ISO/IEC and Ecma International ratify “ES5.1”, the latest ECMAScript specification of Ecma International
Members of Ecma International work together to create official ECMAScript test suite
ISO, the International Organization for Standardization, IEC, the International Electrotechnical Commission and Ecma International have ratified ECMA-262 edition 5.1, signifying its recognition as an International Standard. This will facilitate its adoption by government organizations around the world, or its inclusion in public procurement requirements.
Release of the identical ECMA-262 edition 5.1 completes nearly a decade of work by Ecma Technical Committee 39 to ensure consistency in scripting across web browsers, and to enable the existence of interoperable web applications. The new ECMA-262 edition 5.1 is a minimal but needed update of edition 5, approved in December 2009 by the Ecma General Assembly. With additional editorial corrections and bug fixing it makes the implementation of the latest ECMA-262 edition easier and allows better interoperability among web applications. It is identical to ISO/ IEC 16262 edition 3.
For the first time, Ecma will publish a standardized test suite for the latest version of ECMA-262 edition 5.1, known as Test262. Via this suite, developers will be able to test how closely implementations of ECMAScript follow the specifications in ECMA-262 edition 5.1. The test suite will be published as an Ecma Technical Report and will be made available to developers via the normal Ecma distribution channels and http://test262.ecmascript.org/. The test suite will be released in increments with the first version planned for December 2011 and updates provided later.
The test suite has been created by the Ecma Technical Committee 39, with committee members including Mozilla, Microsoft, Google and many others helping to make the suite a resource that helps developers provide fine-tuned feedback on support for the standard.
Over 10,000 tests cover the specification today. Test suites are an integral part of the process needed to create interoperable cross-platforms standards.
