With pre-season testing reduced to just two outings in 2015, Spain and Austria have been chosen as the two venues.
Last year there were four in-season outings which took place in Bahrain, Spain, Britain and Abu Dhabi, the latter taking place in the wake of the Championship.
This year, in a bid to once again cut back on costs, there will be just two separate tests.
They will be held at the Circuit de Catalunya and the Red Bull Ring, both taking place in the days after the relevant grand prix.
Both tests will be held over two days and teams will have to run drivers with less than two grand prix starts on two of the four days of testing.
