Aug 1, 2025Monthly summary for 2025-08 (mullvadvpn-app): This month focused on reliability, maintainability, and release readiness, delivering testing standardization, targeted refactors, and stability improvements that reduce risk in production releases. Key actions include standardizing tests with TestCoroutineRule across all view model tests, adding documentation for the rule, and enforcing consistency via Konsist tests; architectural refactor to replace select hop code with use cases; bug fix for location list navigation. Additional improvements cover payment-flow testing and enhanced account data fetching, together with substantial release readiness work (Android version bumps to 2025.6-beta3 and 2025.6, 2025.7-beta1, and associated changelogs), along with dependency updates (Jetpack Compose 1.9.0, core-ktx 1.17.0) and localization updates. Quality and automation were bolstered by UI Automator updates, test orchestrator enhancements, and lint fixes, plus stability efforts to disable flaky tests and fix end-to-end failures. Overall impact: higher release confidence, faster iteration on critical flows (payments and location), and improved code maintainability for future updates.
