The tests are now split into individual files for each command. The separation isn't perfect as many tests make use of multiple commands. In particular `init`, `backup`, `check` and `list` are used by a larger number of test cases. Most tests now reside in files name cmd_<name>_integration_test.go. This provides a certain indication which commands have significant test coverage.
