        Puppeteer vs Selenium vs Chai Mocha<\/h2>\n

        Vamos comparar os tr\u00eas frameworks em diferentes aspectos.<\/p>\n

        1. Automa\u00e7\u00e3o de Testes<\/h3>\n

        O Selenium<\/strong> permite testes tanto web quanto mobile<\/strong>, enquanto o Puppeteer<\/strong> \u00e9 focado apenas em navegadores Chrome\/Chromium<\/strong>.
        J\u00e1 o Chai Mocha<\/strong> se destaca por suportar testes ass\u00edncronos<\/strong> e gerar relat\u00f3rios de cobertura<\/strong> com qualquer biblioteca de assertions.<\/p>\n

        \n

        2. Suporte a Navegadores<\/h3>\n
          \n
        • \n

          Puppeteer:<\/strong> compat\u00edvel apenas com Chrome\/Chromium<\/strong>.<\/p>\n<\/li>\n

        • \n

          Chai Mocha:<\/strong> funciona bem com Chrome e Firefox<\/strong>, embora possa ser adaptado a outros navegadores com configura\u00e7\u00f5es adicionais.<\/p>\n<\/li>\n<\/ul>\n

          Resumo:<\/strong>
          Puppeteer \u2192 Chrome
          Selenium \u2192 Multiplataforma
          Chai Mocha \u2192 Chrome e Firefox<\/p>\n

          \n

          3. Suporte a Linguagens<\/h3>\n
            \n
          • \n

            Puppeteer:<\/strong> apenas Node.js<\/strong><\/p>\n<\/li>\n

          • \n

            Selenium:<\/strong> Python, Ruby, JavaScript, Java, C#, PHP<\/strong> e mais<\/p>\n<\/li>\n

          • \n

            Chai Mocha:<\/strong> JavaScript<\/strong><\/p>\n<\/li>\n<\/ul>\n

            \n

            4. Instala\u00e7\u00e3o<\/h3>\n
              \n
            • \n
