Review Comment:
Tests fail because the order or file names in `filenames` is not ensured.
```suggestion
private void assertFilenamesInStateMap(Collection<String>
expectedFilenames) throws IOException {
StateMap states = runner.getStateManager().getState(Scope.LOCAL);
Set<String> actualFileNames = states.toMap().entrySet().stream()
.filter(entry -> entry.getKey().endsWith("filename"))
.map(Entry::getValue)
.collect(Collectors.toSet());
assertEquals(new HashSet<>(expectedFilenames), actualFileNames);
}
```
