Some tests involving the directive prologue are invalidated by source
text transformations that insert executable code in the beginning of the
script. Implement a `raw` flag that allows these tests to opt-out of
this transformation. Update the relevant tests to use this flag (and
remove references to globals only available when code is injected).
Update the Python runner accordingly:
- Do not run tests marked as "raw" in strict mode
- Reject invalid test configurations
Update the browser runner accordingly:
- Do not modify the script body of tests marked as "raw"
Unlike the console runner, the browser runner does not modify the
strictness of tests prior to running them. Regardless of a given test's
metadata, it runs every test exactly once, and it never enables strict
mode. This means that tests intended to function in strict mode must
declare the "use strict"; directive prologue in addition to the
`onlyStrict` flag.
For any test that specifies the `onlyStrict` metadata flag, transform
the source code by injecting a "use strict" directive prologue prior to
running the test.
- Remove trailing white space
- Streamline documentation of test tags
- Do not reference obsolete tags
- Document `features` frontmatter tag
- Document `es6id` frontmatter tag
- Omit unnecessary detail about test262 website generation. This is not
directly useful to potential test contributors. Implementation details
like these can be taken for granted by that audience.
- Remove documentation on YAML syntax. Details on YAML may be helpful
for some new contributors, but this document should not attempt to
cover the topic (especially not from the description of a specific
frontmatter entry). Replace with a link to a more comprehensive source
as this will be more generally useful to those who need it (and less
obtrusive for those who do not).
- Consolidate information on test helpers
- Document `assert` helpers
- Update instructions for asserting errors. Since the introduction of
`assert.throws` in gh-22, the preferred means of expressing
expectations regarding errors has changed. Update the CONTRIBUTING.md
file to reflect the latest approach. Explain purpose of `throw
NotEarlyError;` in example test.
- Re-order information on file names. The inconsistency in the project's
file names should not go unmentioned, but neither should it not
preceed instructions for the accepted approach to namine tests.
- More clearly document required frontmatter tags. Explicitly list
`description` as a required frontmatter tag, implicitly identifying
all other tags as optional.
