* Integration test: WPDO_Comment_Stress_Tester (v2.13.1).
|
||||
*
|
||||
* Verifies the comment stress tester contract:
|
||||
* - State machine: start / get_state / get_progress / cancel
|
||||
* - count_test_comments() matches email-domain marker
|
||||
* - cleanup() removes test comments + cascade
|
||||
* - Input validation throws / errors correctly
|
||||
* - Run benchmark structure
|
||||
*
|
||||
* Note: Realistic mode tests (wp_insert_comment path) use bootstrap stub which
|
||||
* inserts directly without firing filter/action chain.
