[Arun Ak]

Hi All,

I had written struts2 action class which export pdf file. it works perfectly fine, now I want to write down Junit test case for this action class.Can any one know how to write unit test case for this action class.

my action

-----
----
response.setContentType("application/xml");
response.setHeader("Content-disposition","attachment;filename=Result.crwl");
----
---
try {
				OutputStream ops = response.getOutputStream();
				exporter.toXML(tsksList, ops);
				ops.close();
			} catch (IOException e) {
				log.error("unable to get output stream", e);
				addActionError(e);
			}

Arun

Pass in an HttpServletResponse implementation that provides an output stream and saves the content-type and other headers, call your action method then verify your object!

Personally, I'm not sure I'd test it this way. I'd test the file generation, but I don't think I'd test the application container--at least not with a unit test.

Also, I would have used the "stream" result type, and avoided all the complicated testing to begin with.
