How to run tests while building a port?

[Mojca Miklavec]

Hi,

I know that I can run "[sudo] port test p5.20-foo" to run the tests,
but that usually requires rebuilding the whole port.

I also know that one could add "test.run yes" to the port, but that
requires modifications to the port.

Is there any shortcut to build + test + install at the same time
without modifying the port?

Thank you,
