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.
git clone https://github.com/tc39/test262.git --depth 1npm install -g test262-harnesstest262-harness 'test262\test\**\*.js'
Run test262-harness --help for details on the various configuration options.
| Name | Action |
|---|---|
| --hostType | Type of host to run tests in. See eshost's supported hosts for available options. |
| --hostPath | Path to the host executable. |
| --hostArgs | Any additional arguments to pass to the host when invoking it (eg. --harmony, --es6all, etc). |
| -t, --threads | Run this many tests in parallel. Note that the browser runners don't work great with t > 1. |
| -r, --reporter | Selects test case result format. Currently either json or simple. Default simple. |
| --test262Dir | Optional. Root test262 directory and is used to locate the includes directory. |
| --includesDir | Includes directory. By default inferred from test262Dir or else detected by walking upward from the first test found. |
| --prelude | Path to a file to include before every test (useful for testing polyfills for example) |
