The method includes obtaining a response information set for a touch operation according to a response of a touchscreen to the touch operation in a preset area, and determining that a working state of the touchscreen is abnormal if the response information set for the touch operation is inconsistent with a preset response information set, where the preset response information set is the response to the touch operation in the preset area when the working state of the touchscreen is normal. The embodiments of the present invention are applicable to the field of touchscreen technologies. ## Claims ### Claim 1 A method for testing a capacitive touchscreen, comprising: obtaining a response information set for a touch operation according to a response of a touchscreen to the touch operation in a preset area; and determining that a working state of the touchscreen is abnormal if the response information set for the touch operation is inconsistent with a preset response information set, wherein the preset response information set is the response to the touch operation in the preset area when the working state of the touchscreen is normal. ### Claim 2 (depends on 1) The method according to claim 1, wherein: the preset area is in a display area of the touchscreen; the response information set for the touch operation comprises the number of touch points or a position of a touch point, wherein the touch point is on the touchscreen responding to the touch operation in the preset area; and the preset response information set comprises the number of preset touch points or a position of a preset touch point when the working state of the touchscreen is normal, wherein the preset touch point is on the touchscreen responding to the touch operation in the preset area. ### Claim 3 (depends on 2) The method according to claim 2, further comprising, after an intersection set of the response information set for the touch operation and the preset response information set is obtained, acquiring a complementary set of the intersection set in the preset response information set, and determining that a touch point corresponding to a position of a touch point comprised in the complementary set is disconnected. ### Claim 4 (depends on 2) The method according to claim 2, wherein the response information set for the touch operation comprises a position of a first touch point, wherein the method further comprises determining that a touch point corresponding to the position of the first touch point is shorted, and wherein the position of the first touch point is a same position that is of an even number of touch points and comprised in the response information set for the touch operation. ### Claim 5 (depends on 3) The method according to claim 3, wherein the response information set for the touch operation comprises a position of a first touch point, wherein the method further comprises determining that a touch point corresponding to the position of the first touch point is shorted, and wherein the position of the first touch point is a same position that is of an even number of touch points and comprised in the response information set for the touch operation. ### Claim 6 A method for testing an electronic device, comprising: obtaining a response information set for a touch operation according to a response of a touchscreen to the touch operation in a preset area, wherein the preset area is a non-display area of an electronic device, and the response information set for the touch operation comprises a position of a touch point in a display area responding to the touch operation; and determining that a working state of the non-display area is abnormal if the response information set for the touch operation is inconsistent with a preset response information set, wherein the preset response information set is a position of a preset touch point in the display area. ### Claim 7 (depends on 6) The method according to claim 6, wherein the non-display area is a key that can be used for touching on the electronic device. ### Claim 8 An apparatus for testing a capacitive touchscreen, comprising: a touchscreen; and a processor; wherein the touchscreen is configured to respond to a touch operation in a preset area, and to send response information to the processor; and wherein the processor is configured to receive the response information sent by the touchscreen, to obtain a response information set for the touch operation, and to determine that a working state of the touchscreen is abnormal if the response information set for the touch operation is inconsistent with a preset response information set. ### Claim 9 (depends on 8) The apparatus according to claim 8, wherein: the preset area is in a display area of the touchscreen; the response information set for the touch operation comprises the number of touch points or a position of a touch point, wherein the touch point is on the touchscreen responding to the touch operation in the preset area; and the preset response information set comprises the number of preset touch points or a position of a preset touch point when the working state of the touchscreen is normal, wherein the preset touch point is on the touchscreen responding to the touch operation in the preset area. ### Claim 10 (depends on 9) The apparatus according to claim 9, wherein the processor is further configured to obtain an intersection set of the response information set for the touch operation and the preset response information set, to acquire a complementary set of the intersection set in the preset response information set, and to determine that a touch point corresponding to a position of a touch point comprised in the complementary set is disconnected. ### Claim 11 (depends on 9) The apparatus according to claim 9, wherein the response information set for the touch operation comprises a position of a first touch point, wherein the processor is further configured to determine that a touch point corresponding to the position of the first touch point is shorted, and wherein the position of the first touch point is a same position that is of an even number of touch points and comprised in the response information set for the touch operation. ### Claim 12 (depends on 10) The apparatus according to claim 10, wherein the response information set for the touch operation comprises a position of a first touch point, wherein the processor is further configured to determine that a touch point corresponding to the position of the first touch point is shorted, and wherein the position of the first touch point is a same position that is of an even number of touch points and comprised in the response information set for the touch operation. ### Claim 13 (depends on 8) The apparatus according to claim 8, wherein: the preset area is a non-display area of the apparatus; the response information set for the touch operation comprises a display area responding to the touch operation; and the preset response information set comprises a position of a preset touch point in the display area. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the non-display area is a key that can be used for touching on the apparatus. ### Claim 15 (depends on 8) The apparatus according to claim 8, wherein the apparatus is a mobile terminal.
