Description
Modified
StreamsDemoTest.javato sort the serialized fields before comparing them with the expected output. This ensures that the test is deterministic and doesn't depend on the iteration order ofClass.getDeclaredFields(), which does not guarantee consistency.Motivation
NonDex detected test flakiness in 2 tests:
net.openhft.chronicle.wire.domestic.streaming.streams.StreamsDemoTest.streamTypeMarketDataSimplenet.openhft.chronicle.wire.domestic.streaming.streams.StreamsDemoTest.streamTypeMarketDataSimpleWIthInvalidThis PR is verified by NonDex to fix them all. The root cause was that the tests asserted a specific order of fields in the serialized YAML string. Since `SelfDescribingMarshallable` uses reflection to discover fields, the order is not guaranteed. An example of NonDex output with detected test failures is attached.
