Support function mocking on Node.js test runner

The node:test module supports mocking during testing via a top-level mock
object.

test('spies on an object method', (t) => {
  const number = {
    value: 5,
    add(a) {
      return this.value + a;
    },
  };
  t.mock.method(number, 'add');

  assert.strictEqual(number.add(3), 8);
  assert.strictEqual(number.add.mock.calls.length, 1);
});

fs.watch recursive support on Linux

fs.watch supports recursive watch using the recursive: true option.

const watcher = fs.watch(testDirectory, { recursive: true });
watcher.on('change', function(event, filename) {
});
