Instead of printing the error to stdout return the error to the user.
This may not be a hard error (as later certificates would have passed)
but it never is good to be in a state where you have certificates in a
broken state.
Resolves#586
The tests are run in a Node.js environment, and this does not include
any browser tests. This requires the wrtc package from npm as well as a
shim which adds portions of the WebRTC API to the global scope.
Some tests introduced here can be combined when differences between the
Go API and the WASM bindings are addressed and as missing features are
added to the WASM bindings.
We can and should add more tests in the future to improve test coverage.
This should be considered the minimum number of tests reuqired to ensure
basic functionality is working.
