Case Study: Piece of Cake achieves 70% faster test creation and confident continuous deployments with mabl

Piece of Cake doubles down on DevOps by testing continuously to deploy with more confidence

Piece of Cake, the Japanese online media company behind note and cakes, struggled with no efficient automated browser testing to detect critical issues in staging before deployments, relying on slow manual checks. To address this, they trialed and adopted mabl, an AI-powered SaaS test automation solution.

With mabl, Piece of Cake implemented continuous testing (using features like mabl Trainer, Mailbox and AI auto‑healing) that runs on every staging and production deploy. The team saw a 70% reduction in time to create tests, caught numerous defects before production, democratized testing across developers, and now ships updates faster and with greater confidence thanks to mabl.
