How to use the nock.activeMocks function in nock

/// .persist()
scope = nock('http://example.test')
  .persist()
  .get('/')
  .reply(200, 'Persisting all the way')

/// .pendingMocks()
strings = scope.pendingMocks()
strings = nock.pendingMocks()
if (!scope.isDone()) {
  console.error('pending mocks: %j', scope.pendingMocks())
}
console.error('pending mocks: %j', nock.pendingMocks())

/// .activeMocks()
nock.activeMocks() // $ExpectType string[]
nock('http://example.test').activeMocks() // $ExpectType string[]

// Logging
google = nock('http://example.test').log(console.log)

// Restoring
nock.restore()

// Enable/Disable real HTTP request
nock.disableNetConnect()
nock.enableNetConnect()

// using a string
nock.enableNetConnect('example.test')

// or a RegExp
