I'm noticing in the test that cookies.session is already decoded: headers.Cookie is 'session=aloho%25eamora', while cookies.session is 'aloho%eamora'. Can we just removing the decoding here altogether? It kind of seems like we're double-decoding. Unlike with CSRF tokens in the request body (#1260), I don't think we intended to double-decode here.

Looking at the commit history for this file, it looks like previously, the code retrieved the token from context.headers.cookie, then decoded it. Later on (in #910), the code retrieved the token from context.cookies, but it continued to decode it. If context.cookies automatically decodes, then I think when context.headers.cookie was replaced with context.cookies, the decodeURIComponent() probably should have been removed as well.

I think this promise needs to be returned in order for Mocha to wait on it.

Very possible. Do tests on line 188 and 208 need the same change?

Ah good catch, that sounds right to me. If there's an assertion in a promise chain, that assertion will only affect the success/failure of the test if the promise is returned to Mocha.

Can we just removing the decoding here altogether?

That would be great 👍 In which case, this PR would be superseded by #1290
