As answered by people managing Project Euler and TestAcademy.dev.
TestAcademy.dev's answer:
TestAcademy does more than check if your automated test passes.
You write tests using Playwright, Cypress or Selenium and run them against a working application. Then TestAcademy checks your tests against versions of the application where bugs have been added on purpose.
You can see which bugs your tests caught and which ones they missed.
This helps you understand whether your tests actually check the right behaviour, not just whether they pass.
TestAcademy.dev's answer:
TestAcademy focuses on learning by doing.
You can write and run automated tests directly in your browser without installing anything.
The platform offers hands-on practice problems, Playwright, Cypress and Selenium lessons, QA interview questions, AI mock interviews and a free test code review tool.
You also get feedback on your code and can check whether your tests catch real problems in the practice applications.
You can start for free.
TestAcademy.dev's answer:
TestAcademy is built for people who want to learn or improve their QA automation skills.
This includes beginners, manual testers moving into automation, QA engineers learning Playwright, Cypress or Selenium, and professionals preparing for technical interviews.
It can also help QA leads and hiring teams review how candidates write tests and which bugs their tests detect.
TestAcademy.dev's answer:
The idea behind TestAcademy is simple: a passing automated test does not always mean the application has been tested properly.
A test might pass even when an important feature is broken.
TestAcademy focuses on solving this problem through hands-on practice. Instead of only teaching how to write tests, it gives learners a way to check whether their tests can catch bugs.
The goal is to help people develop practical QA automation skills they can use in real projects.
TestAcademy.dev's answer:
TestAcademy is built with Next.js, React, TypeScript and Tailwind CSS.
The platform also uses Auth.js for authentication, Upstash Redis for data storage, OpenAI for AI-powered features, Paddle for payments and Vercel for hosting.
For browser testing practice, TestAcademy supports Playwright, Cypress and Selenium.
