+ * Test suite for Android's default ProxySelector implementation. The purpose of these tests

[Yaron, 2012/09/07 01:05:44]

This whole comment seems misplaced

+ * is to check that the behaviour of the ProxySelector implementation matches what we have
+ * implemented in net/proxy/proxy_config_service_android.cc.
+ *
+ * IMPORTANT: These test cases are generated from net/android/tools/proxy_test_cases.py, so if any
+ * of these tests fail, please be sure to edit that file and regenerate the test cases here and also
+ * in net/proxy/proxy_config_service_android_unittests.cc if required.

comment these are copied from net_error_list.h and need to be manually kept in
sync

This isn't true.

+    public void testExampleErrorDefined() throws Exception {
+        assertEquals(IO_PENDING_ERROR, NetError.ERR_IO_PENDING);
+        assertEquals(FAILED_ERROR, NetError.ERR_FAILED);
+    }
+}
