Once i changed this to `Mockito.verify(adapter, times(numberOfInvocations))` im unable to verify the first param request, as it hits this last `eq(ImmutableMap.of("pageToken", "10", "pageSize", "10"))`. When i changed to the following was able to get the test to pass ``` Mockito.verify(adapter, times(numberOfInvocations)) .execute( eq(HTTPMethod.GET), eq("v1/namespaces"), eq(ImmutableMap.of("pageToken", "10", "pageSize", "10")), any(), eq(ListNamespacesResponse.class), any(), any()); ``` Ive also tried called mockito.verify in two seperate calls similar to what we do in a test like `testCatalogTokenRefresh` but was not able to get this to work for similar reasons, either due to `TooManyActualInvocations` or due to arguments not expected ``` Argument(s) are different! Wanted: rESTCatalogAdapter.execute( GET, "v1/namespaces", {"pageToken" = "", "pageSize" = "10"}, <any>, class org.apache.iceberg.rest.responses.ListNamespacesResponse, <any>, <any> ); ``` -- This is an automated message from the Apache Git Service.
