test: add test-262 script

[dnalborczyk]

adds test-262 runner. based on: https://github.com/acornjs/acorn-class-fields/blob/89a1c7a6795e0fdac3e8fc8587ee6e1b9ea67dd0/run_test262.js also bumped deps and added LTS versions to ci.

test-262 import assertions:
tc39/test262#2980

test-262 json modules:
tc39/test262#2999

added the failing tests to the whitelist: 3ead374#diff-0760fe08ac8e4dce6d416f554fcb99850cb731a9df9d37cd3743b9bf7bf80a52R14

not sure if all test-262 issues can be fixed and subsequently removed from the whitelist?

The workflow is not valid. .github/workflows/main.yml (Line: 1, Col: 1): Unexpected value 'ame'

do you have any idea where that's coming from?

I forgot to add a reference to the test262 repository: https://github.com/acornjs/acorn-class-fields/blob/89a1c7a6795e0fdac3e8fc8587ee6e1b9ea67dd0/package.json#L30 . I pinned it to the current latest commit.

not sure if that's the issue tho, the ci is not running (needs approval). I got the ci running in the forked repo. I [temporary] removed package-lock and yarn-lock, and changed the ci to use install instead of ci. there seems to be a different issue now. still looking ...

[xtuc]

it failed with now

I can help debug later today.

I'm guessing the build step is missing, otherwise the lib folder does not exist and therefore the main entry point for cjs is invalid. I'll give it a try.

[dnalborczyk]

yap, that was the issue. 🙌

[dnalborczyk]

the current test-262 returns the following:

> acorn-import-assertions@1.7.6 test:test262 /home/runner/work/acorn-import-assertions/acorn-import-assertions
> node run_test262.js

Testing complete.
Summary:
 ✔ 31 valid programs parsed without error
 ✔ 7 invalid programs produced a parsing error
 ✔ 4 invalid programs did not produce a parsing error (and allowed by the whitelist file)
 ✔ 127 valid programs produced a parsing error (and allowed by the whitelist file)
 ✔ 80495 programs were skipped
