The direction of the field is equal to the force direction, unless the test charge has a negative charge, then the direction is exactly opposite of the force direction. Well, the force on a particle in a uniform electric field is F=qE.
For example, if you place a positive test charge in an electric field and the charge moves to the right, you know the direction of the electric field in that region points to the right.
