Dev Genius·4yHow to write maintainable JavaScript code in 2023 — Web or Node.js
Using TypeScript everywhere is best suited for JS developers with at least medium experience. Don’t be scared of TypeScript. Use prototypes and/or MVPs before implementing complex features. Use ESLint and Prettier together and you can focus on what your code does. If you use prettier, it will join multi-line breaks.
Medium·4y6 Best Practices for Software Delivery
The Testing Pyramid is a great starting point, and the Testing Pyramid to Fail Fast and Reduce Risk. The longer you leave feedback, the most costly it will become, you start having to interrupt people from other work, and after weeks/months pass by, it’s more likely that people and knowledge will leave.
ITNEXT·4yFront-end Testing Principles
For the Front-End we need to focus on only two targets for our tests: the end-user who interacts with your component in the browser and the developer who renders and uses your component. Writing your tests in isolation will guide us to a better way to write your tests to improve their reliability, simplify the code, and increase confidence.
Syncfusion·4yJavaScript API Mocking Techniques
API Mocking Mocking is a client-side mocking framework that mocks the API in the browser by using the Pretender library. It has many built-in tools: serializer, route handlers, database, models, fixtures, and factories. It enables emulating dynamic behavior between the front end and back end, rather than mocking the same response over and over again by hitting an endpoint.
Medium·4yHow we reduced our annual server costs by 80% — from $1M to $200k — by moving away from AWS
Prerender saved $800k by removing their reliance on AWS and building in-house infrastructure Combined with AWS, we had already cut our expenses by 22%. The testing phase was crucial to make sure the following processes would run smoothly. After testing whether Prerender pages could be cached in both S3 and minio, we slowly diverted traffic away from AWS S 3 and towards minio.

This Dot·4yGitHub Actions for Serverless Framework Deployments
Serverless Framework does all its configuration via a serverless.yml file. However, the framework officially supports alternative formats including.json,.js, and.ts. We decided to move all of our CI/CD to GitHub Actions. We had to make the following changes to our actions and configuration to get everything 100% working: serverless to get all of the serverless service. The app and org variables make it so it is required to have a valid dashboard login. This meant we couldn’t have a. serverless configuration.
Auth0·4yTesting React Applications with Jest
MockingJest allows you to mock objects in your test files. You can turn on automatic mocking with automock which will mock every component/object that the component is part of your project. For the first test, we'll write a simple test that ensures that Jest was set up correctly and that it can run a test successfully.
freeCodeCamp·4yWhat is Software Testing? A Beginner's Guide
Software testing is a complex topic and can be a bit difficult to understand. There are various methods you can use to test your code, and each testing method has different requirements. The version of the code/software for this phase of testing is released to a limited number of users for testing in a real-time scenario.
Helios·4yMicroservices testing: traditional solutions vs. modern strategies
Helios is a developer platform designed specifically for testing and troubleshooting microservices. By using Helios, developers can go back to relying on testing as an essential and trustworthy step for delivering production-ready code. Helios provides granular visibility into the entire microservices architecture and into each service. Their value is defined globally and can be easily replaced.
Community Picks·4yWhy Every Developer Should Employ Test Driven Development
Test-Driven Development (TDD) has gained popularity because it works to resolve the speed vs quality dilemma. Using TDD for software development is a more balanced approach emphasising three primary tasks: coding, testing, and designing. For each feature, I write 20-25 tests to cover all possible use Alternative option: a test framework abstracted.

Algolia Blog·4yHow to build a simulator for any feature — Part 1: Unit testing
Unit tests are just little pieces of code that verify that things are functioning as they should. It’s not deterministic (that is, the function doesn’t always return the same output for a given input, and it contains a few side effects that reach outside of the scope of the function. How can we fix this?

A practical tutorial about end-to-end testing with Golang Unit tests form a crucial part of modern software testing. A case study shows how these were added to an open-source project so that you can adapt the approach and techniques for your own work. The perils of unit testing are a lack of context.

Design Thinking is a powerful paradigm that software testers and QA professionals can use to create more user-centric software. Design thinking can have a profound impact on the software development and testing teams in both agile and waterfall modes of development. In agile development, design thinking helps the team to focus on the user experience and the customer journey.
TestDriven.io·4yPytest for Beginners
Pytest for Beginners Automated testing is an essential part of your development process. Well-written tests decrease the possibility of something breaking in a production environment. Tests also help you cover marginal cases and make refactoring easier. In our example app, pytest found 8 tests, and they all passed. At bottom of message, you can see how many tests passed/failed. Failing Test Your test won't always pass on the first try. In our own app, you could see how much tests were found. For more information, click here.

Curiosum·4yTesting React Applications
React Testing Library is a handy utility that adds APIs for working with React components. Next.js doesn't come with them out-of-the-box yarn add. It runs your testing scenarios inside a browser, which means that you can easily test your application as a whole. Cypress tests require having your development server running in the background, thankfully package named start-server-and-test does it automatically. Cypress and Playwright offer very similar functionalities.
