Filipv95
Filip Velkov worked on the ethereum/kohaku-extension, focusing on building and refining automated end-to-end testing infrastructure for browser extension features such as Swap, Bridge, authentication, and network management. He engineered robust Playwright-based test suites in TypeScript and JavaScript, migrating legacy tests and implementing the Page Object Model to improve maintainability and coverage. Filip addressed CI/CD reliability by stabilizing pipelines, optimizing Docker environments, and enhancing selector utilities, which reduced flaky tests and accelerated feedback cycles. His work included refactoring for code clarity, expanding test coverage for edge cases, and aligning test logic with evolving product requirements, resulting in a resilient, scalable QA foundation.

Jul 1, 2025July 2025 (ethereum/kohaku-extension): Delivered a more robust and scalable test framework and related codebase improvements, reinforcing the product’s reliability and reducing release risk. The month focused on refactoring and hardening tests, expanding coverage for edge cases (unknown addresses and balance scenarios), stabilizing CI, and cleaning up the test/integration stack to accelerate feedback and maintenance. Key highlights and impact: - Key features delivered: Refactored transfer tests to improve reliability and coverage; added balance/unknown-address test coverage; scaffolded address book tests; implemented test infrastructure improvements including selector IDs and headless CI support. - Major bugs fixed: Resolved transfer test failures and flaky assertions; fixed CI/test flakiness in sign and token address cases; corrected base page methods and removed unused selectors; resolved merge conflicts and tag cleanup to stabilize the baseline. - Overall impact: Increased confidence in test results, earlier detection of regressions, and smoother CI runs. Expanded coverage for critical user flows (transfers, balances, address book) reduces risk in production deployments. - Technologies/skills demonstrated: Test automation and refactor discipline; CI/headless testing, stability engineering; test data selectors and IDs; Maven/POM build refactor; test infrastructure maintenance and cleanup; cross-cutting focus on reliability and maintainability.

Jun 1, 2025June 2025 monthly summary for ethereum/kohaku-extension focused on expanding automated QA coverage, stabilizing CI, and extending test-driven validation for complex flows. Key features delivered include automated tests for the Swap and Bridge feature with near-complete test coverage, support for bridging tokens with a Smart Account, and the introduction of a pause capability. The month also delivered enhancements to test reliability (selector utilities, timeout handling), and cross-browser/headless testing readiness. Major bug fixes targeted CI reliability, flaky tests, and page-event related failures, enabling faster, more deterministic feedback. Additional work comprised network-management test scaffolding, Chainlist network integration (WIP), and assorted maintenance tasks to align with ambire-common conventions. These efforts collectively improved release confidence, reduced debugging cycles, and expanded end-to-end validation across critical user flows.
