GWT Tests with Sling

[Thorsten Rössner]

Hello everybody,

I'm in the development team of a new CMS which is based on Sling.
I want to use GWT for the GUI of the backend. For this purpose I adapted
the servlet in the contrib package of the Sling project to work with GWT
1.6.4. This works fine. I use the gwt-maven-plugin for creating the
bundles. In addition I got the hosted mode and debugging working, using
the Sling installation for server side code. Summing up, I can use GWT
for the backend GUI.

Now I want to test my GWT classes. GWT provides the test class
GWTTestCase, that are executed with the help of the gwt-maven-plugin.
The tests are running. The problem is, that I cant test my GWT classes
because they use services for getting data from the server per RPC. Does
anybody now, how to get the tests run in the Sling environment (the OSGi
environment)? I need the OSGi services and the repository for the tests.

Does anybody have an alternative method for testing GWT with Sling?

Thanks for your help.
Best regards
Thorsten

Good choice!, Sling is the most suitable tool to this purpose :).

IMHO, you´re talking about in-container testing. You need a Sling
instance running while the tests are executed. According to this, you
might want to have a look at the Sling integration test module [1].
This module uses the cargo plugin [2] in order to get in-container
testing.

Hope this helps.

BR,

Juanjo.

It seems there are several that are doing this, basing their admin
console on GWT. There might be an opportunity to put together an open
source project here around this, since there would otherwise be a lot
of duplicate effort, and I don't think there's much competitive
advantage in having a proprietary admin console for an open source
cms.

What do you mean by "admin console" ? If you have something like the
Felix Web Console [1] in mind, there is already such a beast, which is
being actively developed.

Otherwise, I would be eager to hear your requirements and to discuss,
whether we could use the Web Console for your requirements or whether
another console is required.

No I was of course thinking about content editors. The "admin console"
is an umbrella term we use internally here to mean those things.

Yes, I´m sure Thorsten is thinking about a content editor instead an
OSGi environment admin console.

Thanks for the clarification.

In this case, I would assume, that the Sling project is probably a good
candidate to be such an open-source project.

Even GWT based content editors? It would drag in a number of
dependencies, not all of them apache licensed.

Well, that of course then amounts to a problem - luckily GWT itself is
ASL2 licensed. And as long as the dependencies have acceptable licenses
(MIT and BSD come to mind) there is not an issue, either. Where it
starts getting problematic is the LGPL and GPL licenses.

I think a GWT content editor is possible without LGPL and GPL
licenses. Currently, I´m working in a GWT GUI involving just only GWT
libraries (ASL2), GWT incubator (ASL2) and google-gin (ASL2). BTW,
google-gin [1] is a dependency injection framework very interesting in
order to design a good testing approach with GWT.

I'm also working on a GWT-Sling integration. I'm still making some tests for
the Sling Explorer (with a minimal amount of dependencies) and I will
publish this week what I'm doing. Now, it is completly based on the ASF
2.0 licence.
Thanks to the "noserver" GWT option & the Sling Fs service, it is possible
to run the gwt application in the hosted mode and have an access to the
Sling resources (services, scripts, static resources, ..). I have not yet
make some unit tests.

I'm also using the maven gwt plugin.
