Yicong-Huang opened a new issue, #4505:
URL: https://github.com/apache/texera/issues/4505
### Task Summary
`TrivialControlSpec`
(`amber/src/test/scala/org/apache/texera/amber/engine/architecture/control/TrivialControlSpec.scala`)
takes ~70s in CI for only 8 simple tests, making it the single slowest spec in
the Scala test step (~22% of total backend test time).
The bottleneck is in `testControl[T]`:
```scala
probe.receiveWhile(5.minutes, 10.seconds) {
case GetActorRef(...) => ...
case NetworkMessage(...) => ... flag += 1
case other => //skip
}
```
`case other` matches every message, so `receiveWhile` never exits via
partial-function mismatch. Once all expected returns are received, the test
sits idle for the full 10s `receiveWhile` idle timeout before the loop returns.
With 8 tests, that's ~80s of pure waiting.
Replacing `receiveWhile` with a manual loop that exits as soon as `flag ==
expectedValues.length` brings the spec from ~71s to ~1s in local runs.
