testsRun must be a non-negative integer

Error message

testsRun must be a non-negative integer

What it means

RangeError guard on testsRun in the remaining-alpha-budget calculation: the number of tests already executed in the lineage must be a non-negative integer because it indexes how far through the alpha-spending series the lineage has progressed.

Solutions

1. Pass a non-negative integer count of tests run

Example fix

Pass a non-negative integer for testsRun (0 or greater).
