In general, I agree with you.  But there are exceptions.

There are times when you don't know what your program should be doing
--- for example, what size to make a window border for a pleasant
visual effect, or which options to put on the main menu and which to
relegate to a submenu.

At these times, instant turnaround is a very useful thing to have.
These times seem to occur rather frequently in my development
experience.

There's also the argument that, if I make ten changes and then rerun my
test suite, a failure can be caused by any of the ten changes; while if
I rerun the test suite after each change, the failure can only be
caused by the change I just made.

And there are times when the libraries or platform simply are not doing
what the documentation claims they will do; I run into this constantly
when programming in JavaScript.  Instant feedback makes characterizing
their behavior much more pleasant.

There's the final argument that correcting errors in your understanding
of your program as soon as possible is a very useful thing.  When I'm
programming in environments with a single-stepping debugger, I usually
single-step through every line of my code the first time I run it to
make sure it's doing what I think it's doing.  Read-eval-print loops
are also helpful for this kind of thing.
