HTTPUNIT
What is HTTPUNIT



HttpUnit is an open source software testing
framework used to perform testing of web sites
without the need for a web browser.
HttpUnit is primarily designed for "black-box"
testing of web sites
HttpUnit is free software available from [HttpUnitSite] that
implements several useful unit testing methods together
with classes for connecting to HTTP servers, processing
HTML, and maintaining stateful sessions.

Recent Version HttpUnit1.7
JavaScript support is very basic at present.
The near-term goal is full JavaScript 1.1
support. Currently, we do not plan to
support browser-specific JavaScript.
HttpUnit supports :
o HTML form submission
o JavaScript
o automatic page redirection and cookies.
o Written in Java, HttpUnit allows Java test
code to process returned pages as text,
XML DOM, or containers of forms, tables
and links



It is well suited to be used in combination
with JUnit.
It easily write tests that verify the proper
behaviour of a web site.
The use of HttpUnit allows for automated
testing of web applications
The center of HttpUnit is the WebConversation
class, which takes the place of a browser talking
to a single site.
 It is responsible for maintaining session context,
which it does via cookies returned by the server.
 To use it, one must create a request and ask the
WebConversation for a response.
For Example:

WebConversation wc = new WebConversation();
WebRequest req = new GetMethodWebRequest(
"http://www.meterware.com/testpage.html" );
WebResponse resp = wc.getResponse( req );


The response may now be manipulated
either as pure text (via the getText()
method), as a DOM (via the getDOM()
method)
WebConversation wc = new WebConversation();
WebResponse resp = wc.getResponse(
"http://www.meterware.com/testpage.html" );
Some Drawbacks to HTTPUnit:
 Tests are tied to page structures.


If you change your page (say, reordering links
or forms), you will break your tests.
Test assertions typically depend on the
content of the page.


If content changes, tests may break.
Checking content is not completely sufficient
for testing Grid portals.
public WebConversation loginToPortal()
throws Exception {
//WebConversation objects are the cornerstone class.
WebConversation wc = new WebConversation();
//We will need to specify the user agent to simulate a browser.
ClientProperties cprops = wc.getClientProperties();
cprops.setUserAgent("Mozilla/5.0");
WebResponse resp = wc.getResponse(portalUrl);
// Find the login form.
// It's not named so we pick it out of an array
String frontPage = resp.getText();
//First make sure we are looking at the right web page.
assertTrue("Failed to get front page",
frontPage.indexOf("Please Login") != -1);
WebForm form = resp.getForms()[1];
assertNotNull("No login form found", form);
// Fill in form and submit
form.setParameter("userName", “admin”);
form.setParameter("password", “admin”);
form.submit();
// Get logged in page
WebResponse resp2 = wc.getCurrentPage();
String page = resp2.getText();
assertFalse("Failed to log in",
page.indexOf("Please Login") != -1);
return wc;
}

types of assertion statements that are used to test your code.
