The previous description of the 11.4.1-4.a-5 test case implied that an environment object could not be deleted while inside a with. However, the actual test was to test whether the variable declaration could be deleted. The description has been updated to better reflect this.
Test 11.4.1-4.a-5 states that it verifies that an environment object cannot be deleted. However, this was giving a false positive. It was actually testing where a "var" declaration on an environment object cannot be deleted (there are other tests for this). This test case fails on Chrome 43, Firefox 38 and Internet Explorer 11.
Test case 10.4.2-3-c-2-s verifies that eval can't instantiate variables in the calling context. However, it does not verify that the variable isn't matched to the global context either. Added test case 10.4.2-3-c-3-s to check for this.
- Add missing ".prototype" lookup in Array.prototype tests (Follow-up of #280)
- Add noStrict flag in global/S10.2.3_A2.2_*.js (implicit this-binding is part of the test)
- Provide correct this-binding in function/13.2-*.js
- Add missing assert.throws in "set-iterator-close-after-add-failure.js"
From the ES6 specification:
> ## PropertyDefinition : IdentifierReference
>
> 1. Let propName be StringValue of IdentifierReference.
> 2. Let exprValue be the result of evaluating IdentifierReference.
> 3. ReturnIfAbrupt(exprValue).
> 4. Let propValue be GetValue(exprValue).
> 5. ReturnIfAbrupt(propValue).
> 6. Assert: enumerable is true.
> 7. Return CreateDataPropertyOrThrow(object, propName, propValue).
The increment/decrement operator evaluates its operand expression once. When
the operand expression is a property accessor, RequireObjectCoercible
and ToPropertyKey are called on the property accessor in the correct order.
The assignment operator evaluates its operands from left to right. When
the left-hand side expression is a property accessor, RequireObjectCoercible
and ToPropertyKey are called on the property accessor before the right-hand
side expression is evaluated.
- Add missing "var" declarations and noStrict flags
- Add strict mode tests for:
- arguments-object/10.6-6-3 -> arguments-object/10.6-6-3-s
- arguments-object/10.6-6-4 -> arguments-object/10.6-6-4-s
- Remove try-finally clean-up code
- Add strict mode compatible tests for eval-code/S10.4.2_A1.1_T*
- No strict mode compatible files added for eval-code/S10.4.2_A1.2_T*, because it doesn't really make sense in this context.
- (S10.4.2_A1.1 and S10.4.2_A1.2 should probably be removed, because the tested behaviour is not required by the spec.)
- Split S8.5_A10, S8.5_A4 and S8.1_A3 into declaration (both modes) and assignment tests (non-strict only)
Part of issue #35.

- Duplicate properties are allowed in object literals: test/language/expressions/object/*.js
- RegExpBuiltinExec was changed to use ToLength(lastIndex): test/built-ins/RegExp/prototype/exec/S15.10.6.2_A5_T3.js
- Non-undefined flags arguments allowed in RegExp constructor call: test/built-ins/RegExp/*.js
- Array.prototype.push throws TypeError if new length exceeds Number.MAX_SAFE_INTEGER: test/built-ins/Array/prototype/push/S15.4.4.7_A2_T2.js
- .length property of bound functions is configurable: test/built-ins/Function/prototype/bind/15.3.4.5-15-2.js
- Array.prototype changed back to exotic Array object: test/built-ins/Array/prototype/*.js, test/built-ins/Array/isArray/15.4.3.2-0-5.js
- in-statement-position-label-statement.js is an Annex-B test (B.3.2 Labelled Function Declarations), moved to annexB directory
- identifier-let-allowed-as-lefthandside-expression-strict.js needs to check for a SyntaxError (ES6, 12.1.1)
- Remove sort() calls in test/built-ins/Object/getOwnPropertyNames/*.js
- Remove sort() calls in test/language/block-scope/syntax/for-in/acquire-properties-from-*.js
- verifyConfigurable() needs to called last in test/built-ins/Object/is/length.js
- All productions within ClassBody are implicitly strict, update test/language/class/method-definition/yield-as-*.js accordingly
- Remove unnecessary noStrict flag in test/language/class/method-definition/yield-as-generator-method-binding-identifier.js
- Check own symbols are returned in property creation order from Object.getOwnPropertySymbols():
- test/language/computed-property-names/basics/symbol.js
- test/language/computed-property-names/class/method/symbol.js
- test/language/computed-property-names/class/static/method-symbol.js
- test/language/computed-property-names/object/method/symbol.js
- Fix copy-paste error in test/language/expressions/object/method-definition/yield-as-function-expression-binding-identifier.js
- Expand ambiguous assertion messages and assert execution paths more
finely.
- Improve variable names in `for..of` tests
While the object created by a GeneratorFunction may be considered an
"iterable", it is being used as an iterator in these tests. Naming the
variable according to the way it is used improves the readability of
the test body.
- Add 'features' attribute to test frontmatter
- Move tests
- Introduce additional `for..of` control flow tests
