I don't see an obvious hook for when someone is running `port test` to change configure.args (I could, of course, add a post-extract/pre-configure and do some non-declaritive test to see if `port test` is being run and use that to branch - but that feels like a bad design choice).

I think trace mode has a(n elaborate) workaround where it copies binaries and executes the copies, but that doesn't seem like something I should implement in a portfile ;-) [This is another instance where if trace mode were the default, things would 'just work']

The way our cmake PortGroup sets things up, running tests is harder. You 
can configure cmake to allow testing to find the libraries in the build 
tree. See for example what I did in libcbor:

variant tests description {enable tests} {
     depends_test-append         port:cmocka
     configure.args-append       -DWITH_TESTS=ON
     configure.pre_args-replace -DCMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=ON \
-DCMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=OFF            yes         test
