This patch introduces assertPromiseFulfills and assertPromiseFulfills as a replacement for assertPromiseResult because it’s more JavaScript-y. BUG=v8:6921 R=ahaas@chromium.org Also-By: ahaas@chromium.org Change-Id: I2f865dba3992ddf3b58987bf0b376d143edb5c31 Reviewed-on: https://chromium-review.googlesource.com/718746 Commit-Queue: Andreas Haas <ahaas@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#48578}
