描述

Issue Description

Bug report

Describe what happened (or what feature you want)

The test com.alibaba.csp.sentinel.adapter.reactor.MonoSentinelOperatorIntegrationTest.testEmitSingleLongTimeRt fails when run by itself. But it passes when other methods run before it. Thus, the test is flaky Acc. to the definitions mentioned in IDOFT.

Describe what you expected to happen

The test should pass when run on its own.

How to reproduce it (as minimally and precisely as possible)

Run the test on its own. It will fail. Run the test class. It will pass.

研究方向
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.
