- 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.
Test case 10.4.2-3-c-2-s verifies that eval can't instantiate variables in the calling context. However, it does not verify that the variable isn't matched to the global context either. Added test case 10.4.2-3-c-3-s to check for this.
- Add missing ".prototype" lookup in Array.prototype tests (Follow-up of #280)
- Add noStrict flag in global/S10.2.3_A2.2_*.js (implicit this-binding is part of the test)
- Provide correct this-binding in function/13.2-*.js
- Add missing assert.throws in "set-iterator-close-after-add-failure.js"
As written, the test behavior and description do not match--the
`throw` invocation takes place while generator execution is paused
*within* the `finally` block (not following it).
Ensure that the test exercises the described behavior (and remove
extraneous invocation of method under test).

From the ES6 specification:
> ## PropertyDefinition : IdentifierReference
>
> 1. Let propName be StringValue of IdentifierReference.
> 2. Let exprValue be the result of evaluating IdentifierReference.
> 3. ReturnIfAbrupt(exprValue).
> 4. Let propValue be GetValue(exprValue).
> 5. ReturnIfAbrupt(propValue).
> 6. Assert: enumerable is true.
> 7. Return CreateDataPropertyOrThrow(object, propName, propValue).
The increment/decrement operator evaluates its operand expression once. When
the operand expression is a property accessor, RequireObjectCoercible
and ToPropertyKey are called on the property accessor in the correct order.
The assignment operator evaluates its operands from left to right. When
the left-hand side expression is a property accessor, RequireObjectCoercible
and ToPropertyKey are called on the property accessor before the right-hand
side expression is evaluated.
- 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.)
