Compatibility

ES5.1

Sinon v7.1.1 is written as ES5.1 and requires no transpiler or polyfills to run in the runtimes listed below.

Supported runtimes

v7.1.1 has been verified in these runtimes:

• Firefox 45
• Chrome 48
• Internet Explorer 11
• Edge 14
• Safari 9
• Node.js LTS versions

There should not be any issues with using Sinon v7.1.1 in newer versions of the same runtimes.

If you need to support very old runtimes that have incomplete support for ES5.1 you might get away with using loading es5-shim in your test environment.
