Beyond Unit-Testing in Search-based Test Case Generation: Challenges and Opportunities

Over the last decades, white-box search-based techniques have been applied to automate the design and the execution of test cases. While most of the research effort has been devoted to unit-level testing, integration-level test case generation requires to solve several open challenges, such as the combinatorial explosion of conditions or pre-condition failures. This paper summarizes these challenges in white-box testing and highlights possible research directions to overcome them.Software Engineerin
