Testing & Quality Assurance Frameworks

Testing and QA frameworks enable automated validation, quality gates, and continuous testing across the software development lifecycle. The landscape shows clear specialization by testing domain: Selenium dominates web automation with >40% prevalence in Frontend Testing & QA and >50% in Test Automation positions, while modern alternatives like Cypress (>35% in frontend QA) and Playwright (>15% prevalence) gain traction. Unit testing frameworks align with language ecosystems: JUnit serves Java (>25% in automation QA), Jest powers JavaScript testing (>35% in frontend QA), and pytest dominates Python (>10% prevalence). Mobile testing centers on Appium for cross-platform automation (>70% in Mobile Testing & QA) with platform-specific tools like Espresso for Android and XCTest for iOS. Performance testing is dominated by JMeter (>80% in Performance Testing). API testing relies on Postman (>50% in Backend Testing & QA) and REST Assured (>15% prevalence). Entry-level accessibility is strongest for Selenium (>65% in entry-level automation QA), Cypress, JUnit, and Appium (>70% in mobile QA), making testing skills highly accessible for QA engineering careers. Modern trends favor faster, more reliable frameworks like Playwright and Cypress over traditional Selenium for web testing.
