Fix the Problem

The steps to take to fix the problem depends on the IDE tool used, environment where the project like standalone, Jenkins CI etc. As the error indicates, you have not specified a valid maven goal or life-cycle phase when running the build. For running tests most common goals are : verify , integration-test or clean verify etc.

You need to look at the documentation of the maven plugin that you are using in the project to know the valid goals to run with maven build tool.
