testing▌

Conduct effective usability testing using frameworks from 11 product leaders. \n \n Choose the right test fidelity: fake doors and Wizard of Oz tests for concept validation, prototypes for design feedback, production testing for optimization \n Small sample sizes (10 random users) reveal core friction points; direct observation of user behavior uncovers needs that surveys miss \n Test multiple design options simultaneously to measure relative performance, not single designs in isolation \n Bring

Comprehensive testing strategies for Python using pytest, fixtures, mocking, and test-driven development. \n \n Covers unit, integration, functional, and performance testing with the AAA pattern (Arrange, Act, Assert) for test structure \n Includes 10 fundamental and advanced patterns: basic tests, fixtures with setup/teardown, parameterization, mocking, exception handling, async testing, monkeypatching, temporary files, custom fixtures, and property-based testing \n Provides test design princip

Bypass bot detection and CAPTCHA triggers using rebrowser-playwright with stealth techniques. \n \n Uses real GPU rendering, removes WebDriver signatures, and patches fingerprinting vectors to pass bot detection tests like bot.sannysoft.com \n Requires headed mode ( headless: false ) and real Chrome browser ( channel: 'chrome' ) to be effective \n Includes addInitScript to remove navigator.webdriver property, the most common detection method \n For Python, recommends undetected-chromedriver over

Provide systematic methodologies for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities in web applications. This skill covers both database object references and static file references, detection techniques using parameter manipulation and enumeration, exploitation via Burp Suite, and remediation strategies for securing applications against unauthorized access.
