Understanding and augmenting scientific software testing practices
Get PDFScientific software can be broadly defined as software written to aid in conducting scientific research activities. As this software is often written by the scientists themselves, who often learned programming to build that software, some important aspects of software development may get less attention than they would have gotten on enterprise software developed by programmers. One area of development that often gets overlooked in this regard is testing. Thus, in this study, we seek to better understand the testing processes and propose methods to improve the effectiveness of those tests. We begin with examining the software\u27s Continuous Integration/Delivery practices. This is primarily done through GitHub Actions, which can be used to automate testing. Based on this, we examined the GitHub Actions of several scientific software practices of various sizes and scientific domains. Results of our study show that, even among the variety in the software, many aspects of their GitHub Actions Workflows are shared. We then conducted a study to evaluate the fault detection effectiveness of the tests in scientific software. Our results show that there do exist common deficiencies in testing among this scientific software, such as low if-statement branch coverage or low edge case sensitivity and lack of thorough testing of mathematical calculations. These shortcomings can potentially be improved through known testing methods. Finally, Based on our findings, we propose and explore a testing method called metamorphic testing, which makes use of necessary properties of a function that identify relationships between a that function\u27s input and its output. We added metamorphic tests to the software\u27s test suites, and found as much as a 10\% improvement on mutation testing results among some types of mutations. The results imply that the improvements made by metamorphic testing can be even further improved when written by someone with domain knowledge
Development and characterization of ceramic devices for capillary action in microgravity for the purpose of growing vegetables in space
Get PDFThe future of humanity is often rendered in spectacular visions of a multiplanetary civilization with a booming space economy. Reaching this reality requires addressing one of the core needs of survival: food. Porous ceramics used for Passive Porous Tube Nutrient Delivery Systems (PPTNDS) offer a promising solution. In microgravity environments such as the International Space Station (ISS), fluid dynamics and liquid coagulation do not support conventional agricultural practices. Porous ceramic materials present a solution that enables nutrient solution diffusion via capillary action.
In this research, it was determined that extruding a wadding ceramic tube and sintering it at 1900 °F for 6 hours matches the porosity, water uptake, and pore size requirements prescribed by NASA. This material not only outperformed NASA’s current alumina-based device but also offered higher flexibility for recipe optimization. Additionally, it is substantially cheaper than their current supplier
