[fix] Express unable to update past 6.x

[wesleytodd]

Describe the bug

Node.js version: all versions

OS version: Linux, osx and windwos

Description:

The express project has been unable to update to latest supertest for a while now. I don't believe anyone has had a chance to look into the cause of the failures (I know I have not, but will link this issue to the rest of the team after I open it), but the test start failing in ways that look like concurrency in the tests is the problem. In all cases if I run one test at a time it behaves correctly.

Here is the test runs from today, hopefully you can see this before the GHA history is gone:

https://github.com/expressjs/express/pull/6112 https://github.com/expressjs/express/actions/runs/13312249710

Sorry I cannot be more help at the moment, but since it came up again just now I wanted to at least file the issue in case others could spend more time looking into it.

• [x] I have searched through GitHub issues for similar issues.
• [x] I have completely read through the README and documentation.
• [x] I have tested my code with the latest version of Node.js and this package and confirmed it is still not working.
