Have any one of you came across data compression for reducing bandwidth consumption. The compression is being done for requests and response between server and browser.
Could you load test with data compression ON?
How much an impact did data compression create?
As a developer I have developed systems that use data compression. However in those cases there was not a necessity for automated testing. But what I can say is that it would probably not be possible to use datapools without a considerable amount of work. Other than that it should be fine.
I'm doing it as we speak. Datapools aren't a problem because the only stuff that gets compressed is what is coming FROM the webserver. The difficulty comes in if you need anything from the _response file (oops Rational term - anything from the server response). THEN you have have an issue. What are you trying to test with what tool? Most tools do not de-compress on the fly - though I think they should (Tool vendors - are you reading this? hint, hint).
For us the response as well request both are being compressed.
I definitely need to look at response and then compress the request also.
I am not doing that right now and I have asked developers to turn off compression. Basically I would have to incorporate the program used by application to compress/decompress. Further tool vendors would need to provide programmatic interface to manipulate the response and request.

To get around the compression you may just be able to change your browser setting to use HTTP 1.0 - it doesn't support compression. One of two things will happen, it will over-ride the compression, or it will make the app stop working. The tests might not be as realistic, but it's not really THAT far off if you "do your homework" on the network and webserver related differences.
