JUnit jump-start
Never in the field of software
development was so much owed by
so many to so few lines of code.

Running tests

All code is tested.
During development, the first thing we do is run our own programmer's “accep-
tance test.” We code, compile, and run. When we run, we test. The
test
may just be
clicking a button to see if it brings up the expected menu. Nevertheless, every day,
we code, we compile, we run, and
we test
.
When we test, we often find issues—especially on the first run. Therefore, we
code, compile, run, and test again.
Most of us quickly develop a pattern for our informal tests: we add a record,
view a record, edit a record, and delete a record. Running a little test suite like this
by hand is easy enough to do, so we do it—
over and over again
.
