Pirelli have locked all 11 Formula One teams into one day of testing during this season, putting an end to last year's controversy.
Last season Pirelli came in for a great deal of criticism due to blow-outs and high degradation.
However, with in-season testing banned, Pirelli had to resort to private outings to try solve the problem.
This led to a lot of finger pointing as while the likes of Ferrari provided an old car for their test, Mercedes put in the laps in their 2013 challenger.
This year, though, in-season testing is back on the schedule and Pirelli have already booked dates in which to test with each of the 11 teams.
Bahrain test - 8-9 April
Day 1 Caterham
Day 2 Mercedes and Williams
Barcelona test - 13-14 May
Day 1 Sauber and Toro Rosso
Day 2 McLaren and Force India
Silverstone test - 8-9 July
Day 1 Ferrari and Lotus
Day 2 Red Bull and Marussia
