[infinispan-issues] [JBoss JIRA] (ISPN-10855) MultipleCacheManagersTest factory issues are ignored

MultipleCacheManagersTest factory issues are ignored ---------------------------------------------------- Key: ISPN-10855 URL: https://issues.jboss.org/browse/ISPN-10855 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Affects Versions: 9.4.16.Final, 10.0.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 10.1.0.Beta1 TestNG doesn't like exceptions being thrown from {{@Factory}} methods, so when {{MultipleCacheManager.defaultFactory()}} finds a problem with the concrete {{factory()}} implementation or with the annotations it replaces the test instance with a {{TestFrameworkFailure}}. Turns out that doesn't actually work: TestNG ignores the {{TestFrameworkFailure}} instance and runs the tests on a "default instance" of the test class. This is ok when the problem is the concrete class didn't override {{factory()}} and very likely the test author wanted a single test instance, but it's not ok for other errors like {{factory()}} being copy-pasted from super with the wrong class name. We can make TestNG report our factory failures if we implement {{IInstanceInfo}} and mock all the test/configuration methods to throw our exception. We just need to make all configuration methods non-final so we can mock them.
