Top Software Testing Companies in 2020: 30 QA Providers to Keep an Eye On

According to Pew Research Center, 83% of US adults were using smartphones in 2019, and 74% of them were also desktop or laptop owners. Moreover, surprising four and a half billion people around the globe, which is 59% of the total world population, were internet users.
