Problem With Struts 2.3.1 and Testing Struts Portlet
----------------------------------------------------
Key: WW-3733
URL: https://issues.apache.org/jira/browse/WW-3733
Project: Struts 2
Issue Type: Bug
Components: Plugin - Portlet
Affects Versions: 2.3.1
Reporter: Bruce Phillips
Priority: Minor
I'm upgrading a Struts 2 portlet application from 2.2.3.1 to 2.3.1. A test of
my Action class that extends StrutsSpringTestCase that passed when using
2.2.3.1 now fails when using version 2.3.1.
I've created a simple Struts 2 portlet example application to demonstrate the
issue. You can download the zipped example here:
http://www.brucephillips.name/struts/struts2helloworldportlet.zip
Unzip the download.
In a terminal window navigate to the project's root folder.
run mvn clean test
The test will pass.
Open the pom.xml and change the struts.version property to 2.3.1 and save your
change
run mvn clean test
The test will now fail.
Here is part of the error message in the test report:
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.314 sec <<<
FAILURE!
testExecute(com.struts2.tutorial.action.DefaultActionTest) Time elapsed: 1.252
sec <<< ERROR!
Error creating bean with name

at
com.opensymphony.xwork2.DefaultActionInvocation.createResult(DefaultActionInvocation.java:224)
I get the same error if the project is using the Struts Spring plugin or not.
I think the error is in the Struts unit testing framework as I can still run
the project successfully. For example after updating the struts.version in
pom.xml enter this command in the terminal window:
mvn jetty:run
When you see the message [INFO] Started Jetty Server go to this URL in your web
browser: http://localhost:8080/struts2helloworldportlet/pluto/index.jsp and
you should see the example portlet.
_____________________________________
Could you register an issue ?
Looks like the problem is with PortletContext which it is not defined.
To solve your problem override the method as below in the
DefaultActionTest class:
@Override
protected ActionProxy getActionProxy(String uri) {
ActionProxy actionProxy = super.getActionProxy(uri);
ActionContext.getContext().put(StrutsStatics.STRUTS_PORTLET_CONTEXT,
new MockPortletContext());
return actionProxy;
}
Thanks in advance
