The cmd subdirectory

The cmd subdirectory contains various tools and commands to support development and operations, as well as end-to-end tests that involve multiple actors, services, or external dependencies; for example, testing a microservice via its client library.

At the moment, it only contains a single end-to-end test for the social graph service:

$ tree cmd
cmd
└── social_graph_service_e2e
    └── social_graph_service_e2e.go
