Program synthesis is an automated programming technique that automatically constructs a program which satisfies given specifications. SyPet is a recently published novel component-based synthesis tool that assembles a straight-line Java method body that invokes a sequence of methods from a given set of libraries to implement desired functionality that is defined by a given test suite. In this report, we experimentally evaluate the correctness and performance of the publicly available SyPet implementation, at the black-box level, focusing on the size of test suites. We then demonstrate how SyPet can be extended to support some other applications, such as synthesizing non-straight-line methods and program repair. Finally, we conjecture an alternative technique that is conceptually simpler for synthesizing straight-line methods and present a few initial experimental results.Electrical and Computer Engineerin
