 The agent and the observation builder as well as an observation wrapper can be passed to the test function like this
 
 ```
-    test_score, test_dones, test_time = run_test(current_parameters, agent, observation_builder=your_observation_builder,

 In order to speed up the test time you can limit the number of trials per test (`nr_trials_per_test=10`). After you have made these changes to the file you can run `python score_tests.py` which will produce an output similiar to this:
