Boa tarde.

Estou tendo esse erro desde a primeira tentativa de realizar o código da primeira aula. já atualizei os drives(Tanto do Firefox como do Chrome), estou utilizando a versão mais recente do Selenium e nada funciona.

Código:

WebDriver driver = new ChromeDriver();
        driver.get("https://www.google.com.br/");
        WebElement q = driver.findElement(By.name("q"));
        q.sendKeys("Caelum");
        q.submit();

erro:

INFORMAÇÕES: Using `new FirefoxOptions()` is preferred to `DesiredCapabilities.firefox()`
Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Oi Gabriel, não sou um super especialista em selenium, mas dando uma olhada na internet parece que o problema pode ter a ver com alguma instalação em um local customizado do firefox ou chrome. https://github.com/SeleniumHQ/selenium/issues/2672

Talvez você tenha que usar o System.setProperty e definir o caminho na mão.

Alberto já fiz isso diversas vezes o erro continua.

Mas percebi um comportamento, se eu executo o drive ou do Firefox ou do Chrome, e executo o código o erro muda.

mas tbm não achei resolução para esse, já baixei diversas versões do Selenium, atualizei os navegadores, já configurei variável de ambiente mas nada funciona.

Eu parei o curso, pq realmente estou empacado nesse erro, olhei o fórum inteiro do curso aqui na Alura e não tem nenhuma dúvida igual que possa me ajudar

solução!

Resolvido, na verdade nao sei o que era, o projeto parece que estava com problema, exclui e fiz outro e agora está funcionando.
