We have a lot of validators for scenarios, but we do not check input arguments. There are two cases: 1) user forget specify some argument; 2) user specify redundant argument In both cases, we will get "TypeError" for each iteration. This validator is not implemented like others, since it doesn't need constructed clients and it looks like more syntax check. Also, this patch fixes one of our samples: samples/tasks/scenarios/dummy/dummy-random-action.[json/yaml] Change-Id: Id3aad571dfc93f8074c724595440979cfd435e2c
