ngAria is an external module (not part of angular core). Hence, it doesn't have access to the private methods, such as camelCase (which is not a jqLite function btw).

This change will make ngAria tests fail.

@gkalpak yes. I just notice after the CI runs.
I'm going to close this an open another one.

@cironunes: Great (not sure what's going to be in that other one; not something camelCase-related I suppose).

BTW, you can run the tests locally and detect such errors before submitting PRs.

@gkalpak I opened another one because now the patch is a little more than just trying to reuse camelCase from jqLite.

Yeah yeah, I'm used to do grunt autotestwhich doesn't run test:modules(which test the external modules).

BTW this is the new one #10337
