Early errors may result from parsing the source text of a test file, but
they may also result from parsing some other source text as referenced
through the ES2015 module syntax. The latter form of early error is not
necessarily detectable by ECMAScript parsers, however. Because of this,
the label "early" is not sufficiently precise for all Test262 consumers
to correctly interpret all tests.
Update the "phase" name of "early" to "parse" for all those negative
tests that describe errors resulting from parsing of the file's source
text directly. A forthcoming commit will update the remaining tests to
use a "phase" name that is more specific to module resolution.
Because expectations regarding error "phase" are now expressed via test
meta-data, the test runner may now enforce this requirement on negative
tests.
Remove the "NotEarlyError" from the project source. This reduces the
amount of domain knowledge required to author tests and lessens the
potential for inconsistencies between tests.
Authored via the following command:
$ find test -type f -print0 | \
xargs -0 sed \
-i 's/^\(\s*\)negative:\s*SyntaxError\s*$/\1negative:\n\1 phase: early\n\1 type: SyntaxError/g'
* Extend tests for class "name" inference
Ensure that when a class defines a static "name" method, that method
definition prevents the "name" inference behavior.
* Re-generate tests
This change set includes tests for most invocations of the
SetFunctionName abstract operation in the ES2015 specification.
Practical testing considerations preclude the introduction of tests for
certain invocations:
- The project is still vetting methods to sustainably test the semantics
of the Destructuring Binding pattern across all valid productions.
- 13.3.3.6 Runtime Semantics: IteratorBindingInitialization
- 13.3.3.7 Runtime Semantics: KeyedBindingInitialization
- Without a loader, there is no way to access a function object declared
in an ExportDeclaration, so `name` assignment cannot be tested in
these cases
- 14.1.19 Runtime Semantics: InstantiateFunctionObject
- 14.4.12 Runtime Semantics: InstantiateFunctionObject
- 14.5.15 Runtime Semantics: BindingClassDeclarationEvaluation
- 15.2.3.11 Runtime Semantics: Evaluation
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.
- 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
