By rnavarych
Act as a senior AQA engineer to design test strategies, automate E2E tests with Playwright and Cypress, API validation, performance loads via k6 and JMeter, security scans with OWASP ZAP, mobile automation using Appium across iOS and Android, and optimize CI/CD pipelines with sharding, reporting, and quality gates.
API test automation with Postman/Newman, REST Assured, SuperTest, and httpx. Contract testing (Pact, consumer-driven), schema validation (JSON Schema, OpenAPI), mock servers (WireMock, MSW), API performance baselines, and auth token management. Use when testing REST/GraphQL APIs or setting up API test infrastructure.
CI/CD test integration: parallel test execution (sharding), test splitting strategies, flaky test quarantine, test reporting (Allure, ReportPortal, JUnit XML), quality gates (coverage thresholds, no new failures), test result caching, and pre-commit hooks. Use when configuring test pipelines, optimizing CI test execution, or setting up reporting.
End-to-end test automation with Playwright (codegen, trace viewer, MCP, sharding, visual comparisons, fixtures, component testing), Cypress v13, Selenium 4 (BiDi), WebdriverIO, TestCafe, Robot Framework. Visual regression: Percy, Chromatic, Applitools, BackstopJS, Lost Pixel. Cross-browser: BrowserStack, Sauce Labs. Accessibility in E2E.
Mobile test automation with Appium (cross-platform), Detox (React Native gray-box), XCUITest (iOS native), Espresso (Android native), device farms (BrowserStack, Sauce Labs, AWS Device Farm), screenshot testing, gesture testing, and deep link testing. Use when automating mobile app tests or setting up mobile test infrastructure.
Performance test design and execution with k6 (JavaScript, cloud execution, thresholds), JMeter (GUI, distributed), Gatling (Scala DSL), and Artillery (YAML config). Load, stress, soak, and spike testing. Baselines, bottleneck analysis, CI performance gates, custom metrics, and result analysis.
