测试Jest React Link状态

Question

我有一个Category组件，可以从位置状态获取其状态

export class CategoryView extends React.Component {
  constructor(props) {
    super(props);

    this.state = this.props.location.state || {}
  }
...

发布索引/视图中与此链接的链接是

<Link role="post-category-link" to={
            {
              pathname: "categories/show/" +post.category_id,
              state:  {
                category: category || {}
                }
            }
          }>
          {category.title }</Link>

类别是实例化的类别实例。 我想测试链接“ 至”属性的选项中的状态是否填充了预定的类别。我该如何使用Jest，Jest Dom，React Testing Library和React Test Renderer做到这一点？ package.json中的相关版本：

"react": "^16.3.1",
"react-dom": "^16.3.1",
"react-router-dom": "^4.2.2"
"jest": "^24.1.0",
