How to use the testcafe.t.setTestSpeed function in testcafe

export default async (): Promise => {
  // get the config that was injected into the fixture/test context by the feature
  const config: Config = getCurrentConfig(t);

  // get the page object model that was injected in the context
  const inputData = t.ctx.inputData as PageModel;

  const value = inputData.name || '';

  await t
    .setTestSpeed(config.testSpeed)
    .hover(selector.userNameInputBox)
    .expect(selector.userNameInputBox.hasAttribute('disabled'))
    .notOk()
    .click(selector.userNameInputBox)
    .typeText(selector.userNameInputBox, value, { replace: true })
    .pressKey('tab');
};
