Unit Testing in Node.js and TypeScript: A Comprehensive Guide with Jest Integration
If you are using a mocking library, such as sinon, jest-mock, or ts-mockito, make sure that it is compatible with Jest. You may need to install additional packages or configure them in your configuration file. For example, to use sinon with Jest, you can install the sinon-jest package and add the following to your configuration file:
-
Express API Testing
Mocha is a test runner, Chai is an assertion library, Sinon is a mocking library, this normally the combination you would need to use if you choose mocha, but there are others.
-
Alternative to AWS Mock
Instead, use pure functions + dependency inject your stubs (e.g. parameter to function). Also note, no need for Sinon or some other test double library. JavaScript is so good nowadays to easily make objects/classes/functions or any combination thereof on the fly that are terse.

Unit testing: What to use, and how?
I've had some good experiences with Ava + Sinon. I've personally disliked Jest because it seemed to do some weird trickery in the background that prevented me from using ES modules.

Can AI help me write tests on legacy code?
๐ค You can use the Mocha testing framework with the Chai assertion library to write tests for your Express controller. You can also use the Sinon library to mock the database calls. This will allow you to test the controller without actually making a call to the database. You can also use the SuperTest library to make HTTP requests to the controller and test the response.

Need help writing a jest test that mocks an API call which will update state
You can use sinon js to create a mock version of your http library (axios) that responds with the data youโre expecting.

Unit testing with React and Cypress
Assertions are the checkpoints of our test block that confirm if an automated test has passed or failed. Cypress bundles the Chai, jQuery, and Sinon.JS libraries for assertions. They check the desired, expected application in which the test is running. A complete listing of assertions can be found in the documentation here.
-
When to use DI?
ES module is basically a "class" that you inject dependencies into through imports. And for tests you just use something like sinon to swap module dependencies for mocks.

How to test a function that uses moment to format a date ? usimg karma
You can use a tool like sinon to pass in your own function instead of the real moment library. From there you can write tests that ensure moment was invoked appropriately.

Express API Testing
Supertest is quite popular and easy to use test tool, you can do integration and E2E test as well, you just need to pass it the server instance or a string to make a request and assert over the response.
-
How can I test an Express application through a terminal?
If the latter, there are a bunch of different options for writing automated tests. One popular way is using Jest to run your tests. If you're trying to test the backend end-to-end flow, you could use Supertest to make requests and assert on the responses.

Ever hear of anyone doing headless functional testing with Jest?
I did something similar with a full stack Typescript project, using supertest and node-fetch. It was nice.

Jest testing custom middleware
This is why integration tests > unit tests. I really hate mocking and I never bother testing individual units that don't affect how users use my app and code. In your case, I'd just use something like supertest to test this functionality e2e.

Hi im having trouble building my api tests
Yes, but when every function handler is separate from the router, then you can use node-mocks-http to test each handler, to test the router is simpler to use supertest to write integration tests, for E2E tests I personally recommend [pactum](pactumjs.github.io/)

Patterns and Anti-patterns in Node.js
In a Node.js application, writing API tests is a good start. They provide more coverage than unit testing. You can use frameworks like Supertest, Jest, or any other library that provides a high-level abstraction for testing APIs.
