Merge Risk: 🟡 Moderate · up to 21fbf

Some TypeScript consumers may fail when explicitly typed Loading prop objects omit the new style field, and the feature is not protected by a style assertion; address both before merging.

textStyle 设为可选。 BaseLoadingtextStyle 声明为必填字段,WebLoadingPropsTaroLoadingProps 均继承该字段。LoadingProps 也分别导出自这两个类型,因此直接声明 BaseLoadingLoadingProps 对象并省略 textStyle 会触发 TypeScript 类型错误。组件的 Partial<...> 参数和运行时默认值不会放宽这些导出类型。请将 textStyle 改为可选,并保留运行时默认值。

textStyle 增加样式断言。 src/packages/loading/__test__/loading.spec.tsx 中的测试只检查 .nut-loading-text 元素存在,不检查其 style。删除 style={textStyle} 后,该测试仍会通过。请传入样式并断言它到达文本元素。

test('text style test', () => {
  const { container } = render(
    <Loading textStyle={{ color: 'red' }}>加载中</Loading>
  )
  expect(container.querySelector('.nut-loading-text')).toHaveStyle({
    color: 'red',
  })
})
