[appengine-java] Re: How to best run GWTTestCase tests that involve persistence?
I have a pretty good solution for you, Christian, and anyone else trying to
do this, ie GwtTestCase plus GAE test fixtures.
First, create a myapptest.gwt.xml module file.
module rename-to='myapptest'
!-- Inherit base app. --
inherits name='com.mycompany.myapp.myapp'/
!-- Specify the paths for translatable code--
source path='client'/
source path='shared'/
!-- For each service you have, point to a test service class. --
servlet path='/account' class=
'com.mycompany.myapp.server.AccountServiceTestImpl'/
/module
The key here is that you're pointing services to a new class. Thankfully,
the class is a simple subclass of the original service implementation that
adds AppEngine test fixture initialization in the init() method.
public class AccountServiceTestImpl extends AccountServiceImpl {
private final LocalServiceTestHelper helper = new LocalServiceTestHelper(
new LocalDatastoreServiceTestConfig(), newLocalUserServiceTestConfig())
.setEnvIsLoggedIn(true)
.setEnvAuthDomain(test.com)
.setEnvEmail(t...@test.com);
@Override
public void init() throws ServletException {
super.init();
helper.setUp();
}
}
All these files sit in subdirectories of /test so you're not introducing
fixture dependencies in your /src code.

[appengine-java] Re: How to best run GWTTestCase tests that involve persistence?
Hi, I already have two types of tests. One type of test that separately tests the server side logic and the client side logic separately and independently and the second type of test that verifies the integration of both sides. I am also already using SyncProxy for some tests. The reason why I would like to have integration tests using GWTTestCase is that I would like to have them automatically execute from a continuous integration server. I want to verify with those tests that any additional layer of infrastructure like Hibernate or DataNucleus does not introduce any incompatibilities in my data objects. As Hibernate or DataNucleus enhance the objects at runtime it is important for me to verify that these enhanced objects are still compatible when transferring them over the network to the client. A QuestionDefinition object that I create via the Java new operator may not be the same object that exists at runtime after being enhanced (byte code manipulation) by Hibernate or DataNucleus. Do you have any suggestions for that use case for me? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi,
1. I think the proper way is separating the test from
QuestionServiceImpl.
2. For testing QuestionServiceImpl, you should run two separate parts:
server side and client side.
a) In your case, there are no special in the server side.
b) In the client side, you can use GWTTestcase. Your test logic is on
the client side.
However, testing with GWTTestcase are slow. SyncProxy can be used on
the client side to invoke your remote service.
See http://www.gdevelop.com/w/blog/2010/01/10/testing-gwt-rpc-services/
and
http://www.gdevelop.com/w/blog/2010/03/13/invoke-gwt-rpc-services-deployed-on-google-app-engine/
for how to use SyncProxy.

Hello,
I am doing experiments with a simple service QuestionService and I
have a GWTTestCase that calls the QuestionService. All works fine, but
my problem is that in the QuestionServiceImpl constructor I have to
use the LocalServiceTestHelper helper infrastructure in order to make
the whole test case work.
My problem is now that I have to introduce dependencies in my
QuestionServiceImpl on the appengine-testing jar in order to make my
GWTTestCase work! My initial tries were to use the
LocalServiceTestHelper directly in the gwtSetUp and gwtTearDown
methods of the GWTTestCase but that does of course not work, because
those classes are not compatible with the GWT (they obviously cannot
and should not be compiled to java script).
Is there any good way around this that I have to introduce a
dependency on the appengine-testing infrastructure in my service
implementation? Can I somehow detect that I am running in a
GWTTestCase, then I could at least create a if-then-else block that
only instantiates the helper in test mode.
Many thanks for any recommendations!
