An agreement has been reached for the Sakhir circuit to stage the second and third tests ahead of the 2014 campaign, whilst their race on April 6 is to be run in twilight under floodlights.
Jerez will stage the opener from January 28-31, whilst Bahrain has been given the green light to run tests from February 19-22 and then from the 27th to March 2.
With teams eager for warm weather running in pre-season, Bahrain was deemed preferable to near neighbours Abu Dhabi and Dubai.
"The idea is that you get into some temperature testing and, if you look at the Middle East, Abu Dhabi is not a good circuit for testing, and Dubai is a bit Mickey Mouse," said McLaren team principal Martin Whitmarsh, speaking in Korea ahead of this weekend's grand prix.
"The best circuit for testing out there is Bahrain, so that is why we are going there."
The race itself, however, will be the highlight for Bahrain as they follow Abu Dhabi's lead in staging a twilight event.
It had been suggested Bahrain would be a full night race, akin to that in Singapore, but it appears they have tempered such plans.
Whitmarsh added: "I think they are going to call it a twilight race.
"I've seen pictures of all the floodlights on it, so for their 10th anniversary they've got floodlights."
