try this one:
favcoreApp.mapUrl("^/api/v1/test/([^/]*)$", "json_test")
.setPathInfo("$1");
favcoreApp.mapUrl("^/api/v1/test/test1/(.*)$", "json_test.test1")
.setPathInfo("$1");
favcoreApp.mapUrl("^/api/v1/test/test2/(.*)$", "json_test.test2")
.setPathInfo("$1");
"([^/]*)" match 0 or more characters, which are not '/', so a
url "/api/v1/test/test1/something" won't match any more. This would solve
problems 1 and 2.
The method mapUrl returns a reference to a tnt::Maptarget, which has a
method "setPathInfo". Setting it to "$1" let you access the first bracketed
expression in your component with "request.getPathInfo()", which returns the
passed parameter as a std::string. Without "setPathInfo" you get the full
url.

This is the definition of the constuctor of your component class.
I just saw, that I should add doxygen comments to the classes, so you can find
them in the documentation.
