Thread: Set headers for HttpServletRequest object?

hey, I've written a web application and I have methods which take in
a HttpServletRequest object and process the request headers.

How can I test my methods which take in HttpServletRequest object? I need to set the values of the headers, usually this is done by an external party but when I'm testing I need to manually set attributes and corresponding values. So is there a way to set these headers manually for testing purposes? or can you suggest some way I can write my test cases?

Thanks

Well in your unit testing you could fire up a jetty webserver and then actually fire off a proper request and let it all work on its own. However you could also create a class that implements the HttpServletRequest interface and pass that object in.

// Json

thanks, I can write a class to implement that interface but what methods do I then call in order to set the values of the request headers? I can see there's a getHeaders() method of HttpServletRequest but there's no setHeader() method. so how do I get around this?

Try response.setHeader()

You can't set any headers on the request because once you have access to the request the headers will already have been read by the web server.
