Hi

From my point of view, Testing means make sure the application is work as it is expeted or not. Quality means make sure application code is followed the best practices to code or to log the error information or not.

Testing involves operation of a system or application under controlled conditions and evaluating the results. It is oriented to 'detection'. Software QA involves the entire software development PROCESS - monitoring and improving the process, making sure that any agreed-upon standards and procedures are followed, and ensuring that problems are found and dealt with. It is oriented to 'prevention'.
