Notes: This solver is not a solver and does not converge to a solution. SNESTEST checks the Jacobian at three points: the 0, 1, and -1 solution vectors. After doing these three tests, it always aborts with the error message "SNESTest aborts after Jacobian test". No other behavior is to be expected. It may be similarly used to check if a SNES function is the gradient of an objective function set with SNESSetObjective().
