const sinon = require('sinon'); // Require Sinon // Set up a test function to be called const testFunction = sinon.spy(); // Call the test function testFunction(); // Use assert.called to verify that the function was called sinon.assert.called(testFunction);
const sinon = require('sinon'); describe('Sample Test', () => { it('should call the function', () => { const testFunction = sinon.spy(); // Setup test function as a spy // Call the function within the test testFunction(); // Use assert.called to verify that the function was called sinon.assert.called(testFunction); }); });In these examples, we see that the 'sinon' package is used, indicating that the sinon library is being used for testing. Overall, Sinon provides a robust library of methods for testing complex Javascript applications.
