Context: COVID-19 pandemic has impacted different business sectors around the
world. Objective. This study investigates the impact of COVID-19 on software
projects and software development professionals. Method: We conducted a mining
software repository study based on 100 GitHub projects developed in Java using
ten different metrics. Next, we surveyed 279 software development professionals
for better understanding the impact of COVID-19 on daily activities and
wellbeing. Results: We identified 12 observations related to productivity, code
quality, and wellbeing. Conclusions: Our findings highlight that the impact of
COVID-19 is not binary (reduce productivity vs. increase productivity) but
rather a spectrum. For many of our observations, substantial proportions of
respondents have differing opinions from each other. We believe that more
research is needed to uncover specific conditions that cause certain outcomes
to be more prevalent
