What steps will reproduce the bug?

1. Create an empty latest.js file
2. Run the Node.js test runner

fnm use 20
# Using Node v20.17.0

node --test
# ℹ tests 0
# ℹ suites 0
# ℹ pass 0
# ℹ fail 0
# ℹ cancelled 0
# ℹ skipped 0
# ℹ todo 0
# ℹ duration_ms 4.365042

fnm use 22
# Using Node v22.7.0

node --test
# ✔ latest.js (43.960958ms)
# ℹ tests 1
# ℹ suites 0
# ℹ pass 1
# ℹ fail 0
# ℹ cancelled 0
# ℹ skipped 0
# ℹ todo 0
# ℹ duration_ms 53.687041

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

By default, Node.js will run all files matching these patterns:

**/*.test.?(c|m)js
**/*-test.?(c|m)js
**/*_test.?(c|m)js
**/test-*.?(c|m)js
**/test.?(c|m)js
**/test/**/*.?(c|m)js

What do you see instead?

latest.js filename does not match the above patterns, but is included in node --test

Hey @hyunbinseo , I believe this issue is caused by the following regex matching pattern: https://github.com/nodejs/node/blob/main/lib/internal/test_runner/utils.js#L54 -> *[.-_]test

I've created a repro and proposed a possible solution in this pull request: #54728.
