I think you have several possibilities :

testing user interactions by real click automations: don��t know what is up todays but there were Albatross back in 2006 [1] or SeasideTesting [2]. Probably, there are other options.
Simulate client requests programmatically. You could do that in Zinc quite easily if you know the different url. Have a look at the book �� Enterprise Pharo �� [3]
BeautifulSoup is called Soup and is accessible through the catalog or SmalltalkHub [5]. Works well (note to pharoers: but I think that be nice to have an interface like scrappy instead).

Now, as you say "Its a simple socket bridge with which pharo can communicate with python and say "hey python do this for me and return me the result ��.

I��d say the second option with Zinc seems to be the best approach, start with the chapter about client but you��ll probably need the server chapter so as to get bidirectional connections. My guess�� and interesting project btw :)

HTH,
