# Per-test assertion failure counter.
#
# ~keep `run_test` cannot rely on `set -e` to stop a test function at its first
# failed assertion: invoking the function as the condition of an `if` (or either
# side of `&&`/`||`) disables errexit for the whole dynamic extent of that call.
# A failing assertion's `return 1` therefore does not abort the function, and the
# function's exit status ends up being just its *last* command's — so every
# assertion but the last could fail while the test still reported PASS. Each
# assertion helper records its failure here instead, and `run_test` consults the
# counter alongside the exit status. Adding `set -e` would not fix this; errexit
# is already set and is ignored in exactly this context.
