How this pull request can be tested ?

Quick and (very) dirty way to test it: rewrite the execute() sub from connector.pm to

sub execute {
    my ($self, %options) = @_;
    return JSON->new->utf8->decode('{"identity":"client-123456789","data":{"domain-987654":{"name":"XXXX","cluster_domcompmgr":{"latencyAvgRead":4873,"throughputRead":641991025,"iopsRead":16599,"iopsWrite":8232,"congestion":0,"oio":150.5,"latencyAvgWrite":287,"throughputWrite":159102785.5}}},"short_message":"OK","extra_message":"","vmware_connector_version":"3.2.5","code":0}');
}
