babel-test262-runner's Introduction

Babel Test262

NOTE: Only linux64 and darwin64 are currently supported.

Run test262 tests on Node 0.10 using Babel 7 and core-js@3.

Installation

git clone [url of this repo] --recursive --shallow-submodules
cd babel-test262-runner
node lib/download-node

Run tests

node lib/run-tests [pattern]

[pattern] must be a substring of the path of the tests to run. For example:

node lib/run-tests arrow-function

If you want to run all the tests, run

node lib/run-tests I_AM_SURE

If you want to run against a local copy of babel repo (useful for debugging):

BABEL_PATH=../babel node lib/run-tests [pattern]

Download babel/babel master test262 artifact

node lib/download-master-artifact <optional file path>

Compare results with master

node lib/compare-results <master artifact path> <pr artifact path>

babel-test262-runner's Issues

Run all the tests

We have never done this 😛

The problem is that on my laptop (i7-8750H, 6 physical cores and 12 virtual cores, 16gb of ram) it runs 1000 tests in about 1 minute, and it heats up to 97 °C.
There are about ~70k tests, so they need to be run on a more powerful machine.

Another option is to check if they can be optimized better, but unless we get a 10x speed improvement we don't fully solve the problem.

Make the output more usable

Currently the output is just a list like this:

While it's ok if it needs to be read by machines, this Test262 runner is primarly meant for people who whant to check if Babel is compliant in some features or are looking for possible PRs.

Ideally it should generate an HTML file where users can expand different sections and it shows percentages for each section.
