Value identification and comparison functions
Documentation: http://sinonjs.github.io/samsam/
## Compatibility
Follows the same compatibility approach as the rest of the Sinon libraries: essentially the last 2 versions of evergreen browsers and the maintained runtimes of Node. See the [compatibility docs for the main Sinon project](https://github.com/sinonjs/sinon/blob/main/COMPATIBILITY.md) for detailed information.
## Testing
- Run `npm test` for the Node.js test suite.
- Run `npm run test-headless` for the browser-bundled `@mochify/cli` suite.
- In restricted environments, `npm run test-headless` may need unsandboxed access to launch Chrome through Puppeteer. If the browser fails to start before any specs run, retry it with normal system browser access.
