Some people have open issues about how enabling the profiler in test enviroment. The option ``enable profiler`` working correctly but some people don't want enabling the data collecting in each tests. So you can define in "config_test.yml" the collect parameter to false. The data will collect only in tests that call 
$client->enableProfiler();
