// TODO(monopole): Add a feature test example covering secret generation.
// WARNING: These tests use a fake file system, and any attempt to use a
// feature that spawns shells will fail, because said shells expect a working
// directory corresponding to a real directory on disk - see
// these lines in secretfactory.go:
// cmd := exec.CommandContext(ctx, commands[0], commands[1:]...)
// cmd.Dir = f.wd
// Worse, the fake directory might match a real directory on the your system,
// making the failure less obvious (and maybe hurting something if your secret
// generation technique writes data to disk). So no use of secret generation
// in these particular tests.
// To eventually fix this, we could write the data to a real filesystem, and
// clean up after, or use some other trick compatible with exec.
