* Assert creation of 'arguments' object
Ensure that the 'arguments' object is created in cases where it is not
required by the body but is required by the parameters.
* Add tests for cases that disable "arguments" map
* Add tests for NewTarget override of bound function
* Add test for properties of exotic String objects
* Add tests for early errors in functions
* Improve tests for class accessors
Use the `propertyHelper.js` utility in order to functionally test the
property descriptors of class methods.
* Remove redundant tests
The semantics of an IdentifierReference as a PropertyDefinition within
an object initializer are exhaustively tested by the files in this
directory whose name match the pattern `prop-def-id-*.js`.
Delete the redundant tests in favor of the more descriptively-named and
more exhaustive alternatives.
* Rename tests
* Update test names to be more descriptive
* Add tests for property descriptors of accessors
* Add tests for runtime error during method dfn
* Add test for observable iteration
* Extend tests for class "name" inference
Ensure that when a class defines a static "name" method, that method
definition prevents the "name" inference behavior.
* Re-generate tests
Fixes gh-696
As pointed in gh-696, the ArrayBuffer ctor won't throw a RangeError when
invoked without arguments.
Instead of fixing the invalid assertion, this commit removes it as the
coverage for subclassing is already satisfied by the use of slice.
The global isNaN is not precise at all, and Number.isNaN is an ES6 feature that makes it preferrable to use assert's sameValue for NaN values, as it handles it internally using the comparison.
This test was intended to assert the semantics of the `for-in`
statement, but it was mistakenly authored to use a `for-of` statement.
Update the statement under test, and improve the testing methodology to
correctly assert the creation of distinct bindings.
Ensure that early errors restricting labelled function declarations
within WithStatement and IfStatement are honored. Rename existing tests
to match the specification's spelling.
A subtle aspect of the for-of iteration protocol concerns abrupt
completions that do *not* trigger iterator closing. Although this detail
is implicit in the current structure of the specification text, some
hosts may violate the protocol by closing the iterator because later
steps *do* specify that behavior.
The V8 engine is one such host--as of this writing, it incorrectly
closes the iterator when accessing the `value` property of the iterator
result produces an abrupt completion.
Add tests verifying that the iterator protocol is not violated in this
way for abrupt completions during the semantics of for-of evaluation.
Ensure that when HasBinding of an Object environment record returns an
abrupt completion, that same completion is returned to the runtime.
Update the meta-data of related tests for consistency with this new
test.
The latest revision of ECMA262 makes special provisions for classes
which extend the `null` value [1]. Update the relevant tests
accordingly.

Add tests that assert the management of the running execution context's
LexicalEnvironment and VariableEnvironment components, as created by the
following abstract operations:
- NewDeclarativeEnvironment
- NewObjectEnvironment
- NewFunctionEnvironment
Many tests require the use of non-strict direct eval, meaning they may
not be run in strict mode. This does not effect coverage because the
semantics in these cases are not observable from strict mode code.
Some situations require the creation of a binding, but this binding has
no relevance to the test itself. In these cases, use names consisting
solely of the underscore character (`_`).
Avoid the use of Block statements wherever possible, as these trigger
the creation of additional environments which may interfere with the
behavior under test.
This harness function is not necessary in the majority of cases in which
it is used. Remove its usage to simplify tests and decrease the amount
of domain-specific knowledge necessary to contribute to the test suite.
Persist the harness function itself for use by future tests for ES2015
modules (such a helper is necessary for tests that are interpreted as
module code).
The runtime semantics of this statement are host-defined and therefore
untestable, but the statement's affect on the formal grammar should be
consistent across all implementations.
