Time to make it a "real" answer :
As of Sage 8.3 (released Aug, 3, 2018), Sage implements :
fresnels_sin
(i. e. $\displaystyle\int_0^x \sin\frac{\pi t^2}{2} dt$), and
fresnels_cos
(i. e. $\displaystyle\int_0^x \cos\frac{\pi t^2}{2} dt$).
Note that Sage follows DLMF's (a. k Abramowitz & Stegun) definitions rather that the simpler ones quoted by (the start of the) Wikipedia article. Note also that this does not implement Frenel's $\cal{F}(z)=\displaystyle\int_z^\infty \textrm{e}^{\frac{1}{2}\pi i t^2} \textrm{d}t $ (left as an exercise to the reader ?).
