// NOTE: These tests are not runnable from a headless environment such as
// Docker or a CI pipeline due to the DBus "prompt" interface being called
// by the underlying go-libsecret when creating and unlocking a keychain.
//
// TODO: Investigate a way to automate the prompting. Some ideas:
//
//  1. I've looked extensively but have not found a headless CLI tool that
//     could be run in the background of eg: a docker container
//  2. It might be possible to make a mock prompter that connects to DBus
//     and provides the Prompt interface using the go-libsecret library.
