A keyboard test program generating method includes the following steps. Firstly, a first key number is received. By pressing a first key, a first key identification code corresponding to the first key is generated. The first key number is assigned to the first key so as to generate a first key conditional expression. By pressing a next key, a next key identification code corresponding to the next key is generated. A second key number following the first key number is assigned to the next key so as to generate a next key conditional expression. Afterwards, these key conditional expressions, a keyboard test program header and a keyboard test program trailer are combined together, thereby generating the keyboard test program.
