We have a fake that we use for testing at internal/test/ NewFakeCli()
You can change prettyPrintInfo() to accept a the command.Cli interface instead of the struct

I would recommend moving these sample texts to "golden files" (files in ./testdata relative to this package directory) and using gotestyourself/golden.Assert() to compare them. There are a bunch of example in this repo and the godoc is here: https://godoc.org/github.com/gotestyourself/gotestyourself/golden
This will make it easier to update and maintain the expected result, and it also uses difflib to give you a nice multiline diff when there are failures as long as you use the string version (not bytes). Comparing bytes gives you a diff of an array of uint8 which is impossible to debug.

Using the fake this would be assert.Equal(t, "", cli.ErrBuffer().String())

Please make this a separate test function TestPrettyPrintInfoWithSwarm() which removes the need for this comment

Following our testing guidelines (which we just merged), this should be TestPrettyPrintInfoNoSwarm()

I would just write out the exact file and compare using golden instead of doing a replace
cli/command/system/info.go
Outdated

If this is just because of the test, I think you can revert this. Using the FakeCli should give you a default config file I believe.

Thanks for the review @dnephin! I think I've addressed all the comments, and added a test for the warnings since the golden testdata files makes that way easier. |
Currently, the only way to tell if the cluster is autolocked is to attempt to unlock or get the unlock key. The info is already available on the API for
docker info, so also include it in the text output on the CLI.cc @friism
