In my lh-vim-lib [1] library plugin I provide two sets of tools
- log functions [2] that can fill the qf window with the log messages automatically -- other logging frameworks fail to automatically link to the line where the log is emitted
- assert functions [3] for doing some design by contract. They permit to fail fast in case of unexpected value detected / dump the current callstack / start the debugger

It also provides a function that decodes displayed callstacks on error [4]

I also use a unit test framework [5] for unit testing functions.
