Sputnik (JavaScript conformance test)
Conformity test for JavaScript implementations
Sputnik was a JavaScript conformance test suite. The purpose of the test suite was to determine how well a JavaScript implementation adheres to the ECMA-262 specification, 5th edition, looking only at those features that were also present in the 3rd edition.[1] It contained over 5000 tests that touched all aspects of the JavaScript language.[1][2]
The test was created in Russia for testing the conformance of the V8 JavaScript engine used in Google Chrome.[1]
As part of phasing out Google Labs, Google has shut down Sputnik. All current Sputnik tests have been incorporated into ECMA's Test262 test suite.
