# X_TEST_BUDGET_INVALID

## Means

a test memory budget or worker cap env var does not parse

## Typical cause

ULTIMATE_TEST_MEMORY_BUDGET is not a size like 3g/512m, or ULTIMATE_TEST_MAX_WORKERS is not a positive integer

## Fix

ULTIMATE_TEST_MEMORY_BUDGET=3g x verify   # or unset it; ULTIMATE_TEST_MAX_WORKERS takes a positive integer
