Este capítulo analisa os recursos do Selenium WebDriver que são interoperáveis em diferentes navegadores da Web. Nesse grupo, uma caraterística multiuso relevante é a execução de JavaScript. Além disso, a API do Selenium WebDriver permite configurar timeouts para carregamento de páginas e scripts. Outra caraterística conveniente é a realização de screenshots do ecrã do browser, ou apenas da parte correspondente a um determinado elemento. Em seguida, podemos gerenciar diferentes aspectos do navegador controlado usando o WebDriver, como tamanho e posição do navegador, histórico ou cookies. Em seguida, o WebDriver fornece vários recursos para controlar elementos específicos da Web, como listas suspensas (ou seja, campos de seleção HTML e listas de dados), alvos de navegação (ou seja, Windows, guias, quadros e iframes) ou caixas de diálogo (ou seja, alertas, prompts, confirmações e diálogos modais). Por fim, descobrimos como lidar com dados locais e de sessão usando o armazenamento da Web, implementar ouvintes de eventos e usar as exceções fornecidas pela API do Selenium WebDriver.
