### Question:
AAISingleTransactionClient extends
        GraphInventoryTransactionClient<AAISingleTransactionClient, AAIBaseResourceUri<?, ?>, AAIResourceUri, AAIEdgeLabel> { @Override protected GraphInventoryPatchConverter getPatchConverter() { return this.patchConverter; } protected  AAISingleTransactionClient(AAIResourcesClient resourcesClient, AAIClient aaiClient); @Override void execute(); @Override void execute(boolean dryRun);  }### Answer:
@Test public void confirmPatchFormat() { AAISingleTransactionClient singleTransaction = spy(new AAISingleTransactionClient(aaiClient, client)); GraphInventoryPatchConverter mock = mock(GraphInventoryPatchConverter.class); doReturn(mock).when(singleTransaction).getPatchConverter(); singleTransaction.update(uriA, "{}"); verify(mock, times(1)).convertPatchFormat(any()); }
