| * Positive test for <code>ServletContext.getResource()</code> as well as |
| * <code>ClassLoader.getResource()</code>. The URL returned by |
| * these calls is then opened with <code>url.openStream()</code> |
| * in order to ensure that the correct data is actually read. |
| * Operation is controlled by query parameters: |
| * <ul> |
| * <li><strong>mode</strong> - Use <code>context</code> for servlet context |
| * test, or <code>class</code> for class loader test. [context]</li> |
| * <li><strong>path</strong> - Resource path to the requested resource, |
| * starting with a slash. [/WEB-INF/web.xml]</li> |
| * <li><strong>stringify</strong> - If set to any arbitrary value, the URL |
| * returned by getResource() will be converted to a String and then back |
| * to a URL before being opened. [not set]</li> |
| * </ul> |
