const assert = require('@ciscospark/test-helper-chai'); const obj1 = { name: 'John', age: 25 }; const obj2 = { name: 'John', age: 25 }; const arr1 = [1, 2, 3]; const arr2 = [1, 2, 3]; // Testing object equality assert.deepEqual(obj1, obj2); // succeeds // Testing array equality assert.deepEqual(arr1, arr2); // succeedsIn the above example, `assert.deepEqual` is used to test the equality of two objects and two arrays. If the objects or arrays are equal, the tests will succeed. The package library for `@ciscospark/test-helper-chai` is Chai, which is a popular assertion library for JavaScript. It provides a wide range of assertion methods and integrates well with test runners like Mocha and Jasmine.
