my physics textbook, "Giancoli...", stated this
If $q$ is positive, [the force and electric field] point in the same direction. If $q$ is negative, [the force and electric field] point in opposite directions.
But in a previous paragraph, it had also stated:
We see that the electric field at any point in space is a vector whose direction is the direction of the force on a tiny positive test charge at that point, and whose magnitude is the force per unit charge
If the electric field is in the direction of the force on the positive test charge, why would the force and electric field be in opposite directions if $q$ is negative?
Picture if more context is needed:
