nit: i would probably leave this out, or put it in //media/mojo/BUILD.gn. that
way the path isn't obscured.  Dependencies would look like

//media/mojo

instead of

//media:mojo

so it's not any more characters

+  deps = [
+    "//media/mojo/interfaces",
+    "//media/mojo/services",
+  ]
+}
+
+group("mojo_tests") {

[jamesr, 2014/09/17 21:55:49]

similarly this could be //media/mojo:tests

+  testonly = true
+  deps = [
+    "//media/mojo/services:tests"
+  ]  
+}
+
 test("media_unittests") {
   sources = [
     "cdm/aes_decryptor_unittest.cc",
