The @Managed annotation also lets you specify what driver you want to use for a particular test case, via the driver attribute. Current supported values are “firefox”, “iexplorer”, “chrome” and “htmlunit”. The driver attribute lets you override the system-level default driver for specific requirements. For example, the following test case will run in Chrome, regardless of the webdriver.driver system property value used:

@RunWith(ThucydidesRunner.class)
@Story(Application.Search.SearchByKeyword.class)
public class SearchByFoodKeywordStoryTest {

    @Managed(uniqueSession = true, driver="chrome")
    public WebDriver webdriver;

    @ManagedPages(defaultUrl = "http://www.google.co.nz")
    public Pages pages;

    @Steps
    public EndUserSteps endUser;

    @Test
    public void searching_by_keyword_pears_should_display_the_corresponding_article() {
        endUser.is_the_google_home_page();
            endUser.enters("pears");
        endUser.starts_search();
            endUser.should_see_article_with_title_containing("Pear");
    }

    @Test
    @WithDriver("firefox")
    public void searching_by_keyword_pineapples_should_display_the_corresponding_article() {
        endUser.is_the_google_home_page();
            endUser.enters("pineapples");
        endUser.starts_search();
        endUser.should_see_article_with_title_containing("Pineapple");
    }
}

In easyb, you can use the uses_driver directive, as shown here:

using "thucydides"
...
thucydides.uses_default_base_url "http://localhost:9000"
thucydides.uses_driver chrome

...

scenario "The administrator adds a new category to the system",
{
    given "a new category needs to be added to the system",
    {
      administrator.logs_in_to_admin_page_if_first_time()
      administrator.opens_categories_list()
    }
    when "the administrator adds a new category",
    {
       administrator.selects_add_category()
       administrator.adds_new_category("Scala Developers","SCALA")
    }
    then "the system should confirm that the category has been created",
    {
        administrator.should_see_confirmation_message "The Category has been created"
    }
    and "the new category should be visible to job seekers",
    {
        job_seeker.opens_jobs_page()
        job_seeker.should_see_job_category "Scala Developers"
    }
}

In JUnit, you can also use the @WithDriver annotation to specify a driver for an individual test. This will override both the system-level driver and the @Managed annotation’s driver attribute, if provided. For example, the following test will always run in Firefox:

        @Test
        @WithDriver("firefox")
        public void searching_by_keyword_pineapples_should_display_the_corresponding_article() {
            endUser.is_the_google_home_page();
            endUser.enters("pineapples");
            endUser.starts_search();
            endUser.should_see_article_with_title_containing("Pineapple");
        }
