Testing View Rendering

[André Faria]

Hello everybody,

In the rails community is very common to test view rendering in the
integration level, and even it the unit level.

In the Java Community, I don't see much concern about that.

I've found something about unit testing velocity views :

Do you guys use to do something like that?

Sometimes my team get bugs in production, because the change the
controller the view does not have test. We would like to be able to
test it without having to write acceptance tests for everything, cause
they are very expensive for us.

Thanks,
Regards,
André Faria

Great post!

So the first thing is you can compile all your templates as part of a
CI build as they are statically typed (for ssp, jade, scaml); so you
can catch templates breaking due to model/controller/API change -
which tends to be the most common cause of stuff breaking
http://scalate.fusesource.org/documentation/user-guide.html#precompiling_templates

In terms of integration testing; you may want to do that inside your
container (e.g. web connector/container + MVC layer or framework of
your choice + scalate).

We have a little integration test framework we tend to use to test
using scalate inside Jetty...
https://github.com/scalate/scalate/blob/master/samples/scalate-sample/src/test/scala/org/fusesource/scalate/sample/SampleTest.scala

scaladoc here:
http://scalate.fusesource.org/maven/1.5.2/scalate-test/scaladocs/index.html

e.g. here's the assertions...

Or you could try things like Selenium/WebDriver for something a little
more webbyish (which can test different web browsers too)
