“make install” really just installs it into nextstep/Emacs.

When you do “make”, the binary is updated (src/emacs -> 
nextstep/Emacs.app/Contents/MacOS/Emacs), which facilitates fast testing.  So, 
only the first “make install” is necessary to test when doing development, 
unless non-preloaded (dumped) lisp files or other resources are changed.  This 
binary gets its resources from what is in nextstep/Emacs.app.

To test run after changes to the C code in src/, I usually do something like

make -j4
../nextstep/Emacs.app/Contents/MacOS/Emacs -q
