Testpass don't work with esm

[jimmywarting]

i got this small setup:

{
  "name": "test",
  "type": "module",
  "devDependencies": {
    "testpass": "^0.9.12"
  }
}

// test.js
import tp from 'testpass'

tp.test('foo', t => {
  t.eq(123, 123)
})

---

when i exec: node test.js then i get a error saying:

type-error % node test.js
/CODE/node_modules/testpass/src/context.js:63
    throw Error(`Test module was not loaded properly: "${path}"`)
          ^
