<testsuite name="Testem Tests" tests="78" skipped="0" todo="0" failures="1" timestamp="Mon Apr 01 2024 18:34:10 GMT+0000 (Coordinated Universal Time)" time="12.747">

let fileName = file ? file : className.split('.').slice(-1)[0]

Since the testParser is splitting at . (dot) symbol, resulting name in Github job summary will be 0.Some test but should be Chrome 123.0.Some test or Chrome 123.0 - Some test
