which english test to take for getting the certificate faster without showing the passport in UK ?

My situation:
My passport is with UKBA for an another application, and I'd like to apply for tier 2 general as soon as I get the passport back. I know I've to take an English test for that..

I've looked at cambridge ESOL which doesn't need passport (any ID proof seems to be fine) but it seems to take around 3 months is too much of time.

IELTS seems to be giving certificate in 13 days but I need to show them the passport to take exam! which I can't.

I understand my situation is complex and I've tried going through the exams listed in the approved list of tests in UKBA website but can't find (can't go through the whole list actually and contact each and everybody), still going through..

So my question here is to somebody who know which is the right test to take without showing passport in UK which gives certificate within weeks?

Pearson Academic is the answer to all the questions..

* you can write it without showing your passport
* results came to me in a day (viewable in online) [ though they guarantee results in 5 days]
* you can book just before a couple of days with additional fees.
* seems easy to me because I'm here in UK for more than a year and also prepared very well
