The invention provides a test script generation method and device. The test script generation method includes: acquiring an original test script corresponding to a test scene and a test script which has passed a test; reusing a test program in the acquired test script, of the same object element to be tested if each object element to be tested in the original test script is identical to the corresponding object element to be tested in the acquired test script; and modifying a test program of the object element to be tested in the original test script according to the test program of the object element to be tested in the acquired test script if at least one object element to be tested is different. The acquired test script passes the test, the test program of the object element to be tested in the acquired test script passes the test, and in this way, for an object element to be tested, identical to the object element to be tested in the acquired test script, the modifying frequency of the test program corresponding to the object element to be tested can be lowered, the test script generation speed is improved, and the test efficiency is improved.
