// This test checks that calling `net.connect` internally calls
// `Socket.prototype.connect`.
//
// This is important for people who monkey-patch `Socket.prototype.connect`
// since it's not possible to monkey-patch `net.connect` directly (as the core
// `connect` function is called internally in Node instead of calling the
// `exports.connect` function).
//
// Monkey-patching of `Socket.prototype.connect` is done by - among others -
// most APM vendors, the async-listener module and the
// continuation-local-storage module.
