While we're at it, use assert() instead of assert.sameValue() for brevity,
if we are not specifically testing that the return value of hasOwnProperty
is the value true or false; and add more informative assertion messages to
help with debugging.
In some cases, the Object.hasOwnProperty.call could be replaced with
verifyProperty(), if the property descriptor was also being verified at
the same time.
This fixes some tests that were faulty to begin with: a common mistake was
Object.hasOwnProperty(obj, prop) which is probably going to return false
when that's not what you want.
The only instances left of `Object.hasOwnProperty` are one regression test
in implementation-contributed which I can't tell if it was intentionally
needed to trigger the regression, and a few instances of
`Object.hasOwnProperty('prototype')` which would defeat the purpose to
convert into `Object.prototype.hasOwnProperty.call(Object, 'prototype')`
form.
Closes: #3524
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.
These tests are not helpful for their respective APIs being tested.
They don't add any coverage for the built-in apis and basically check
behaviors that might conflict with a implementation defined global.
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).
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.
- 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.)
- 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
- use negative: to check error types instead of
using `instanceof` in a catch() block
Selected commit logs follow:
manual conversion of accessorPropertyAttributesAreCorrect() test
- remove runTestCase
- remove wrapping testCase function
- unindent
- remove includes of runTestCase & accessor...
- add include of propertyHelper.js
- unpack final two args 'true, false' to explicit inline
tests of isEnumerable and isConfigurable
- unpack setter test into inline logic
- unpack getter test into inline logic
used script to replace includes: frontmatter
with propertyHelper.js ; manually added back
references to fnGlobalObject() where needed
additional helper functions
add helper functions for get and writable
duplicate runTestCase so can remove runTestCase.js from
includes of all tests in batch
use keyboard macros to simplify repetitive conversions
remove auto-save file accidentaly committed
minor changes, manually remove runTestCase from remaining files
lint etc. fixes
remove now-obsolete harness files
make strict/nonstrict variants
tests where behavior is different in strict/nonstrict
need two variants
- strict mode throws on assign to read-only element (no setter fn)
- strict mode separates named arguments from arguments[]
