Tests Failing because of output field ordering

[jogoncalves]

Hi. Been trying to test my configuration and i think its failing because of the random order in which logstash outputs fields.
Since there's not much documentation on the kind of differences logstash-test-runner detects and how they are displayed on screen, can you explain me what the output below means?

[ 0: { q_param: [ 0: ==> 2 ] } ]

I've checked both the expected output and the resulting output and they are identical, except for the order.
