    test262-parser-runner

    A test runner for running the ECMAScript Test Suite against a given parser.

    Installation

    npm i test262-parser-runner

    Usage

    The test runner provides two means for marking bad test cases.

    First, you can pass a skip filter, which is a function that gets the test case passed in and returns true if a test should be completely skipped. It is most useful for filtering out tests that are not supposed to pass, for example because they test features that are not supposed to be implemented.

    Second, there is a whitelist, which is a list of test ids that don't yield the expected result. It should be used for tests that are supposed to succeed eventually.

    This is a simple example for running the tests against acorn:

    const run = require("test262-parser-runner")
    const parse = require("acorn").parse
     
    run(
      (content, {sourceType}) => parse(content, { sourceType, ecmaVersion: 9 }),
      {
        skip: test => false, // Default is to skip no test
        whitelist: [], // Default is to whitelist no test
        testsDirectory: "/path/to/test262" // Default is to use the bundled version
      }
    )
