who got tired of bad practice tests.
TestHoop is a free practice-exam platform for developer certifications. It started with Java 21, runs out of Pune, and is built by us — founder-led, and growing.

FOUNDERMost free practice tests floating around the web are years out of date, and half the answers are wrong. The paid alternatives charge $50+ per pack — on top of the exam voucher itself.
TestHoop is what we wished existed when preparing for our first certification: practice mocks that match the real exam format, kept current, with clear explanations — and free to take.
Today, questions are AI-generated against the current exam objectives and reviewed before publishing. As the catalog grows beyond the first pack, we'll bring in developers to author and review packs in their own domains. Nobody pays anything, ever.

Why TestHoop exists
01 · FREE DUMPS
Free dumps are wrong.
The practice PDFs floating around the web were written years ago. Half the answers are wrong and they don't reflect what's actually on the current exam blueprints.
02 · PAYWALLS
Paid platforms gate everything.
$49 for one pack. $295 for the actual exam voucher. Finding out whether you're ready shouldn't cost as much as the exam itself.
03 · TESTHOOP
Free, current, honest.
Real exam format, generated from the current exam objectives and reviewed before publishing. Every question has an explanation. Practice any pack without an account — sign in for timed mocks and saved progress.
