Mike Pennisi a6834093aa Improve coverage by invoking functions as intended 
Some tests which include function declarations designed to verify
behavior do not reference those functions. Insert the references
necessary for those functions to serve their intended purpose.

Mike Pennisi d9ddf80479 Revert "Merge pull request #3219 from tc39/rwaldron/migrate-comparearray" 
This reverts commit b690cb67be, reversing
changes made to 50dd431dff. This is
necessary because the reverted changeset reduced coverage by an unknown
extent.

rwaldron 4847d9db5a chore: update test/**/*.js to use assert.compareArray wherever applicable 2021-09-24 12:58:15 -04:00

Add test for freezing of module namespace object (#3213) 
Attempting to freeze the module namespace exotic object should not affect the `writable`-ity of the properties as that exercises the same `DefineOwnProperty` operation according to [`SetIntegrityLevel`](https://tc39.es/ecma262/#sec-setintegritylevel).

@erights discovered a [bug in v8](https://bugs.chromium.org/p/v8/issues/detail?id=12240) where, while the `Object.freeze` operation throws, it actually makes exported properties non-writable one by one.

At the request of @syg, I'm contributing a test against this behavior. The bug in v8 actually leads to a breakage of the objects invariants, however I'm not testing for that here as the root cause is the illegal freezing of the export.

Mike Pennisi 650e7add4a Improve coverage for ops involving negative zero 
Prior to this commit, the modified tests used the strict equality
operator to compare computed values with negative zero. Due to the
semantics of that operator, these tests would spuriously pass if the
value under test was in fact positive zero.

Update the tests to be more precise by instead asserting equality with
the `assert.sameValue` utility method (since that method correctly
distinguishes between negative zero and positive zero).
 2021-09-16 16:35:41 -04:00
Mike Pennisi 93ecde9f3a Correct typo to improve coverage 
Prior to this commit, the modified test included two different
expressions in positions that were meant to describe the same
expression. This meant that the value of the intended expression was
only partially verified.

Correct the test to fully verify the value of the expression.

Mike Pennisi 3b06fd012a Update test for deletion of SuperProperty 
The following proposed change modifies the semantics this test was
originally written to verify:

Normative: Allow null or undefined in Reference Records

Timothy Gu 6319cb1e2a Add more static class property ordering tests 
Since https://github.com/tc39/ecma262/pull/1490, the "length" and "name"
properties of a class are defined before any static methods. This is
tested by #2057, in test/language/computed-property-names of all places.

At the same time, static methods with "name" as the name would overwrite
the original property, but retain the original property enumeration
order. This was not previously tested. In fact, the overwriting behavior
was not tested at all for the "length" property.

This commit mends both holes in test coverage.

Mike Pennisi 9b4ca4371b Add tests for change in Reference Records 
These tests support the following normative change

"Normative: Allow null or undefined in Reference Records"
https://github.com/tc39/ecma262/pull/2267

The tests concerning the `delete` operator increase coverage to verify
behavior which, though related, is not altered by the normative change.
These tests are intended to guard against regressions as engines
implement the new semantics.

Mike Pennisi 9b622bf093 Remove or relocate misleading tests 
These tests were designed to test the built-in "Promise.race Resolve
Element function," but ECMA262 does not describe such a function.

Contrary to the test's description, the function under test is created
by the InstantiateArrowFunctionExpression abstract operation. The
following tests verify most of the details directly (only the function
object's extensibility was not already tested by the existing tests):

- test/language/expressions/arrow-function/name.js
- test/language/expressions/arrow-function/throw-new.js
- test/language/expressions/arrow-function/prototype-rules.js

The definition of the built-in resolving functions is closely related,
but Test262 already includes tests for the corresponding concerns:

- test/built-ins/Promise/resolve-function-extensible.js
- test/built-ins/Promise/resolve-function-name.js
- test/built-ins/Promise/resolve-function-nonconstructor.js
- test/built-ins/Promise/resolve-function-prototype.js

Remove the tests and introduce one additional test to preserve coverage
while improving discoverability.

Fix typo in private getter/setter tests (#2971) 
Several tests for getters and setters claim to check for an early
SyntaxError regarding mixing static and non-static propeties with the
same name. However, the tests trigger another issue: the getters have no
method body; they're missing curlies.

Fix the tests to test only the intended SyntaxError, not unrelated
SyntaxError-s.
