// Important note on these tests:
//
// The way the Zulip hotkey tests work is as follows. First, we set
// up various contexts by monkey-patching the various hotkeys exports
// functions (like overlays.settings_open). Within that context, to
// test whether a given key (e.g. `x`) results in a specific function
// (e.g. `ui.foo()`), we fail to import any modules other than
// hotkey.js so that accessing them will result in a ReferenceError.
//
// Then we create a stub `ui.foo`, and call the hotkey function. If
// it calls any external module other than `ui.foo`, it'll crash.
// Future work includes making sure it actually does call `ui.foo()`.
