Most tutorials only check one thing: did your test pass. That is not the same as: would your test catch a real bug.
Here is a simple example. A test clicks "Add to cart" and checks that the cart badge exists. It never checks the number on the badge. If the badge shows the wrong count, the test still passes. That is a weak test, and it looks exactly like a good one on paper.
I have worked as a QA Automation Engineer for a few years now, most recently as the only QA engineer on a large enterprise platform. I have seen a lot of tests like this. They pass in CI, everyone feels safe, and then a real bug slips through anyway.
So I built TestAcademy.dev to fix that gap.
How it works
Every practice problem runs your test twice.
First, against the real app. Your test should pass here.
Second, against a version where I broke something on purpose, a real bug. If your test still passes here, it failed. It means your test would not have caught that bug in real life.
There are a few other checks too:
If your test only passes when it runs after another specific test, we tell you that.
If your test passes sometimes and fails other times, we tell you that too, and explain why.
None of this uses AI to guess if your test is good. It is all deterministic. Same test, same result, every time.
What is on the platform
Practice problems in Cypress, Playwright, and Selenium
A learning path for each framework, plus one shared path for concepts every tester needs
Interview practice questions by framework and level
Free to try, no account needed
Why I am posting this
I built this on my own, next to a full time job. I would rather hear what is confusing or missing now, from real people, than guess.
Try it at https://www.testacademy.dev/. The fastest way to see the point: solve one problem, then write a lazy version of the same test on purpose. Watch it get caught.
