Testing JSF 1.2 Managed Beans vs. JSF 1.1

[mraible]

I had the following BasePageTestCase class that I've been using to test my JSF 1.1 pages. Unfortunately, after upgrading to JSF 1.2, it no longer works. Here's the stack trace:

Sorta looks like there is not a mock implementation for the JspFactory.  Just poking thru the code,

it looks like it's trying to find a shared EL context.  You might give shale-test a try.

Ok Matt I ran into a similar problem in a testmigration of an old
project to myfaces 1.2.

Following, make sure that you are on a current container version
implementing the newest jsp and servlet apis (in my case tomcat running
on java 5)
then remove all traces to the jsp-api and any el-implementation (however
commons-el has to be still there if you use tomahawk otherwise you will
get an error, tomahawk references commons-el logger somewhere)

if done it should work.

The main problem with the migration is that old installs relied on a
hogde podge of various deps into el implementations and servlet specs,
1.2 is pure jee5 so any older version of the servlet spec or el or jsp
in your runtime classpath is a source of possible problems.

It seems I need jsp-api 2.1 in my classpath or I get the following error:

java.lang.NoClassDefFoundError: javax/el/ELResolver

After I add that in, I get the following error. Adding/removing commons-el doesn't seem to have an effect. My BasePageTestCase is at http://tinyurl.com/yv68y7.

ERROR - DefaultFacesInitializer.initFaces(126) | Error initializing MyFaces: null
java.lang.NullPointerException
        at org.apache.myfaces.webapp.DefaultFacesInitializer.initFaces(DefaultFacesInitializer.java:102)
        at org.apache.myfaces.webapp.StartupServletContextListener.contextInitialized(StartupServletContextListener.java:57)
        at org.appfuse.web.BasePageTestCase.performFacesContextConfig(BasePageTestCase.java:57)

I'd love to develop a BasePageTestCase that's a bit more implementation agnostic, but that seems somewhat difficult to do.

Following, make sure that you are on a current container version
implementing the newest jsp and servlet apis (in my case tomcat running
on java 5)
then remove all traces to the jsp-api and any el-implementation (however
commons-el has to be still there if you use tomahawk otherwise you will
get an error, tomahawk references commons-el logger somewhere)

if done it should work.

The main problem with the migration is that old installs relied on a
hogde podge of various deps into el implementations and servlet specs,
1.2 is pure jee5 so any older version of the servlet spec or el or jsp
in your runtime classpath is a source of possible problems.

Werner - do you have an example of initializing a FacesContext in a JUnit Test?

Thanks,
