[Mockobjects-java-users] Beginner questions

[<lau...@ma...>]

Hi,

I'm having a hard time wrapping my head around this MO concept. I think I
need some help. I'm writing a general purpose parameter parser for servlets.
Basically, I want the servlet to validate that all required parameters are
part of the request. So in my parser tests, I want to use a mock object (a
MockHttpServletRequest) to implement the request parameter of my method.
Now, my test looks like this:


/*
 * Test for ParameterParser
 */
package ca.masq.servlet;

import junit.framework.TestCase;
import junit.framework.Test;
import junit.framework.TestSuite;

import javax.servlet.http.HttpServletRequest;

import com.mockobjects.*;
import com.mockobjects.*;
import com.mockobjects.util.TestCaseMo;
import com.mockobjects.servlet.MockHttpServletRequest;

public class ParameterParser_UnitTest extends TestCaseMo {

    ParameterParser parser;
    MockHttpServletRequest servletRequest;

    public ParameterParser_UnitTest(java.lang.String testName) {
        super(testName);
    }

    public static void main(java.lang.String[] args) {
        junit.textui.TestRunner.run(suite());
    }

    public static Test suite() {
        TestSuite suite = new TestSuite(ParameterParser_UnitTest.class);

        return suite;
    }

    public void setUp() {
        servletRequest = new MockHttpServletRequest();
    }

    public void testCreateWithNullRequest() {
        try {
            parser = new ParameterParser(new String[] {"foo"}, null);
            fail("Exception expected");
        } catch (IllegalArgumentException iae) {
            assertTrue(true);
        }
    }

	.
	.
	.

    /*
     * No error occurs here.
     */
    public void testNoMissingParameters() {
        String[] requiredParams = { "param1", "param2", "param3" };
        servletRequest.setupAddParameter("param1", "value1");
        servletRequest.setupAddParameter("param2", "value2");
        servletRequest.setupAddParameter("param3", "value3");
        parser = new ParameterParser(requiredParams, servletRequest);
        assertTrue("Required parameter missing", parser.getMissingParameters() == null);
    }

}

in the testNoMissingParameters() method, I get an error. This kinda tells me
that I'm not setting up the servlet properly. Am I correct in my assessment?
What am I not understanding at this point?

Thanks,

L
