Persisting state to the module Global Map Instead of making state >> state relative to its state (Make them functional) the entire object just depends on the input. remove global variables functional testings (Knows what's passed) make them ..

.toBeTruthy()​ Use .toBeTruthy when you don't care what a value is and you want to ensure a value is true in a boolean context. For example, let's say you have some application code that looks like: drinkSomeLaCroix(); if (thirstInfo()) { drinkMoreLaCroix(); } You may not care what thirstInfo returns, specifically - it might return true or a complex object, and your code would still work. So if ..

const getMedia = async (mediaId) => (await makeRequest({ url: `${MEDIA_BASE_URL}/admin/media/${mediaId}`, method: 'GET' })).data If this is the function that is making the request through the Axios, we can make it with some curry function and Axios innate data of config to make it and return it with Promise.resolve. const createMockImplementation = ({ contentId, mediaId }) => (config = {}) => { ..

Reset/Clear with beforeEach/beforeAll and clearAllMocks/resetAllMocks Assuming we have a global stub or spy that is potentially called mutliple times throughout our tests. const mockFn = jest.fn(); function fnUnderTest(args1) { mockFn(args1); } test('Testing once', () => { fnUnderTest('first-call'); expect(mockFn).toHaveBeenCalledWith('first-call'); expect(mockFn).toHaveBeenCalledTimes(1); }); t..

Mock Functions Mock functions allow you to test the links between code by erasing the actual implementation of a function, capturing calls to the function (and the parameters passed in those calls), capturing instances of constructor functions when instantiated with new, and allowing test-time configuration of return values. There are two ways to mock functions: Either by creating a mock functio..

Complexity means how difficult it is Integrating new EC2 Instance to broadcast stream >> Very Good (Automatically record it for us) Moving to a new framework of recording AWS EC2 Instance Some of the functions Tests are required. For the End to End test, we can call from the clouds Tests are required. For the local tests, we don't want to make any connection to the cloud (Change the cloud) Integ..

Jest worker encountered 4 child process exceptions, exceeding retry limit If you see this kind of message in your Console, it means that it has to be done with Async and await.
