question: how to tell if a function has been spied/stubbed upon? (plugin development)

[boneskull]

Hi,

Working on angular-debaser, I have a situation in which I want to know if a function is a Sinon.JS stub. Currently I am checking for foo.displayName === 'stub' or foo.displayName === 'spy' but this might be flimsy, and was wondering if there was a canonical way to do it.

thanks,
Chris

Yes. Sinon itself does it here: https://github.com/cjohansen/Sinon.JS/blob/master/lib/sinon.js#L76

If anyone else finds this via Google as I did, the line referred to above is here in the history:

sinon/lib/sinon.js

Line 76 in 7910099

} else if (wrappedMethod.restore && wrappedMethod.restore.sinon) {

The same check is now in:

sinon/lib/sinon/util/core/wrap-method.js

Line 38 in a5c22f2

} else if (wrappedMethod.restore && wrappedMethod.restore.sinon) {
