Authors Selenium WebDriver tests in any of its 6+ supported languages (Java, Python, JavaScript, C#, Ruby, Kotlin, PHP) - picks the appropriate language binding, configures WebDriver per browser, uses `By.*` locators with the team's accessibility-first preference where supported, runs locally + via Selenium Grid for distributed execution, parses results to JUnit XML. Use for legacy Selenium-locked stacks; new projects pick Playwright or Cypress.
