* Express JSON syntax tests with multiple assertions When written with a single assertion, this test verifies only that "one or more" of the Unicode points produces a SyntaxError. Re-factor the test so that parsing behavior for each code point can be tested in isolation. * Re-introduce assertion ECMAScript edition 2016 relies on the Unicode standard at version 8.0.0. As part of a larger effort to update Test262 accordingly, the assertion for the SyntaxError resulting from the use of the Mongolian Vowel Separator (U+180E) was removed. However, ECMA-401 (The JSON Data Interchange Format) continues to describe "insignificant whitespace" as follows: > Insignificant whitespace is allowed before or after any token. > The whitespace characters are: character tabulation (U+0009), > line feed (U+000A), carriage return (U+000D), and space > (U+0020) And because ECMA262 specifies step 2 of the `JSON.parse` algorithm as follows: > 2. Parse JText interpreted as UTF-16 encoded Unicode points (6.1.4) as > a JSON text as specified in ECMA-404. Throw a SyntaxError exception > if JText is not a valid JSON text as defined in that specification. ...the use of U+180E between JSON tokens should continue to produce a SyntaxError, regardless of ECMA262's updated Unicode standard. * fixup! Express JSON syntax tests with multiple assertions
Test262 is the official ECMAScript (ECMA-262) conformance suite.
Test262 tests conformance to the continually maintained draft future ECMAScript standard found at http://tc39.github.io/ecma262/ , together with any Stage 3 or later TC39 proposals. It is maintained by Tom Care (@tcare) with significant contributions from many in the ECMAScript community.
