An experimental Node-based test262 harness. Once this harness has stabilized, I plan to push to include it by default in official test262.
Requires Node 6 or above.
- Clone test262 locally:
git clone https://github.com/tc39/test262.git --depth 1 cd test262 - Install test262-harness:
npm install -g test262-harness - Run some tests!
test262-harness test/**/*.js
Run test262-harness --help for details on the various configuration options.
