require a complete refactor to achieve full test coverage on an existing project, but if you build like this from the beginning, it's feasible.

Is there any literature on this? A test suite that runs in 1s is...kinda crazy sounding on any non-trivial codebase.
