Strictly speaking, all tests pass, however:

Issues found:
(Bug) - UI crashes when deleting a data source used by a resolver before refreshing browser (https://issues.jboss.org/browse/AEROGEAR-7899)

Data source Test button for Postgresql should be disabled before request finishes. It can be clicked repeatedly causing uncontrolled behaviour. Also a loading spinner should be shown for a better UX. https://issues.jboss.org/browse/AEROGEAR-7898
