[Webtest] ifstep

It would not normally be recommended that you try to run all
100 tests as part of the same webtest element. You can have
multiple webtest elements and combine them all at the reporting
level. This helps with test isolation.

If you want to selectively run webtest elements you can place them
inside a target with an "if" or "unless" attribute. Ant normally
doesn't let you set a property twice, so you can't have it true
then later false. You can however have it undefined and later
defined. Alternatively, if you don't mind bending Ant practice
a tiny bit use something like the ant-contrib tasks (or a little
bit of groovy) to alter an Ant property.

The ifstep is useful if you want to selectively run steps within
one webtest. In your scenario you could possibly use a <repeat>
step and have a condition for the ifstep based on #count. I think
there was an issue with webtest variables inside repeats for a while
but I think it is fixed. This would be a possible way to go if you
are planning to change the database within the loop.

You can do your database steps using Ant's sql task or if you want
webtest compatible reporting with sqlunit or you could use Groovy
code as well if you wanted.

Cheers, Paul.
