Is there no way to test this CL?

File Source/modules/crypto/SubtleCrypto.cpp (right):

https://codereview.chromium.org/21016005/diff/6001/Source/modules/crypto/Subt...
Source/modules/crypto/SubtleCrypto.cpp:133: // FIXME
Rather than an empty FIXME comment, you can call the notImplemented() function. 
That doesn't do anything, but it's a more accurate description of what's going
on here.

I can add testing for this one, however it will mean implementing some more
extra as part of this CL.

(I have been trying to keep my changelists smaller so they are easier to
review.)

I am happy to add to this one and have more complete layout tests as part of it
if you prefer. Or I can chunk it into 2 changelists

Done.

LGTM

I prefer small CLs if it's not too much overhead for you.  The ideal CL is a
testable unit, but I trust you'll include tests in your next CL.
