The phase field must precede the type field for negative tests
to have a consistent style and be able to parse easier.
Related to the goal of https://github.com/tc39/test262/issues/1997
Added this check to the linting script and updated tests accordingly.
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.
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'
- Re-organize existing tests for identifiers
Name files according to their content (not their ES5 ID). Move tests
for IdentifierName and LabelIdentifier to more appropriate directories.
- Simplify and correct tests
Instead of asserting successful runtime evaluation using `eval`, rely
on the test runner's ability to detect syntax errors. Update the test
bodies to test the grammar referenced by their ES5 ID and
description--the IdentifierStart pattern.
- Use `negative` frontmatter to assert SyntaxErrors
- Remove redundant tests
- Use `assert.equal` helper function
- Add equivalent tests for literal unicode chars
- Add tests for variable-length unicode escape
