Where is the source-code to define the phase of surefire plugin?

Question

As most of Java developers know, by default the execution phase of maven-surefire-plugin is test, which is of the same value of goal

The default phase for a goal is part of the Mojo annotation that you use when writing maven plugins (which is a good read before embarking in looking at the insides of maven plugins).
