Remove this test?

This will fail if the page generates any asserts or console errors. I prefer to
have a simple test like this so that it's clear that there is a problem
independent e.g. of any page or section loading. I will add a comment.

+
+    test('basic pages', function() {
+      var page = self.getPage('basic');
+      expectTrue(!!self.getSection(page, 'appearance'));
+      expectTrue(!!self.getSection(page, 'on-startup'));
+      expectTrue(!!self.getSection(page, 'search'));
+      if (!cr.isChromeOS) {
+        expectTrue(!!self.getSection(page, 'people'));
+        expectTrue(!!self.getSection(page, 'defaultBrowser'));
+      } else {
+        expectTrue(!!self.getSection(page, 'internet'));
+        expectTrue(!!self.getSection(page, 'users'));
+      }
+    });
+
+    test('advanced pages', function() {
+      var page = self.getPage('advanced');
+      expectTrue(!!self.getSection(page, 'location'));
+      expectTrue(!!self.getSection(page, 'privacy'));
+      expectTrue(!!self.getSection(page, 'passwordsAndForms'));
+      expectTrue(!!self.getSection(page, 'languages'));
+      expectTrue(!!self.getSection(page, 'downloads'));
+      expectTrue(!!self.getSection(page, 'reset'));
+
+      if (cr.isChromeOS) {
+        expectTrue(!!self.getSection(page, 'dateTime'));
+        expectTrue(!!self.getSection(page, 'bluetooth'));
+        expectTrue(!!self.getSection(page, 'a11y'));
+      }
+    });
+  });
+
+  // Run all registered tests.
+  mocha.run();
+});
