About Faultline
Practice that grades itself.
Faultline exists for people who learn testing by testing. Read a brief, explore a realistic product, write the defect you would actually file, and get an objective score.
Why it exists
Testing is a skill you practise.
Reading about exploratory testing is not the same as doing it. Faultline gives you a product to poke at, a timebox to work inside, and feedback that explains the gap between a vague report and a useful one.
Deterministic feedback
The same report against the same answer key produces the same result. You can see exactly which fields matched and which did not.
Realistic surfaces
The sandboxes are working products with catalogue, banking, crypto, and trading journeys, not a multiple-choice quiz.
Privacy by default
The first release is guest-only. No account, no saved profile, and no analytics; guest attempts are deleted after grading.

What this is not
Not a certificate. Not a hiring test.
A Faultline score reflects how closely your reports match one hidden answer key. It is practice feedback, not a professional certification, a proctored exam, or a guarantee of job readiness.
