Wrap arrayrefs in {} in order to get rid of "Using an array as a reference is deprecated" warning
Ignore data / log files created by Solr
Add some indentation
Refactor the API test script so that it will kill Solr independent from whether the test succeeded or failed
Instead of sleeping for 30 seconds, make 30 attempts to connect to Solr and continue as soon as Solr is up
Flatten out a single "if" condition
Make sure Netcat ("nc") is installed because now it's being used by the API test
Rename "$resp_object" to "$actual_response"
Delete volatile values from expected / actual responses in an unified way; fix "not a ARRAYREF" bug
Merge branch 'travis_ci_api_test'
