ByPlaceholderText

getByPlaceholderText, queryByPlaceholderText, getAllByPlaceholderText, queryAllByPlaceholderText, findByPlaceholderText, findAllByPlaceholderText

API

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

這會搜尋所有具有 placeholder 屬性的元素，並找到一個符合給定的 TextMatch 的元素。

<input placeholder="Username" />

原生

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')

Angular

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

await render(MyComponent)
const inputNode = screen.getByPlaceholderText('Username')

Cypress

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

注意

placeholder 並不是 label 的好替代品，所以你通常應該改用 getByLabelText。
