Why Browser Test Reliability Is Now a Product Decision, Not Just a Framework Decision

Short summary

Browser test reliability is no longer just a framework problem—it's a product decision about whether the testing system provides enough evidence to release. Modern user journeys span identity providers, MFA, streaming AI, feature flags, and canary deployments, making retries and simple timeouts insufficient. Teams must measure cross-environment reliability and connect test evidence directly to deployment versions.

• •Retries hide instability and erode developer trust in test suites
• •Cross-OS differences and complex auth flows require systematic testing strategies
