nit: Update this comment since the container's tests are split into container
and container filter.

   extraLibraries: PolymerTest.getLibraries(ROOT_PATH).concat([
     'issue_banner_tests.js',
     'media_router_container_tests.js',
+    'media_router_container_filter_tests.js',
     'media_router_header_tests.js',
     'media_router_search_highlighter.js',
     'route_details_tests.js',
   ]),
 };
 
 // Runs all tests.

nit: Remove this comment since tests are separated.

-// TODO(crbug.com/590177, crbug.com/582649): This test is disabled, as it

naming suggestion: IssueBanner. Similarly for below.

     function() {
-  // Register mocha tests for each element.
+  // Register mocha tests for the issue banner.
   issue_banner.registerTests();
+
+  // Run all registered tests.
+  mocha.run();
+});
+
+TEST_F('MediaRouterElementsBrowserTest', 'MediaRouterElementsTestContainer',
+    function() {
+  // Register mocha tests for the container.
   media_router_container.registerTests();
+
+  // Run all registered tests.
+  mocha.run();
+});
+
+TEST_F('MediaRouterElementsBrowserTest',
+    'MediaRouterElementsTestContainerFilter',
+    function() {
+  // Register mocha tests for the container filter.
+  media_router_container_filter.registerTests();
+
+  // Run all registered tests.
+  mocha.run();
+});
+
+TEST_F('MediaRouterElementsBrowserTest', 'MediaRouterElementsTestHeader',
+    function() {
+  // Register mocha tests for the header.
   media_router_header.registerTests();
+
+  // Run all registered tests.
+  mocha.run();
+});
+
+TEST_F('MediaRouterElementsBrowserTest',
+    'MediaRouterElementsTestSearchHighlighter',
+    function() {
+  // Register mocha tests for the search highlighter.
   media_router_search_highlighter.registerTests();

+  // Run all registered tests.
+  mocha.run();
+});
+
+TEST_F('MediaRouterElementsBrowserTest', 'MediaRouterElementsTestRouteDetails',
