Allows for specifying test verbosity via Maven

[ememisya]

ex: mvn -Dverbosity=10 test See: Level of Verbosity at https://maven.apache.org/surefire/maven-surefire-plugin/examples/testng.html

Can you explain the rationale for this property? Do you want more or less test output?

[ememisya]

The default characteristic of the test goal seems to be no output except the results of the tests after they have been performed. I wanted the ability to see the tests as they are being executed and with which certificates and so on, which lead me to testng's verbosity feature. By implementing the property we can still keep the current behaviour until the developer specifies the verbosity parameter between 1-10 depending on the level of information they wish to see during testing.

Understood, thanks. I think this is a beneficial change, though I might want to see it driven by a profile instead of a property. It should default to a reasonable value (0?) such that it's not required to be set on the command line. A profile is one straightforward way to accomplish that.

It doesn't bother me if it remains a property, but it should have a more descriptive name. Like ${testng.verbosity}

My only requirement is that it's not necessary to specify -Dproperty.name=X on the command line to build.
