HttpUnit - call a javascript functin

807591Feb 4 2008 — edited Jun 2 2008
Hi to all,
I'm an italian student and i have some problem with HttpUnit package.
I must test a web application and i implement this java code to download a pdf file: 
TableCell cell = table.getTableCell(4, 0);

WebLink link = cell.getLinks()[0];

WebResponse resp1 = link.click();
		
WebLink[] links = resp1.getLinks();
for (int i=0; i<links.length; i++){
	if (links.getText().equals("Download document")){



		String strOnClick = links[i].getAttribute("onclick");

		links[i].getScriptableDelegate().doEvent(strOnClick);

		System.out.println(strOnClick);

	}

}





With the print I have *"download('428D8B70-9xxxxxxxxx')"* , so I arrive where I want.

I want to download a pdf file from a link like this:

<a href="#" onclick="download('428D8B70-9xxxxxxxxx')">Download document</a>
The html page isn't wrote by me and i can't change it.

The error is:

com.meterware.httpunit.HttpNotFoundException: Error on HTTP request: 404 Not Found [http://localhost:7777/speed/common/docviewer?id=428D8B70-xxxxxxxxxxxxxxxxxx-xxxxx-xxx-xx-xx1&download=true]

Does http://localhost:7777/speed/common/docviewer exist?

Yes, it exist...
If I go to the web application with my computer I can do all action.

If you have another solution to run a javascript function tell me....

It looks like the JavaScript function IS running. If it was not it would not attempt to retrieve http://localhost:7777/speed/common/docviewer?id=428D8B70-xxxxxxxxxxxxxxxxxx-xxxxx-xxx-xx-xx1&download=true

This raises a question in my mind: how do you unit test JavaScript? Is there a JSUnit?

I have change my code: 
links.getScriptableDelegate().doEvent("download");				

resp = webConversation.getCurrentPage();

System.out.println(resp.getURL().toString());

The string "download" is the function and now I haven't any error or exception, but the url is the same, it isn't change....

I don't know how I can resolve this problem. :(

Yes. Never used it (don't do JS). http://www.jsunit.net/

The other option would be to use that funky looking Google Web Toolkit. That looks as if you would write your JS in Java, and unit test it with jUnit.

How can I use it?
Can you give me an example?

Edit:
may be that i have found a solution...
There is a mozilla's project, it's name is Rhino, with I can run a javascript function in a java class.
Attention, in HttpUnit pakaje you have js.jar, may be that there are some errors and your java code isn't validated. I have change HttpUnit's js.jar with Rhino's js.jar and now I haven't compile error.
My next point is to try my new java code...
