No umbraco document matches the URL 'xxx'

Using umbraco7, I created a Document Type named HomePage with a corresponding Template, and then created the corresponding Content. Then I created a new Template named Test (this is an independent cshtml file without corresponding Document Type and Content nodes, and the path of the Template file is /Views/test.cshtml). When I was on HomePage add a link to Test.cshtml

<a href="/Test">test</a>

Start the project. After the browser loads the HomePage, click the a link from the HomePage page, which can be normally routed to Test.cshtml in umbraco7, but it doesn’t work properly in umbraco8. The error message is as follows,

Do I need additional configuration in umbraco8 and how to implement it? Thanks.
