Abstract: Techniques for generating a test case involve: acquiring a first set of coding sequences representing a first set of test cases selected from a test case set for product testing. A test element in a test case of the test case set is coded based on the position of the test element in the element hierarchy of the test case set. The techniques further involve: generating a second set of coding sequences by performing a random variation related to at least one test element with respect to the first set of coding sequences; and generating a second set of test cases based on the second set of coding sequences. Accordingly, product testing and development may be automated, and the case set may change dynamically in a way that is adapted to product development while significantly reducing the overhead of designing and reviewing test cases throughout the product life cycle.
