Bill Budge b261213fcc Revert "Improve error messages for property access on null/undefined" This reverts commit `24c626c1f7`. Reason for revert: Blocks V8 roll into Chromium (changed error messages cause tests to fail): https://ci.chromium.org/p/chromium/builders/try/linux-rel/724109? Original change's description: > Improve error messages for property access on null/undefined > > Only print the property name when accessing null/undefined if we can > convert it to a string without causing side effects. > If we can't, omit the property name in the error message. > This should avoid confusion when the key is an object with toString(). > E.g. undefined[{toString:()=>'a'}] doesn't print 'read property [object > Object]' anymore, which was misleading since the property accessed would > be 'a', but we can't evaluate the key without side effects. > > Bug: v8:11365 > Change-Id: If82d1adb42561d4851e2bd2ca297a1c71738aee8 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2960211 > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > Commit-Queue: Patrick Thier <pthier@chromium.org> > Cr-Commit-Position: refs/heads/master@{#75250} Bug: v8:11365 Change-Id: Ic63f34033254f55b3871041633d84ea48586a75d Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2977374 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Commit-Queue: Deepti Gandluri <gdeepti@chromium.org> Commit-Queue: Bill Budge <bbudge@chromium.org> Reviewed-by: Bill Budge <bbudge@chromium.org> Cr-Commit-Position: refs/heads/master@{#75282}		2021-06-21 23:06:41 +00:00

JavaScript tests with expected output

Tests in test/message pass if the output matches the expected output. Message tests are particularly useful when checking for exact error messages.

Tests and their expected output must have the same filename, with the .js and .out extension.

foo.js
foo.out

All tests must end with an exception. The test runner does not handle output from multiple runs, e.g., --stress-opt. Without an exception, the output will be generated several times and the comparison will fail.

You can use a regex in the expected output instead of the exact path:

*%(basename)s:7: SyntaxError: Detected cycle while resolving name 'a'

Empty lines are ignored in the comparison, but whitespaces are not.

Exact details of the test runner are in testcfg.py.
