# X_TEST_PACE_INVALID

## Means

ULTIMATE_TEST_PACE is not a number at or above 1

## Typical cause

the variable the gate sets on each test run it starts was set by hand to a value that does not parse, or to one below 1

## Fix

`env -u ULTIMATE_TEST_PACE bun test <file>` — the gate measures the pace and sets it itself; unset is pace 1
