PROFILE

Lehnerja

Over a three-month period, contributed to wireapp/wire-webapp and wireapp/wire-desktop by building and refining end-to-end test suites, focusing on modal management, multi-account workflows, and regression coverage for critical user flows. Leveraged TypeScript, Playwright, and React to consolidate modal patterns, expand test parametrization, and introduce environment-driven configuration for flexible deployments. Enhanced test reliability by refactoring locators, stabilizing flaky tests, and improving test data management with FakerJS. Work included comprehensive coverage for features like SSO-driven Terms of Use, read receipts, and multi-account management, resulting in safer releases, consistent UI/UX, and more maintainable automated testing infrastructure across web and desktop applications.

June 2026: Focused on increasing test reliability and expanding end-to-end coverage across wire-webapp and wire-desktop, with a clear emphasis on delivering business value through safer releases and robust QA feedback loops. Key features delivered: - wire-webapp: Test suite stabilization with environment-driven configuration. Consolidated test structure, inline locators, reduced flakiness, and removal of redundant backend references. Replaced hardcoded backend URLs with environment variables to enable secure, flexible configuration across environments. - wire-desktop: End-to-End testing for multi-account management, including account isolation, adding/removing accounts, UI behavior across accounts, and accessibility improvements. Introduced/updated page objects and test utilities to improve reliability and coverage. Major bugs fixed: - Stabilized flaky on-prem login redirect tests in web app by refactoring selectors, coordinating setup with beforeEach/afterEach hooks, and removing brittle interactions. - Reduced maintenance overhead with simpler URL assertions and escaping, lowering false positives from environment changes. Overall impact and accomplishments: - Improved confidence in automated regression suites, enabling safer feature releases and faster feedback cycles across both web and desktop apps. - Achieved broader, more reliable E2E coverage for cross-account scenarios in Wire Desktop, reducing risk for multi-account workflows. - Strengthened test infrastructure and environment flexibility, facilitating secure configuration across on-prem and multi-environment deployments. Technologies/skills demonstrated: - TypeScript/React-based test code, end-to-end testing (page objects, locators, utilities), environment-driven configuration, and accessibility improvements. - Refactoring for reliability, test data management, and maintainability across two major repositories.

May 2026 monthly summary for wire-webapp focused on unifying modal patterns, expanding end-to-end test coverage, and improving maintainability. Implemented a large modal consolidation across key flows by migrating to confirm.modal, removed legacy modal utilities, and eliminated duplicate modal code. Migrated references from dataShareConsent.modal and deleteAccount modal to the confirm.modal flow, simplifying data-sharing consent and account deletion UX. Refactored OpenConversation util to getConversation.open for consistency. Expanded Read Receipts test coverage across assets (pictures, audio, video), link previews, ephemeral messages, and cross-device scenarios, with parametrized tests to improve stability and coverage. Strengthened the test framework and fixtures (connectWithUser) and added a critical E2E test for on-prem redirects (TC-8757). Resolved flaky/test stability issues by skipping flaky tests and trimming assertions. Business impact: reduced modal surface area, consistent UX, faster onboarding of new modals, more reliable end-to-end tests, and clearer traceability to WPB-22420 work items.

In April 2026, two feature-focused test initiatives were shipped in wireapp/wire-webapp, delivering stronger regression coverage for high-risk user flows and reducing test flakiness. Key work focused on SSO-driven Terms of Use disclosure during personal account creation and on robust coverage for Reply functionality (send, receive, and edit) with precise quote handling and notifications. The work aligns with WPB-24831 and WPB-24828, delivering business value through earlier regression detection, more reliable releases, and improved developer productivity.
