How is task.id deterministic?

Hi I would like to known where or how exactly is task.id is generated, since I rely on it for my snapshot file names. Thanks for your answers.

It's based on the test filepath, project name and the position inside the suite:

aptsb64bs would be a file path plus project name hash

aptsb64bs_0 is the first suite

aptsb64bs_0_0 is the first test inside the first suite

Thank you that's clear, a few thoughts :

• I have test ids starting with - I don't know if it's expected
• Having the 0_0_etc part also available in the task object as a formatted array (like [0, 1, 0]) could be useful for toMatchFileSnapshot() usage (since most of the time snapshots are saved in the current test folder the unique id part isn't really useful)

Having - at the start is fine, it's part of the file+projectName hash
