A conforming implementation of ECMAScript may provide additional types, values, objects, properties, and functions beyond those described in this specification. In particular, a conforming implementation of ECMAScript may provide properties not described in this specification, and values for those properties, for objects that are described in this specification.

The behavior under test is verified by another file in Test262:
test/language/expressions/compound-assignment/S11.13.2_A2.1_T3.3.js
That version is preferable because it does not depend on `eval` and
because it supports both strict and non-strict mode.
* Remove overly-permissive test
By asserting only the presence of an "own" property, this test can be
satisfied from both strict mode code and non-strict mode code.
The following test verifies the presence of the "own" property and the
associated descriptor's values in strict mode:
test/language/arguments-object/10.6-13-c-3-s.js
That subsumes the semantics verified by this test, making it
superfluous. Remove the test.
* Remove overly-permissive test
By asserting only the absence of a syntax error, this test can be
satisfied from both strict mode code and non-strict mode code.
The following test verifies the runtime behavior of accessing the
property in strict mode code:
test/language/arguments-object/10.6-13-c-1-s.js
That subsumes the semantics verified by this test, making it
superfluous. Remove the test.
* Remove duplicate test
The behavior under test is verified by another file in Test262:
test/built-ins/Math/prop-desc.js
That version is preferable because it follows the test suite's
convention for testing property descriptors and because it supports both
strict and non-strict mode.
* Remove duplicate test
The behavior under test is verified by two separate files:
test/language/statements/function/line-terminator-non-strict.js
test/language/statements/function/line-terminator-strict.js
These files differ only in their usage of the `noStrict`/`onlyStrict`
metadata. Because tests are intended to be interpreted in both modes by
default, these can be expressed with a single file that does not limit
the permissible modes.
Prior to this patch, the modified test would pass if no exception was
produced. Use the `assert.throws` utility function to concisely express
the expectation more completely.
Prior to the application of this patch, the modified test template
included an unintentional syntax error. This caused all generated tests
to spuriously satisfy the expectation for an error.
Correct the syntax in the test template and regenerate the tests,
ensuring that when engines report a syntax error, they are demonstrating
the behavior which the tests were designed to verify.
Previously, these tests were limited to strict mode. The syntactic
restriction under test also applied outside of strict mode even when
Annex B is observed, so configure the tests to also run outside of
strict mode.
Prior to this commit, the descriptors of the constructor properties of
the global object were verified inconsistently, many independent
assertions occured in the same file, and that file test was poorly
located.
Restructure the relevant tests to improve coverage, follow convention,
and promote discoverability.

Prior to this commit, the enumerability of the value properties of the
global object were only verified in strict mode, the assertions occured
in the same file, and that file test was poorly located.
Restructure the relevant tests to improve coverage, follow convention,
and promote discoverability.
The modified tests are equally valid in strict mode and outside of
strict mode. Remove the flag which limits their use to only one of these
two contexts. Rename tests using the legacy ES5-based naming scheme to
remove the pattern which designates strict mode.
The `$DETACHBUFFER` function is the preferred mechanism for detaching
array buffers.
Likewise, `verifyNotWritable` is the preferred mechanism for asserting
lack of writability.
The values defined by the referenced files are not used by these tests.
This makes their inclusion superfluous, which needlessly increases the
time to execute the tests and may confuse some readers.

Due to changing idempotenxy for dynamic import on failures these tests are no longer needed.
After tc39/ecma262#1645 idempotency is only required after completing normally.
