This commit introduces integration between MockMvc and HtmlUnit, thus
simplifying end-to-end testing when using HTML-based views and enabling
developers to do the following.
- Easily test HTML pages using tools such as HtmlUnit, WebDriver, & Geb
without the need to deploy to a Servlet container
- Test JavaScript within pages
- Optionally test using mock services to speed up testing
- Share logic between in-container, end-to-end tests and
out-of-container integration tests
