Repository: apache/incubator-seata (2025-06-27T14:30:50Z)

Issue:
TransactionScopeTest cannot run normally and throws an exception
### Check Ahead

- [x] I have searched the [issues](https://github.com/seata/seata/issues) of this repository and believe that this is not a duplicate.


### Ⅰ. Issue Description

When running the test `TransactionScopeTest`, I found that the original test could not run properly and assertion errors would occur.

A more detailed location is in `testGlobalTransactional()`. When running this method, an assertion error occurs.

### Ⅱ. Describe what happened

Stack Trace:

### Ⅲ. Describe what you expected to happen

_No response_

### Ⅳ. How to reproduce it (as minimally and precisely as possible)

_No response_

### Ⅴ. Anything else we need to know?

_No response_

### Ⅵ. Environment

JDK17
Module: spring.kt
Test class: TransactionScopeTest


Discussion:
Does this test fail every time, or is it a flaky test that only fails occasionally?
> 这个测试每次都会失败吗？还是说它是一个不稳定的测试，只是偶尔失败？

I remember I tested it four or five times in a row, and it failed every time (but considering it was merged code, maybe it was a problem with my environment?)
> I remember I tested it four or five times in a row, and it failed every time (but considering it was merged code, maybe it was a problem with my environment?)

If the issue occurred in GitHub Actions, it’s probably not related to your local environment.
Would you mind checking whether the same issue occurred in any of the recent runs?

If it turns out to be consistent, contributing a fix through a PR could be a good idea!

First, I roughly checked the workflow configuration of Github Action, which enabled tests for all modules (except the excluded modules server and console), so there is no possibility that Kotlin tests are excluded. Second, I checked the logs of recent actions and found that there is no record of TransactionScopeTest (Spring module)!!! However, other tests of Spring module can be found, which may need to be paid attention to (this target test may not be executed at all!)... @YongGoose @funky-eyes 
I think this issue needs to be taken seriously.😣
