+Testing
+-------
+
+The meta-java layer may be tested using oeqa's runtime image tests. The easiest
+way is to add the following configuration to your local.conf:
+
+SANITY_TESTED_DISTROS=""
+TEST_IMAGE = "1"
+
+Then you should be able to use the open{jre,jdk}-{7,8}-test-image recipes.
+Furthermore you could also include the tests provided in lib/oeqa/runtime/cases
+into your test image. More information on image testing is available at:
+
+        https://wiki.yoctoproject.org/wiki/Image_tests
