This blog post gives detailed insights into the most prevalent JavaScript E2E (end-to-end) testing frameworks. We break down our article into two main sections:

  1. Our experience - we tried six different frameworks by writing the same test case on the same web application and provided detailed pros/cons of working with those technologies. All the code examples are available here.
  2. Deep dive - to help you decide the best framework for your project, we pulled together many different data sources - e.g., the state of JS survey, social networks, GitHub, etc. We evaluate each framework across four categories: feature set, adoption & popularity, DX (developer experience), and maintenance.

A genuine Chrome browser power user can only reach maximum efficiency using shortcuts. Shortcuts bridge the gap over repetitive tasks that might not be individually super time-consuming. Still, they do add up and crawl up your productivity with time.

If you're getting into JavaScript and frontend development, you've probably come across many use cases where you'll need to fetch data from a remote service endpoint. Depending on the type of application you're working on, this data can come in many different shapes. For single-page applications, it's common to handle remote data in the JSON format and fetch it through HTTP requests. In this article, we want to guide you through some common patterns when handling such requests and share other tips we think are helpful.

Some time back, we've received feedback from a user stating that they could use our browser extension in mobile using the Yandex browser and gave some feedback about usability. We don't develop for mobile, but when we found out it was possible, we improved our import/export flow to allow users to quickly load in a JSON file with many rules and operate with the app while mocking requests with tweak. Let's look at how to achieve it.

Errors handling is part of our work as developers. You can try to ignore them at first, but to offer a good user experience, you don't want your website breaking just because one of the API endpoints decided to give up on you. These days we try to find clever workarounds to run our applications with a graceful degradation strategy. We build software to work in an optimal environment while providing certain fallbacks not to break the experience entirely when there's some disturbance in the system (e.g., lousy network condition, CPU lag, etc.).

In this article, we will understand how to maximize productivity when tackling HTTP requests error handling from a front-end development perspective.

In our "Complete Guide to Test Chrome Extensions with Puppeteer", we've covered all you need to know to get you up to speed on setting up end-to-end testing for a chrome extension. The fact is that many elements of the article can be brought to traditional front-end applications.

To truly deliver to you the complete knowledge we've acquired, we've decided to write this tiny, complementary blog post, where we'll cover ad-hoc topics, let's call it tips & tricks, to help you work with Puppeteer.
