Here's Will Schor of @netflixeng.bsky.social at Bug Bash Europe. "Time in production is one of the key ways we gain confidence in our code... but even after a long period of time you can still have latent bugs if you're not writing the right tests."

Testing Datadog's Next-Generation Event Platform Intake with Antithesis | Antithesis
How Datadog's EVP Intake team used Antithesis to test a critical architectural shift from stateless to stateful communication.

Antithesis @antithesis.com · 29/09/2026
“Antithesis caught protocol-breaking bugs in stateful encoding, but what really gave us confidence was seeing it exercise complex timing interleavings that would have been difficult for us to reproduce with our existing tests. The failures it surfaced made us reevaluate how we were testing.”

Why we taught agents to break distributed safety properties | Antithesis
Using mutation testing to validate AI-generated test suites for distributed systems.

Antithesis @antithesis.com · 25/09/2026
Mutation testing is a powerful technique that essentially lets you test your testing. Historically, it's been extremely difficult to mutation test test suites for distributed systems -- we've just solved that with a new Antithesis agent skill that creates deep distributed system bugs.
