In the test method according to the present invention, a first solution in which a coloring matter is dissolved is dispensed to a first container in advance by a first dispensing probe, a second solution in which a coloring matter is not dissolved is dispensed to a second container in advance by the first dispensing probe and then the first solution and the second solution are respectively sucked and discharged by a second dispensing probe. After that, a surface state of the second dispensing probe is evaluated by acquiring an amount of the coloring matter collected by the second solution (see FIG. ).
