Some popular JavaScript engines display violation of invariants about
property attributes for some non-standard but “web-reality” object
properties. Add tests against such violations
Closes#653Fixes#649
* Add tests for prototype realm inference
* Add tests for miscellaneous realm concerns
* Add tests for realm of spec-created Errors
In some cases, Error objects produced by the specification are
observable from ECMAScript code. Among these cases, some are further
differentiated in that they occur outside of any built-in function and
may be triggered through syntactic production directly. The current
realm record is commonly interpreted incorrectly under these
circumstances.
Add tests asserting that the expected realm record is used when
constructing such Error objects.
* Add tests for realm use in ArraySpeciesCreate
* Add tests for function realm retrieval
* Add tests for cross-realm behaviors of Symbols
* Add tests for GetValue and PutValue
* Add tests for realm of spec-created Arrays
In some cases, Arrays produced by CreateArrayFromList are observable
from ECMAScript code. Among these cases, two occur outside of any
built-in function and may be triggered through syntactic production
directly. The current realm record is commonly interpreted incorrectly
under these circumstances.
Add tests asserting that the expected realm record is used when
constructing arrays.

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 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).
- String case functions iterate over code points
- Has called before Get in Array.p.reverse
- Add test for web-compat Array.p.splice behaviour; Plus missing test for no arguments case
- ToObject no longer applied to this-value in Array.p.toLocaleString
- ToObject no longer applied to this-value in Object.p.toLocaleString
- Add tests for Object.p.propertyIsEnumerable and symbol property keys
- Add tests for Object.p.hasOwnProperty and symbol property keys
- Test property descriptor attributes of message property
- Tests for RegExp constructor checks
- Date constructor when called with date object
- TimeClip never returns negative zero
The `negative` frontmatter tag expresses an expectation for the behavior
of the test file as a whole. The `assert.throws` helper function offers
more fine-grained control over expectations because it may be applied to
specific statements and expressions. This makes it preferable in cases
where it may be used (i.e. when the test body does not describe a syntax
error or early error).
Re-implement assertions for errors to use the `assert.throws` helper
function wherever possible.
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.
The `$PRINT` helper function has no effect on test behavior. The
following tests use it to report assertion outcomes (and as a result
will fail silently):
- test/language/function-code/S10.2.1_A4_T2.js
- test/language/function-code/S10.2.1_A5.1_T1.js
- test/language/function-code/S10.2.1_A5.1_T2.js
- test/language/function-code/S10.2.1_A5.2_T1.js
Remove the function definition and all references within tests. Update
tests that use it as an error reporting mechanism to instead use an
appropriate `assert` helper function.
In neglecting to assert the type of error thrown (or that any error was
thrown at all), these tests cannot fail. Refactor the tests to use the
`assert.throws` helper method, which takes these details into
consideration.
This function is equivalent to `$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.)
- Add missing "var" declarations and noStrict flags
- Remove invalid noStrict flags
- ietestcenter tests need fixed, require updates to use propertyHelper.js
Part of issue #35.
- 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
These tests are derived from the following files within the Google V8 project:
test/mjsunit/harmony/array-fill.js
test/mjsunit/harmony/array-find.js
test/mjsunit/harmony/array-findindex.js
test/mjsunit/harmony/array-from.js
test/mjsunit/harmony/array-of.js
The expected values were already changed in a previous commit (@49abae4f5e6b38931d86dc9b9d34ae30d9ced2ca),
only the test descriptions still needed to be updated. (Fixes#138)
- this change hits all files that use
dataPropertyAttributesAreCorrect or
acccessorPropertyAttributesAreCorrect
Major changes:
- remove include of runTestCase.js,
dataPropertyAttributesAreCorrect.js and
acccessorPropertyAttributesAreCorrect.js
- add include of propertyHelper.js
- remove function testCase() and call to
function runTestCase()
- instead of collecting test state into booleans,
which are eventually returned from runTestCase,
test conditions and throw errors immediately
