I have to write a program through which I can automate the testing of multiple websites at a time. Are there certain xml based API which can give the result in xml format and I can store it using the progam by writing the logic.
Just be careful if you are going to be automating against the public instance - if you submit too many tests you will get blocked. It’s mostly intended for automating private instances where you run your own infrastructure.
Would this work for you?
