Test262 maintains most tests for the FunctionPrototype intrinsic within
the `test/built-ins/Function/prototype/` directory. Two tests are
defined within the otherwise-empty `test/built-ins/intrinsics/`
directory; relocate them to the canonical directory for consistency and
discoverability.
Some tests specifically concern the application of the `use strict`
directive as it appears in JavaScript source code. These tests should
*not* be run with the `onlyStrict` flag because relying on the test
runner to enable strict mode makes the semantics of the source code
irrelevant. Update these tests to use the `noStrict` flag.
Other tests concern language semantics that are only valid in strict
mode, but the mechanism for enabling strictness is inconseqential.
Update these tests to use the `onlyStrict` flag and remove any redundant
`use strict` directive prologues contained within.
Still other tests are valid both within and outside of strict mode.
In keeping with the majority of other tests, do not specify any
restrictions on the environments in which these tests may be run.
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
