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?
🤖 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.

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.

JavaScript Compare Dates: From Chaos to Clarity
Moment.js lets you do amazing things with dates and times in JavaScript. You can easily compare, change, and format them in different ways. For example, you can say things like "today is Monday" or "3 hours ago" or "12/31/2020". To start with Moment.js, you need to install it and import it into your JavaScript project. For example:

Adding "Created At" and "Last Updated" Dates to Jekyll
After hours of trying to figure out why Jekyll was still showing "Today" for a post I modified last week, I remembered that I am using the timeago filter from jekyll-timeago plugin. I was rendering the dates using {{ doc.last_modified_at | timeago }}. As you know, Jekyll is a static site generator, and it renders this as HTML at the time of build, and only then. This means any date rendered with timeago is hardcoded as is in the HTML and won't change until the next build. I switched all the dates to the "%-d %b %y" format for now. Might use moment.js in the future to get the timeago dates back.

👨🚀 Traversing Time with Intl.RelativeTimeFormat()
For the longest time working with dates in JavaScript was a huge pain. That’s why libraries such as moment.js or date-fns are so popular. A lot of times I’d reach for these libraries when working with relative time formatting, but since late last year we’ve had pretty great browser support for the RelativeTimeFormat() method. In my mind, relative dates are just more visually appealing, especially for working with dates internationally. Dates like "5 days ago" or "in 2 months" are far more intuitive for users than 12/12/2023, or 03/11/2027. Folks in the US will see that as March 11, 2027, whereas the rest of the world will see that as November 03, 2027. What a nightmare.

JS Date: The Timezone Tantrum
We could control the DST flip by setting the test's input time to the appropriate time of year (summer/winter). However we couldn't control the timezone. We had to adjust the expected data in the test 🤢 using the same library which the production code used (momentjs).
