Direzione di ricerca
Examine the test class com.alibaba.csp.sentinel.adapter.reactor.MonoSentinelOperatorIntegrationTest, specifically the method testEmitSingleLongTimeRt. Investigate why the test only passes when run with other tests, likely due to shared state or test ordering. Look for static fields, mocked objects, or reactor context that may persist between tests. Consider adding @Before or @After methods to reset state, or use @DirtiesContext to ensure a fresh context for this test.
