Sylvain, do you know how to add this in gn build? I've tried this:
"//net/data/ssl/certificates/ok_cert.pem", but it does not work (gn complains
about ok_cert.pem duplication).

[sdefresne, 2016/06/29 17:10:03]

Any application that depends on //net:test_support_bundle_data (which is a
dependency of //net:test_support IIRC) will get
//net/data/ssl/certificates/ok_cert.pem packed in the application bundle as part
of the build. The file will be accessible at
net/data/ssl/certificates/ok_cert.pem into the application bundle (which is the
correct location for such file according to the net team).

So adding the dependency on //net:test_support should be enough to get this
working with gn.

Thanks! It's already in gn bundle. I guess the answer is: no GN change is
needed.
