API

getByPlaceholderText(
  // If you're using `screen`, then skip the container argument:
  container: HTMLElement,
  text: TextMatch,
  options?: {
    exact?: boolean = true,
    normalizer?: NormalizerFn,
  }): HTMLElement

将搜索所有具有 placeholder 属性的元素，且匹配指定的 TextMatch。

<input placeholder="Username" />

Native

import {screen} from '@testing-library/dom'

const inputNode = screen.getByPlaceholderText('Username')

React

import {render, screen} from '@testing-library/react'

render(<MyComponent />)
const inputNode = screen.getByPlaceholderText('Username')

Cypress

cy.findByPlaceholderText('Username').should('exist')

注意

placeholder 不是 label 的良好替代品，因此你通常应该使用 getByLabelText。
