Description
Description
SnapshotDiffManager spy = spy(snapshotDiffManager);
doAnswer(invocation -> {
String[] split = invocation.getArgument(0, String.class).split("/");
String keyName = split[split.length - 1];
return Integer.parseInt(keyName.substring(3)) % 2 == 0;
}
).when(spy).isKeyInBucket(anyString(), anyMap(), anyString());This code leads to:
M D RV: Return value of SnapshotDiffManager.isKeyInBucket(String, Map, String) ignored, but method has no side effect At TestSnapshotDiffManager.java:[line 689]
In a Mockito.doAnswer(...) chained call it is OK to ignore the return value.
