Information from the servlet context

The servlet context contains information about the servlet container and data from the web.xml file. Let's see how STC identifies itself:

ServletContext ctx = getActionServlet().getServletContext();
System.out.println(ctx.getServerInfo());
System.out.println ("Supports Servlet API " + 
     ctx.getMajorVersion() + "." + 
     ctx.getMinorVersion());
	

The output from this bit of code is:

MockServletEngine/1.9.5
Supports Servlet API 2.3

It's simple to add a parameter to the servlet context. Again, we use a simulator class:  

ServletContextSimulator context = (ServletContextSimulator)ctx;
context.setInitParameter("parm1", "value1");

Among the files you may download, there's a program called MockStrutsTestCaseSimulation that gives several examples on how to modify the simulated objects. 

One-time set up in JUnit

A common "problem" when you're coding test cases for Struts actions is that you need some kind of initializations to be carried out before you can start your testing. JUnit has the setUp method for this purpose, but it's called for every test-method in your test class. This may add some unwanted overhead to your program, and there is a way around the problem. 

Use a JUnit suite method with an inner class construction like this (the class name is MockOneTimeSetup):

public static Test suite() { TestSuite suite = new TestSuite(MockOneTimeSetup.class); TestSetup wrapper = new TestSetup(suite) { public void setUp() { // code your set up here } public void tearDown() { // code your tear down here } }; return wrapper; }

It's important to note, however, that the suite method is static. So if you want to save some data, use static variables and fetch them from the ordinary JUnit setUp method. Here's an example where a list of DVDs are fetched once, saved in static storage, and then--for each textXXX-method--saved in session scope:

private static DVDManager dvds; public void setUp() throws Exception { super.setUp(); getSession().setAttribute("dvds", dvds); } public static Test suite() { TestSuite suite = new TestSuite(MockOneTimeSetup.class); TestSetup wrapper = new TestSetup(suite) { public void setUp() { dvds = new DVDManager(); } public void tearDown() { // nothing } }; return wrapper; } . . .
