The online help for NIntegrate it says:

NIntegrate[f,{x,x0,x1, ... , xk}] tests for singularities at each of the
intermediate points xi.  If there are no singularities, the result is
equivalent to an integral from x0 to xk.  You can use complex numbers
to specify an integration contour in the complex plane.

I can't find a place where it's documented, but it seems Integrate can
be used the same way.
