How does sinon.createSandbox work?

sinon.createSandbox creates a new Sinon sandbox object with methods to create and manage spies, stubs, and mocks, as well as restore them all at once. It is used to isolate tests and prevent any side effects from interfering with each other. The sandbox can be customized with options to add or remove behavior, and can be restored at the end of the test to clean up any changes made during the test.

const sinon = require("sinon");

// create a new sandbox
const sandbox = sinon.createSandbox();

// stub a method using the sandbox
const stub = sandbox.stub(obj, "method");

// restore the stub
sandbox.restore();

In this example, sinon.createSandbox() is used to create a new sandbox object that can be used to isolate and control the behavior of sinon stubs, spies, and mocks. The sandbox object can then be used to create a stub of a method on an object obj, and later restore the stubbed method using sandbox.restore().
