Bug Report

When running munit (scala) tests I'm getting a lot of warnings like these:

[dd.trace 2025-02-24 16:19:32:097 +0000] [io-compute-0] WARN datadog.trace.instrumentation.junit4.JUnit4Utils - Could not get test method
java.lang.NoSuchMethodException: com.example.Test.Name of test()

	at cats.effect.unsafe.WorkerThread.run(WorkerThread.scala:743)

I guess because munit tests don't correspond to actual methods.
The test result seems visible in datadog.

Expected Behavior

No warnings.

Reproduction Code

package com.example

import munit.CatsEffectSuite

class Test extends CatsEffectSuite {
  test("Name of test") {}
}
