As the platform grew, Stellic needed tests that stayed stable even as the app changed — existing tools couldn't keep up.
Constant manual intervention and maintenance pulled engineering time away from shipping, slowing down release cycles.
Head of Engineering Jeffrey Wescott was specifically looking for AI to generate and auto-heal E2E tests, not another tool requiring babysitting.

About
Stellic
Stellic, a rapidly growing company specializing in academic planning software for higher education institutions, was facing challenges in maintaining reliable end-to-end (E2E) testing as their platform scaled. With over 80 employees and a growing customer base, they needed a solution that could not only automate E2E testing but also self-heal those tests as the application evolved.
the problem
Scaling a platform meant scaling testing pain
the Solution
AI testing that heals itself
Checksum uses AI to generate and self-heal end-to-end tests as your application evolves. Instead of manually writing and maintaining tests, Checksum's AI learns your app's flows, builds coverage automatically, and adapts when the UI changes — so your test suite stays accurate without engineer intervention.
Self-healing tests
When your UI evolves, Checksum automatically repairs affected tests,beyond just selectors, repairing underlying test logic when flows themselves change.
Auto-generation
Tests are generated automatically using proprietary AI, saving months of development time writing and maintaining tests.
Continuous by design
Checksum plugs directly into CI, running on every commit, every PR, and every deploy, so quality is baked into the workflow, not bolted on at the end.
the Results
E2e testing as a service, not just a tool
Less manual testing
More coverage on critical user journeys without increasing developer workload.
Broader coverage, same team size
Broader coverage, same team size
A partner, not just a tool
Faster releases with higher confidence, backed by a partner available when testing issues arise.
Checksum provides more than just AI-driven testing; they provide peace of mind. We no longer worry about broken tests or lengthy testing cycles. Instead, we can focus on scaling our platform and delivering value to our customers.
