Constructors Summary
public TestPeopleFinderServlet()
Default constructor.

public TestPeopleFinderServlet(String name)
Constructor with a test name

        super(name);
public TestPeopleFinderServlet(String name, Test t)
Constructor used to wrap another test with a Cactus test.

Methods Summary
public voidbeginValidSearch(org.apache.cactus.WebRequest request)
Invoked on the "client-side" (within the test runner) before running the validSearch test.

        // Add a search parameter
        request.addParameter(PersonDAO.FIRST_NAME, "John");
public voidendNoSearchArguments(org.apache.cactus.WebResponse response)

        // Even with no search arguments, the servlet should return a response
        assertNotNull("No response returned from servlet",
                      response.getText());
        // The response should contain the key phrase "Invalid search",
        // indicating a bad search request.
        assertTrue("Response from servlet does not contain \"Invalid search\": "
                   + response.getText(),
                   response.getText().indexOf("Invalid search") >= 0);
public voidendValidSearch(org.apache.cactus.WebResponse response)
Invoked on the "client-side" (within the test runner) after the validSearch test completes and sends a response to the test runner.

        // The servlet should return some response
        assertNotNull("No response provided by servlet",
                      response.getText());
        // Since this was a valid search, there should be no "Error"
        // text in the response HTML
        assertTrue("Response from servlet contains the \"Error:\" label: "
                   + response.getText(),
                   response.getText().indexOf("Error:") < 0);
        // A valid search result will contain a search results header.
        assertTrue("Response doesn't contain a \"Search Results\" header: "
                   + response.getText(),
                   response.getText().indexOf("Search Results") >= 0);
private voidinvokeGet()
Invoke the GET method on the servlet in our fixture. If any exceptions are generated, fail the test.

        try {
            mPFServlet.doGet(this.request, this.response);
        }
        catch (IOException ioe) {
            fail("Unexpected IO exception: " + ioe.getMessage());
        }
        catch (ServletException se) {
            fail("Unexpected servlet exception: " + se.getMessage());
        }
private voidinvokeGetDispatch()

        try {
            RequestDispatcher dispatcher = 
                config.getServletContext().getRequestDispatcher("/search-servlet");
            dispatcher.forward(request, response);
        }
        catch (IOException ioe) {
            fail("Unexpected IO exception: " + ioe.getMessage());
        }
        catch (ServletException se) {
            fail("Unexpected servlet exception: " + se.getMessage());
        }
protected voidsetUp()
Set up the test fixture. In this case, create the servlet instace

        // Create the servlet instance.  We also initialize the servlet
        // here, so that we know it's only done once.  If any tests
        // require an uninitialized servlet for some reason, then the
        // test will have to create its own servlet instance.
        mPFServlet = new PeopleFinderServlet();
        try {
            mPFServlet.init(this.config);
        }
        catch (ServletException se) {
            fail("Unexpected servlet exception while setting up test case: "
                 + se.getMessage());
        }
protected voidtearDown()
Tear down the test fixture. Invoke the servlet's destroy method, to ensure any servlet cleanup occurs.

        mPFServlet.destroy();
        mPFServlet = null;
public voidtestNoSearchArguments()

        // Invoke the doGet method on the servlet using the request
        // that was generated through the proxy.  This request should
        // include no search arguments, since we have not added any in
        // a begin method
        // Un-comment one of the lines below to either invoke the GET 
        // handler directly (invokeGet()), or with a dispatch
        // (invokeGetDispatch()).
        invokeGetDispatch();
        // invokeGet();
public voidtestPeopleToHTML()
Test the HTML conversion util on PeopleFinderServlet

        // Create a test person, and the equivalent HTML snippet to be
        // expected from the method
        String fname = "Andy";
        String lname = "Long";
        String eAddr = "andy.long@buffaloimports.org";
        Person samplePerson = new Person();
        samplePerson.setFirstName(fname);
        samplePerson.setLastName(lname);
        samplePerson.addEmailAddress(eAddr);
        
        StringBuffer sampleHTML = new StringBuffer();
        sampleHTML.append("<tr bgcolor=\"#EEEEEE\"><td>")
            .append(lname).append("</td><td>").append(fname)
            .append("</td><td>").append(eAddr).append("</td></tr>");
        
        // Now apply the method to our Person and validate the results
        String result = PeopleFinderServlet.personToHTML(samplePerson);
        assertEquals("HMTL generated from sample person is not as expected",
                     result, sampleHTML.toString());
public voidtestValidSearch()
Ensure that a valid response is generated from a valid search

        // Simply invoke the servlet's doGet() method, using
        // the request constructed in the begin method
        invokeGet();
