Subject: [PATCH] [IMP] web: qunit: debug doesn't completely finishes the test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added debugTestId url searchParam that executes that test in debug mode.

While in debug mode, one can fully interact with it, and the console logs
the test's internal state.

closes odoo/odoo#92770
