Not a servlet expert but looking good. Left few suggestions

PerfectSlayer · 2025-08-07T16:03:40Z

❔ question: ‏Are the servlet replaced when using the same path?
What about not extending TomcatRumInjectionForkedTest instead and adding the testRumInjection() to true instead?
TomcatRumInjectionForkedTest could also be renamed TomcatSyncRumInjectionForkedTest for disambiguation.

The servlets are not replaced. They are registered once per tests reason why they are forked. IMHO extending one or another class does not bring a lot of value . In this case I avoided overriding one method
