Test system and method for testing keys of virtual keypad

A test system for testing keys of a virtual keypad, the test system comprising:

• a reading unit configured to obtain an electrical activity of each of the keys when the key is touched;
• and
• a determination unit configured to calculate an error value of each of the keys between the obtained electrical activity and a preset performance associated with the key stored in a storage unit, determine the performance of the key is acceptable when the calculated error value is no more than a preset error value, and determine the performance of the key is a failure when the calculated error value is greater than the preset error value.
