I think that Fabian is making a very important point here: All
automated tests are not unit tests. Unit tests are intended to test
the smallest possible unit of code in isolation (or as close to
isolation as can reasonable be achieved). There is an interesting /
provocative article in this topic here: http://www.javaranch.com/
journal/200603/Journal200603.jsp#a1
"They fell into the popular trap of thinking that because they run
the tests with JUnit, they must be unit tests."
"Unit Test: The smallest amount of testable code. Often a single
method/function, sans the use of other methods or classes. Fast!
Thousands of unit tests can run in ten seconds or less! A unit test
NEVER uses:
a database
an app server (or server of any kind)
file/network I/O or file system;
another application;
the console (System.out, System.err, etc.)
logging
most other classes (exceptions include DTO's, String, Integer, mocks
and maybe a few others)."
I find his definition of Unit Test a little restrictive for
WebObjects. My "unit tests" often involve EOF. In any case, it is
worth reading and thinking about.
What I strive for are very simple UI (WOComponent) sub-classes so
that the UI does not need unit testing. For example, to implement an
action method to perform a search I would use a method like this on
my component / page:
public NSArray searchResults() {
return Customer.customersNamed(editingContext(), searchString);
}
Customer.customersNamed() _does_ get test. But searchResults() is so
simple that it could not possibly break (IMHO) and hence does not
need or benefit from testing.
Of course, there could still be a bug if the search criteria in the
UI is not bound to searchString. But that falls under the heading of
functional test (in my mind) and, as Fabian, points out there are
better tools for that sort of testing.
