Selenium + WebDriver + Firefox

Programação Java
#1

Estou com dificuldades em rodar teste funcional. Li alguns artigos mas não estou conseguindo
saber o motivo do erro.
BaseURL está null, não está executando o método a seguir.

Obrigado.

@BeforeClass(alwaysRun = true)
    public void setUp() throws Exception {
        driver = new FirefoxDriver();
        baseUrl = "http://localhost:8080";
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    }

Código está assim

import static org.junit.Assert.*;
import static org.testng.Assert.assertEquals;
import static org.testng.Assert.fail;

import java.util.concurrent.TimeUnit;

public class TestePaginaSoma {

    private WebDriver driver;

        driver.findElement(By.name("calcular")).click();
        assertEquals(driver.findElement(By.cssSelector("h1")).getText(), "O resultado foi 33");
    }

Coloca o BaseURL como uma constante string com valor fixo e use-os nos 2 lugares…

Só uma duvida, você baixou o Driver do Firefox? porque quando ele istancia o FirefoxDriver() ele procura na sua máquina um arquivo de driver do Firefox que precisa estar configurado.

#3

Você precisa fazer uma configuração semelhante a essa :

`

public class SeleniumConfiguration {

private static WebDriver driver;

public static String getProp(String prop) throws IOException {
	Properties props = new Properties();
	FileInputStream file = new FileInputStream("./src/main/resources/selenium.properties");
	props.load(file);
	prop = props.getProperty(prop);
	return prop;
}

@BeforeClass
public static void setUpTest() throws IOException {
	System.setProperty(getProp("selenium.driver"), getProp("selenium.arquivo"));
	setDriver(new ChromeDriver());
}

@AfterClass
public static void tearDownTest() {
	getDriver().close();
	getDriver().quit();
}

public static WebDriver getDriver() {
	return driver;
}

public static void setDriver(WebDriver driver) {
	SeleniumConfiguration.driver = driver;
}

public void waitForElement(WebElement element) {
	WebDriverWait wait = new WebDriverWait(getDriver(), 5);
	wait.until(ExpectedConditions.visibilityOf(element));
}

}

`

Jovem, tente adicionar um web driver wait no seu método setUp

WebDriver driver; webDriverWait = new WebDriverWait(driver, 20)
