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.

Writing good documentation is a mission-critical aspect of building software these days. Whether you are writing something for yourself, for the Open Source community, or your company, it's essential to keep things documented for good reasons:

  • It makes developers more productive since they can rely on the docs to understand how to use your software.
  • It makes developing the software itself easier promoting knowledge sharing amongst developers.
