In neglecting to assert the type of error thrown (or that any error was
thrown at all), these tests cannot fail. Refactor the tests to use the
`assert.throws` helper method, which takes these details into
consideration.
This function is equivalent to `$ERROR` (which is automatically included
in test environments). Remove the harness file that defines the
function, remove references to the file from test `includes` lists, and
update scripts to instead invoke the `$ERROR` function.
- Remove no longer needed noStrict flags.
- Change tests to use propertyHelper.js for strict mode compatibility.
- Add tests for return value of `delete` operator, e.g. `delete Array.prototype === false`.
- Add non-writable tests for global NaN property.
- Split some tests to run in strict mode.
- Change tests with global `var length` declaration to use a different variable name for browser environments.
- Merge duplicated tests symbol-data-property-configurable-non-strict and symbol-data-property-configurable-strict.
- Merge duplicated tests symbol-data-property-writable-non-strict and symbol-data-property-writable-strict.
- (And a small change in propertyHelper to reduce code duplication in function call.)
- 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
