Add tests that assert the management of the running execution context's LexicalEnvironment and VariableEnvironment components, as created by the following abstract operations: - NewDeclarativeEnvironment - NewObjectEnvironment - NewFunctionEnvironment Many tests require the use of non-strict direct eval, meaning they may not be run in strict mode. This does not effect coverage because the semantics in these cases are not observable from strict mode code. Some situations require the creation of a binding, but this binding has no relevance to the test itself. In these cases, use names consisting solely of the underscore character (`_`). Avoid the use of Block statements wherever possible, as these trigger the creation of additional environments which may interfere with the behavior under test.
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 Gorkem Yakin (@goyakin) with significant contributions from many in the ECMAScript community.
