Ways to reduce execution time on automated tests
✅ Use API / libraries to quickly generate test data - Instead of creating test data via the UI, it is significantly faster via API or libraries. Plug-ins such as faker or running API's can be included in the test scripts before any UI functionality is performed.

How to Build a Webex Chatbot in Node.js
We also use the faker package (locked to version 5.5.3, since the latest version no longer works as expected). This library is often used for generating fake test data, but its API includes a set of calls for generating company buzz phrases. That’s what Buzz will use to generate the phrases we’re looking for.

What NPM Should Do Today to Stop a New Colors Attack Tomorrow
They supposedly took over the npm packages[0,1], not the github.com repos. npm is a system where you push archives as package versions, it doesn't do its own pull from a github repo or otherwise.

This week, if you tried to install Faker.js (a very popular library for creating mocks) you've noticed version was set on "6.6.6" and all code was gone with the text "What really happened with Aaron Swartz?".

Modern React testing, part 5: Playwright
We’re going to use Mock Service Worker (MSW) for mocking network requests in our integration tests and in the app during development.

Easier TypeScript API Testing with Vitest + MSW
However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

Creating mocks for testing react code
While mocks are effective, they require modifying the component's internal logic or mocking global functions like fetch. This can become cumbersome for complex components with numerous API interactions. Here's where MSW shines.

Storybook 8
> For those wondering what the use case is, you must not have tried it. It does take work to set up (with each version that's less), but it can be very nice to test in isolation esp in cases where a component is under a login, the 4th page of a 10 page form, etc. Also obviously if you're working on a component library that ships without an app, Storybook can be your development and/or demo app.
I have worked with storybook extensively over the past couple of years and my team is moving away from it in favour of MSW (https://mswjs.io).
For "4th page of a 10 page form" during the development there's hot reloading which is really stable nowadays and haven't failed me, although I understand that some setups are old and it might be easier to configure Storybook than good hot reloading.
I'm not entirely sure about the testing part of it and I'd be grateful if you could elaborate. I haven't felt the need for some special setup with SB because for unit tests, I can test a deeply nested component separately. For E2E tests, I usually test the whole form.
I agree on the component library part, this is probably the only use case where Storybook is 100% justified, but I'm unconvinced about the
Additionally, thank you to all our community launch partners across the frontend ecosystem for helping us bring Storybook 8 to the world!

How to Automatically Consume RESTful APIs in Your Frontend
With orval, we can also integrate the API client in our unit tests. Orval provides first class support for mocking through the (Mock Service Worker)[https://mswjs.io/] library, and it can automatically generate the MSW handlers for testing server.

Consider a hypothetical scenario where data from a list of companies within an ERP needs to be retrieved. As a personal recommendation, leverage tools like MSW for top-level mocks, which can significantly enhance the testing process.
