stub-obj-proxy

Make stub objects using Proxies, supporting null-safe deep path access, function calls, for loops, etc.

Useful for mocking out objects in tests, e.g., the window global.

import stubObjProxy from 'stub-obj-proxy'

global.window = stubObjProxy()

console.log(window.a.b.c)

window.a.b.c = 'foo' // Note: sets do not persist

for (let e in window.a.b.c) {
  console.log(e)
}

window.a.b.c.hasOwnProperty('ok') // true

'ok' in window.a.b.c // true
