Problem

Currently, there is no endpoint providing testId, making it difficult to consume internal endpoint:

• /plan/{projectKey}-{buildKey}/test/{testId}/quarantine [POST]

	Please, notice endpoint about is not listed in https://docs.atlassian.com/atlassian-bamboo/REST/6.4.1/

Workaround

It is required to review testId from Bamboo's UI or database.
The following query can be used for this purpose:

SELECT full_key,
       test_case_id as testId,
       test_class_name,
       test_case_name,
       quarantining_username,
       quarantine_date
FROM build b
JOIN test_class tcl ON tcl.plan_id=b.build_id
JOIN test_case tc   ON tc.test_class_id=tcl.test_class_id
WHERE b.full_key like 'PROJ-PLAN%'

⚠️This query was designed for Postgres DB and might needs adjustments for a different DB type.
