The center of HttpUnit is the WebConversation The center of HttpUnit is the WebConversation class, which takes the place of a browser class, which takes the place of a browser talking to a single site. talking to a single site.

It is responsible for maintaining session It is responsible for maintaining session context, which it does via cookies returned by context, which it does via cookies returned by the server.the server.

To use it, one must create a request and ask To use it, one must create a request and ask the WebConversation for a response. the WebConversation for a response.

For Example:For Example:

WebConversation wc = WebConversation wc = newnew WebConversation(); WebConversation(); WebRequest req = WebRequest req = newnew GetMethodWebRequest( GetMethodWebRequest( "http://www.meterware.com/testpage.html" ); "http://www.meterware.com/testpage.html" );

WebResponse resp = wc.getResponse( req );WebResponse resp = wc.getResponse( req );

The response may now be The response may now be manipulated either as pure text (via manipulated either as pure text (via the getText() method), as a DOM (via the getText() method), as a DOM (via the getDOM() method)the getDOM() method)

WebConversation wc = WebConversation wc = newnew WebConversation(); WebResponse resp = WebConversation(); WebResponse resp = wc.getResponse( wc.getResponse( "http://www.meterware.com/testpage.html" "http://www.meterware.com/testpage.html" ); );

Some Drawbacks to HTTPUnitSome Drawbacks to HTTPUnit:: Tests are tied to page structures.Tests are tied to page structures.

If you change your page (say, reordering If you change your page (say, reordering links or forms), you will break your tests.links or forms), you will break your tests.

Test assertions typically depend on Test assertions typically depend on the content of the page.the content of the page. If content changes, tests may break.If content changes, tests may break. Checking content is not completely Checking content is not completely
