✅(jest) Better scoping of tests execution

[dubzzz]

Description

Tests used to be scoped via their configuration file. Starting at this PR, they will be scoped via dedicated directories.

It would avoid having Jest to scan all files of the directory including some not relevant for the test itself. With new scoping the directory being passed will be only for this test, not for others. As such Jest can scan all of it.
