Case Study: MongoDB accelerates testing and reduces bugs with Antithesis

MongoDB - Customer Case Study

MongoDB, a modern data platform and open-source document database used by over 46,000 organizations, faced the challenge of finding deeply hidden "unknown unknown" bugs in its complex systems. Despite an advanced, homegrown testing infrastructure, some critical bugs only emerged under unpredictable, real-world conditions, posing a risk to their release schedule and product reliability. To address this, they partnered with Antithesis and implemented its testing platform.

The Antithesis platform used deterministic simulation and guided fault injection to test MongoDB's systems under chaotic conditions. This solution successfully uncovered over 100 critical bugs, 75% of which had evaded internal tests, and reduced mean time-to-resolution by 47%. The partnership delivered an estimated 10x ROI, improved release confidence, and freed engineers to focus on feature development instead of debugging.
