Description

org.apache.struts2.StrutsJUnit4TestCase is not pushing the ACTION_MAPPING into the context which results in the following NPE when testing a Struts action and using the struts-rest plugin.

 java.lang.NullPointerException
	at org.apache.struts2.rest.RestWorkflowInterceptor.doIntercept(RestWorkflowInterceptor.java:205)

The issue can be replicated with this sample github project

https://github.com/zepernick/struts25-rest-junit

The current work around is to override the org.apache.struts2.StrutsJUnit4TestCase#getActionProxy and add

        ActionMapping mapping = getActionMapping(request);
        ServletActionContext.getContext().put(ServletActionContext.ACTION_MAPPING, mapping);
