The Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse section of jaxrs-client readme file states

To run the tests in Red Hat JBoss Developer Studio:

You must first set the active Maven profile in project properties to be either arq-managed for running on managed server or arq-remote for running on remote server. Then, to run the tests, right click on the project or individual classes and select Run As --> JUnit Test in the context menu.

This sentence could be probably rewritten to be in a single line, or should use numbered bullets after To run the tests in Red Hat JBoss Developer Studio: part.
