A growing number of new technologies are used in test development. Among them, automatic test generation, a promising technology to improve the efficiency of unit testing, currently performs not satisfactory in practice. Test recommendation, like code recommendation, is another feasible technology for supporting efficient unit testing and gets increasing attention. In this paper, we develop a novel system, namely HomoTR, which implements online test recommendations by measuring the homology of two methods. If the new method under test shares homology with an existing method that has test cases, HomoTR will recommend the test cases to the new method. The preliminary experiments show that HomoTR can quickly and effectively recommend test cases to help the developers improve the testing efficiency. Besides, HomoTR has been integrated into the MoocTest platform successfully, so it can also execute the recommended test cases automatically and visualize the testing results (e.g., Branch Coverage) friendly to help developers understand the process of testing. The demo video of HomoTR can be found at https://***/_227EfcUbus.

Increasingly, industrial robots are being used in production systems. This is because they are highly flexible machines and economically competitive with human labor. The problem is that they are difficult to program. Thus, manufacturing system designers are looking for more intuitive ways to program robots, especially using the CAD drawings of the production system they developed. This paper presents an industrial application of a novel CAD-based off-line robot programming (OLP) and simulation system in which the CAD package used for cell design is also used for OLP and robot simulation. Thus, OLP becomes more accessible to anyone with basic knowledge of CAD and robotics. The system was tested in a robot-assisted sheet metal bending cell. Experiments allowed identifying the pros and cons of the proposed solution.
