I see this pattern used in dom_storage_uitest.cc, but it looks like most of the
rest of Chromium uses an arraysize macro rather than a sentinel value.

+  void RunTests(const char** files) {
+    while (*files) {
+      RunLayoutTest(*files, kNoHttpPort);

Possibly pass the port into this function, so we don't get out of sync between
the call site which also passes it into InitializeForLayoutTest() - I can see us
changing this to kHttpPort at some future time as the security model around IDB
vs. file: evolves.

+      ++files;
+    }
+  }
+
+  FilePath test_dir_;
+};
+
+TEST_F(IndexedDBUILayoutTest, LayoutTests) {
+  InitializeForLayoutTest(test_dir_, FilePath(), kNoHttpPort);

e.g.:
const int port = kNoHttpPort;
InitializeForLayoutTest(test_dir_, FilePath(), port);
AddJSTestResources();
RunTests(kLayoutTestFileNames, port);

+  AddJSTestResources();
+  RunTests(kLayoutTestFileNames);
+}
