Testing using real device
When adopting continuous delivery (CD) successfully, teams strive to make the various test environments look as close to production as possible. This allows them to avoid bugs that would otherwise only show themselves in the production environment. This remains just as valid for embedded and Internet of Things software; if we don't run our tests in realistic environments we can expect to find some bugs for the first time in production. Testing using real devices helps avoid this issue by making sure the right devices are available in the CD pipeline.
