Test of spec language from 15.4.4.4,
5.b.iii.3.b states 'Call the [[DefineOwnProeprty]] internal method of A'
which means that the result of Array.prototype.concat
should return `true` from `hasOwnProperty` for every property
created by `concat`, up to `length`

Set length to 3.
a[0] is set to 0 on a
a[1] is unset
a[2] is set to 2 via a prototype of a

add assertions for values of b[0], b[1], b[2]
add assertions for b.hasOwnProperty('2')

Check with Array.prototype and Object.prototype, separate tests

fix typo in assertion message

test was correct, but assertion message was incorrect

Remove negative flag from test bed. Replace with specific errors. Other misc. fixes.

add "description" header back

remove now-unused includes

remove needless include

Correct test assertion (Fixes issue#61)

Correct Array.prototype.fill tests (Fixes #63)

Move tests to Math.clz32 (Fixes #41)

Number.prototype.clz() was renamed to Math.clz32(). Also removed superfluous 'spec' entry in test descriptor.

The expected results weren't correct.

Changed Number.isNaN_Boolean.js, String.prototype.endsWith_Fail.js and String.prototype.endsWith_Fail_2.js to test for the correct result. Also removed implicit coercion in a couple of other test files.

harness: remove unused code

sta.js:
slight change to Test262Error() semantics; message property now always set (default "")
make $ERROR a var
set $ERROR to function $ERROR so it can be overridden if needed
remove 2009 copyright in favor of 2012 copyright
REVERTED: remove never-used fn testFailed
testFailed actually used by $FAIL
remove obsolete fn $INCLUDE

ed.js:
remove commented-out obsolete code

test262.py:
remove always-included harness file that provides no functions used by any extant test
add comment line to nonstrict

cth.js: define `print` for node, cscript

use cth (console test harness) to define functions
for console runner.  V8, Spidermonkey (js) and JavaScriptCore (jsc)
provide a function `print`.  Provide a default `print` for node
and cscript

set print_handle to 'print' by default (can still override)
for cscript: wrap tests in try/catch so we get syntax errors

es6/Math: use Number.isNaN

CONTRIBUTING: more notes on test writing

Minor fixes: typos, formatting, verb tense&agreement
Add example of short-list `includes: []` and long-list `includes: \n - \n -`

use number.isNaN to test for NaN
pointed out by @anba in #60

Add section on test environment
Add section on custom helpers
describe YAML frontmatter
Fix minor formatting errors
document $INCLUDE as obsolete
Change documentation of negative error
Move test environment and custom helpers down
indent copyright and frontmatter sections
better description of the async calls between a promise
and the functions in its `.then`
Correct Early Error example: don't throw a string

CONSOLE-RUNNER: split runner doc into new file
add troubleshooting section

Normalize testcase format

parseTestRecord: add support for YAML frontmatter
parseTestRecord: initial unit test for test record parser
parseTestRecord: refactor for testing

factor old parsing; add YAML parsing

runner: support "includes" from YAML frontmatter

support frontmatter "includes" in python runner
use test.includes if present instead of scanning test code with regex

harness: factor individual functions out into files

tools: handle YAML errors

tolerate missing keys in dictionary (flags, includes)
report filename when empty frontmatter block
new option --list-includes to test262.py

harness: factor helper functions into separate files

sth: remove extra close-paren (syntax error)

test_common: TDD; failing parse of YAML

common: use parseTestRecord (YAML-aware)

This commit normalizes the test case format used across test262. It applies the following transformations:

* Convert to YAML for frontmatter
* Remove of trailing whitespace
* Replace /r/n with /n except in chapters 6 and 7.
* Copyright header always uses // comments
* new includes attribute replaces $INCLUDE
* No implicit assumptions about test environment other than $ERROR. Everything else appears in the include array. This includes "runTestCase" which is now included in a substantial number of tests.

Delete `Number.toInteger` test

`Number.toInteger` was removed from the ES6 draft. Fixes #62.

CONTRIBUTING: add notes on async

add a table showing which print handle to use when
running async tests through test262.py runner

@anba contributed information about async tests in
SpiderMonkey and JavaScriptCore

sth: correct syntax error in new fn isAsyncTest

test262.py: only include helper scripts when needed

CONTRIBUTING: document test262.py, async tests

add a section on requirements for using console test runner test262.py

add a section on asynchronous tests

add subsection to authoring guidelines with suggestion for test names

test262.py: only supply async helper scripts when test is async
sth.js: factor out function isAsyncTest()
timer.js: improve workaround for async tests when Promise is defined but setTimeout is noot

timer.js emulates setTimeout using Promise by doing a busy loop that checks
if `timeout` milliseconds have elapsed.  Modified check to (timeLeft > 0) instead
of (!timeLeft) to prevent infinite loop when check does not happen to run
at precise millisecond timeout expires.

Because test262.py did not support the $INCLUDE directive, some helper
scripts were added to every test -- notably testIntl, timer, and donePrintHandle
Now that $INCLUDE is supported, these can be dropped, speeding overall test run time

* hankyates/array-fill-tests:
  Adding Array.prototype#fill tests

Propagate error code when test cases are failed

Initial promise tests

packager: make packager runnable

packager.py cannot run due to syntax errors in a few script files

packagerConfig: use git instead of hg
test262: use pop instead of delete to avoid throw if property missing
S22.1.2.1_T*: fix docString header comment: s/b /**
S22.1.2.1_T3: fix docString header comment: s/b /**, fix end of docstring * / => */

doneprintHandle.js: make $DONE accept any falsy argument as meaning 'pass'
PromiseHelper.js: checkSequence: new helper fn for async tests
.gitignore: port .hgignore to .gitignore syntax
test262.py: support $INCLUDE directive in python test runner

S25.4.4.1*: tests to cover Section 25.4.4.1, Promise.all( iterable )
A1.1: Promise.all is callable
A1.2: Promise.all expects 1 argument
A2.1: Promise.all([]) is a Promise
A2.2: Promise.all([]) is resolved immediately
A2.3: Promise.all([]) is resolved with a new empty array
A3.1: Promise.all expects an iterable argument
