Unable to launch Selenium Serenity tests on Firefox or Safari due to net.thucydides.core.webdriver.DriverConfigurationError

Question

I am trying to launch Serenity Selenium tests on firefox and safari. The tests works with Chrrome however, when launched using firefox I notice error - net.thucydides.core.webdriver.DriverConfigurationError: WebDriver was unable to create a new instance of type class org.openqa.selenium.firefox.FirefoxDriver.

Sample code:

@Test
public void shouldDisplayHighlightedProductsOnTheWelcomePage() {
    login.as(User.STANDARD_USER);

    List<String> productsOnDisplay = productList.titles();

    assertThat(productsOnDisplay).hasSize(6)
            .contains("Sauce Labs Backpack");
}

serenity.conf looks like this:

    serenity.test.root=serenityswag
    webdriver.driver=firefox
    serenity.take.screenshots=BEFORE_AND_AFTER_EACH_STEP
    serenity.browser.maximized = true

Loginactions.java looks like this:

public class LoginActions extends UIInteractionSteps {
    @Step("Log in as {0}")
    public void as(User user) {
        openUrl("https://www.saucedemo.com/");

        // Login as a standard user
        $("[data-test='username']").sendKeys(user.getUsername());
        $("[data-test='password']").sendKeys(user.getPassword());
        $("[data-test='login-button']").click();
    }

The error I see is following:

    net.thucydides.core.webdriver.DriverConfigurationError: WebDriver was unable to create a new instance of type class org.openqa.selenium.firefox.FirefoxDriver
    WebDriver reported the following message: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Answer 1

The issue with the firefox browser resolved by removing the geckodriver from /usr/local/bin/geckodriver.

The issue with safari browser resolved once Allow Remote Automation enabled from the develop menu
