Some tests in uPortal 3 that use classes from javax.servlet.* in their runtime environment need to be running within a servlet container.
Package org.jasig.portal.servlet in tests directory contains the following basic classes extending JUnit test functionality:

Test Servlet

This servlet performs HTTP tests using Reflection API and sends reports to the HTTP test runner which is a standalone Java application.
It uses the Spring config file to register HTTP test beans. uPortal 3 registers this servlet and its mappings in the web.xml. 

     <servlet>
        <servlet-name>TestServlet</servlet-name>
        <display-name>Test servlet</display-name>
        <servlet-class>org.jasig.portal.servlet.TestServlet</servlet-class>
        <init-param>
            <param-name>contextFileName</param-name>
            <param-value>test_servlet_beans.xml</param-value>
        </init-param>
     </servlet>
     ...
     <!-- uPortal test services -->
     <servlet-mapping>
        <servlet-name>TestServlet</servlet-name>
        <url-pattern>/TestServlet/*</url-pattern>
     </servlet-mapping>

Where contextFileName is the URI to the beans Spring configuration file.
In the example above test beans are defined in the file test_servlet_beans.xml located in the same package:

<beans default-lazy-init="true">
         
    <bean id="containerTest" class="org.jasig.portal.portlet.container.HttpContainerTestBean" singleton="true">
    </bean>
	
    <bean id="portletUrlTest" class="org.jasig.portal.portlet.url.PortletUrlTest" singleton="true">
    </bean>
	
    <bean id="wsrpContainerTest" class="org.jasig.portal.wsrp.WsrpPortletContainerHttpTestBean" singleton="true">
    </bean>
	
</beans>

HTTP Test Runner

It works as a standalone socket server accepting TCP/IP connections from the test servlet and shows results of tests running by that servlet.
Connects to the test servlet to execute HTTP tests specified by the parameters:

  1. bean - defines the name of the test bean
  2. method - defines the name of the test method to be executed
  3. connect - if true the test servlet will send the report to the HTTP test runner
    The httptestrunner.properties sets the port number of the socket server and the test servlet URL. 
    # The test runner properties
port = 10999
servletUrl = http://localhost:8080/uP3/TestServlet
contextXmlFile = test_servlet_beans.xml

HttpTestCase class

It is an extension of JUnit's TestCase with its own initTest() method to initialize a test bean with ServletConfig, HttpServletRequest and HttpServletResponse. Accepts all assertions supported by JUnit. Subclasses need to be registered within the Spring config file of the test servlet.
