I think you're missing 'api_test' in the path here. 

BTW, you can simplify this slightly - the test_data_dir_ member variable that
you inherit from ExtensionApiTest  via SocketApiTest is already pointing at
src/chrome/test/data/extensions/api_test/, so you should be able to just do:

app_dir_ = test_data_dir_.AppendASCII("socket/ppapi/newlib");

Thanks! I updated the output path that the test data is written to and the path
here.
Here app_dir_ is a location inside our output directory. It is not part of
src/chrome/test/data/extensions/api_test/.

Oops, sorry, I missed that.
