[Cucumber-JVM] How to identify trigger tag from Scenario api

[Yun Jing]

Hi there,

I have a scenario which applies to different sizes of browser. According to the trigger tag, I want to instantiate a different implementation which implements the same interface. 

For example, there are three implementations (LoginSmallImpl, LoginMediumImpl and LoginBigImpl), I would like to instantiate Login login = new LoginSmallImpl(); if the trigger tag is @small.

I have tried the @Before hook, but it applies to all tags on the scenario. I'm wondering if it's possible to detect the trigger tags?

Cheers.

@small @medium @large
Scenario: Login
  Given I am on the login page
  When I login with a valid username and password
  Then login should be successful

public class LoginSteps
{

  @Before("@small")
  public void small(Scenario sc)
  {

  }

  @Before("@large")
  public void big(Scenario sc)
  {

  }

  @Given("^I am on the login page$")
  public void i_am_on_the_login_page() throws Throwable {

  }

  @When("^I login with a valid username and password$")
  public void i_login_with_a_valid_username_and_password() throws Throwable {

  }

  @Then("^login should be successful$")
  public void login_should_be_successful() throws Throwable {

  }
}

    public static Login runThrough(Scenario scenario) {

        Login login = null;

        for (String tag : scenario.getSourceTagNames()) {
            if (tag.startsWith("@small")) {

                login = new LoginSmallImpl();
            }

            if (tag.startsWith("@medium")) {

                login = new LoginMediumImpl ();
            }

            if (tag.startsWith("@big")) {

                login = new LoginBigImpl();
            }

        }

        return login;
    }

You could try something like this but you may need to know if you already used one of the tags if you want to test this 3 times with different login types or have 3 scenrios with one of those tags each.
