We think of selenium tests as about useful addition to Unit tests -
and
therefore we use different approach - the person who writes a part of
the applications should prepare tests for this part. And that's
why we
treat selenium tests as a part of the application and store them in
the
application's folder.
Yes, that is different from my use / intention. I try to keep my UI
components very simple. So simple that they don't need tests.
Obviously, using D2W, you have very different concerns and very
different test needs. I have never worked on automated testing for a
D2W app, I can see that would be quite a challenge.
I don't really think that there is any difference between testing D2W
or non-D2W apps since we focus on testing user scenarios and not
components. One can easily break non-D2W app by renaming an attribute
of an entity and you really want an easy way to check for broken
bindings even if all of your unit tests are ok. Also, it is you as a
developer (not QA team) who needs to check the scenarios right after
refactoring and before commiting.
Another thing is that tests maintainence leads to additional work so
we try to write as few tests as possible and check only things that
tend to break or are mission-critical. In our practice this helps
discovering 90% bugs with 10% effort. Remaining 10% are normally
discovered via log4j email error alerts or customer bug reports. And
since these 10% bugs are not mission-critical our customers are still
happy and we don't have to spend much time mainaining tests.
