Test Transplantation through Dynamic Test Slicing

open access: yes2022 IEEE 22nd International Working Conference on Source Code Analysis and Manipulation (SCAM), 2022
Abstract: Previous research has demonstrated that the test coverage of libraries can be expanded by using existing test inputs from their dependent projects. In this paper, we propose an algorithm for test transplantation based on test slicing. The algorithm extracts test inputs, isolates them by creating mocks, and then transplants the test code onto ...
