主講內容：A program is said to be non-testable if the correctness of its outputs cannot be verified. Since non-testable programs are frequently encountered, a challenging problem has been how to test them. In this seminar, we present a simple, yet effective, methodology, metamorphic testing, which alleviates this challenge. Although it may not be possible to verify the correctness of any particular input of a non-testable program, we may be able to identify relations that should hold between certain inputs and relevant outputs, and through the verification of these relations (which are known as the metamorphic relations), we are able to test the non-testable programs. Although the concept of metamorphic testing is very simple, its scope of applicability is quite extensive, and not restricted only to software testing. This seminar will cover several aspects of metamorphic testing, including the application of metamorphic testing to various types of non-testable programs, the formation of a theory for metamorphic testing, as well as the integration of metamorphic testing with other techniques.
