Test Automation Engineer

Professional Summary :

Results-oriented QA and Test Automation Engineer with 5+ years of professional experience specializing in building robust automation frameworks for macOS applications.

Expert in designing, developing, and maintaining automated UI and functional test suites using Swift, XCTest, and XCUITest, with proven success in testing complex desktop/macOS applications at scale.

Adept at working across the full software development lifecycle, from test strategy design and execution to CI/CD automation and post-release validation.

Recognized for strong debugging, problem-solving, and the ability to create scalable, maintainable, and reusable automation solutions that accelerate product delivery while ensuring high quality.

Core Skills and Experience :

UI Automation Expertise :

- Deep hands-on experience with macOS UI automation using XCTest/XCUITest, including handling system-level dialogs, accessibility layers, asynchronous operations, window management, and inter-app communication.

- Ability to design abstraction layers for test cases, increasing reusability and reducing maintenance costs.

macOS Platform Knowledge :

- Strong understanding of macOS architecture, Cocoa frameworks, accessibility APIs, application lifecycle, and unique UI patterns within Apples ecosystem.

- Skilled at testing apps integrating with macOS System Preferences, Finder, Launch Services, and Sandbox/environment restrictions.

Test Architecture & Design Patterns :

- Hands-on experience implementing automation design patterns like Page Object Model (POM), Factory, Singleton, and Dependency Injection for cleaner test code and better maintainability.

- Built mocking/stubbing frameworks to isolate complex services, simulate failure scenarios, and ensure stable, environment-independent test runs.

CI/CD Pipeline & DevOps Integration :

- Proficient in integrating automation test suites into Jenkins, GitHub Actions, and GitLab CI, enabling nightly builds, regression checks, and test reporting dashboards.

- Experience with parallel test execution, test sharding, and distributed execution to optimize test cycle time.

- Skilled in generating custom test reports (HTML, JUnit, Allure) for better visibility into test runs.

Development Skills :

- Strong in Swift programming, leveraging advanced language features (protocol-oriented programming, generics, extensions) to build robust automation frameworks.

- Fluency in Xcode CLI, Instruments, LLDB (debugger), and advanced debugging methodologies to triage and resolve test/application issues effectively.

- Familiarity with REST APIs, JSON, and mock server integration for validating client-server communication in macOS apps.

Agile & Collaboration :

- Strong experience in Agile/Scrum-based environments, collaborating with product owners, developers, and QA engineers to refine acceptance criteria and testing strategies.

- Skilled in Git-based workflows (GitFlow, trunk-based development) for version control and collaboration.

Quality Advocacy & Best Practices :

- Promote shift-left testing approaches, ensuring quality is embedded from design stage onward.

- Conducted code reviews, test strategy reviews, and automation workshops to mentor teams and disseminate best practices.

- Continuously drive improvements in automation coverage, scalability, performance, and reliability testing, aligning with product growth.

Performance & Scalability Testing :

- Ability to extend UI automation to measure performance bottlenecks, resource utilization, and system stability metrics during sustained automation runs.

- Hands-on with profiling tools like Xcode Instruments (Time Profiler, Memory Graph) for performance analysis.

Key Achievements (Examples you could customize) :

- Designed and implemented a modular macOS automation framework from scratch, reducing manual regression testing effort by 65%.

- Automated end-to-end test coverage for complex workflows with multi-window, multi-threaded UI interactions.

- Integrated automated regression suite into nightly CI/CD pipeline, cutting down release cycle validation time by 50%.

- Proactively identified and reported critical macOS compatibility issues during OS upgrades, preventing production failures.
