It’s weird that this service is listed as a separate thing at all. I always thought if I pay developers for a product, it would already be tested and polished.
Well, situations vary, and maybe this is about testing to check if software is still doing its job. Software or some kind of equipment. If you visit the SPD technology's site, they have services for testing software and equipment, but they also offer lots of services for automating workflows not just with AI but with software robots too.
