我正在尝试对我的 React 组件之一进行单元测试，但是 Enzyme 的浅渲染方法说它在组件中找不到元素。该组件根据身份验证道具呈现不同的导航链接。

导航组件：

    class Header extends Component {

      renderLoginNav() {
        switch(this.props.auth) {
            case null:
                return;
            case false:
                return (
                    <li key={ 1 }><a className="nav-link" href="/auth/google" 
                     id="google">Login</a></li>
                );
            default: 
                return [
                    <li key={ 2 } className="nav-item">
                        <a className="nav-link" href="/lists">Dashboard</a></li>,
                    <li key={ 3 } className="nav-item">
                        <a className="nav-link" href="/credits">Credits</a></li>,
                    <li key={ 4 } className="nav-item">
                        <a className="nav-link" href="/api/logout">Logout</a></li>
                ];
        }
    }
    render() {
        return (
                <nav>
                    <ul>
                        {this.renderLoginNav()}
                    </ul>
                </nav>
        );
    }
}
function mapStateToProps(state) {
    return {
        auth: state.auth
    } …

我无法执行量角器测试。无论我在启动 webdriver 后输入什么，它都会显示“试图很好地关闭”。
