Depending on your specific business needs, there are three software testing outsourcing models to choose from - onshore, offshore, and nearshore. Onshore outsourcing is where you outsource the software testing to an external company located in the same country but not necessarily in the same city as yours. Contrarily, offshore outsourcing is where you hand off the testing to a company located in another country, even halfway across the world, which works virtually with you. In nearshore outsourcing, you’d be employing an external team in a neighboring country, typically having a 3-hour time zone difference.
