cucumber.runtime.junit.UndefinedThrowable: The step is undefined

Question

I have one scenario for two different classes.

My Cucumber structure:

• Test class:

  @RunWith(Cucumber.class)
  @CucumberOptions(plugin = "pretty", features = "src\\test\\resources\\samuel\\tripleAnd.feature")//and.feature in first case
  public class CucumberTest {
  
  }
  

• Cucumber implementation:

  public class ElementsTestSteps implements En {
  
  public ElementsTestSteps() {
  
      Given("^Element test$", () -> {
  
      });
  
      When("^Using element as \"([^\"]*)\"$", (String arg1) -> {
      });
  
      //Commented on when using the second scenario
      When("^Accept (\\d+) (\\d+)$", (Integer arg1, Integer arg2) -> {
      });
  
      //Commented on when using the first scenario
      When("^Accept (\\d+) (\\d+)$ (\\d+)$", (Integer arg1, Integer arg2, Integer arg3) -> {
      });
  
      Then("^Return (\\d+)$", (Integer arg1) -> {
      });
  }
  
  }
  

• When I use the follow and.feature feature all work well:

  Scenario Outline:
  Given Element test
  When Using element as "and"
  And Accept <switchA> <switchB>
  Then Return <resultSign>
  
  Examples:
    | switchA | switchB | resultSign |
    |       1 |       1 |          1 |
    |       0 |       1 |          0 |
    |       1 |       1 |          1 |
    ...
  

• But when I use the following tripleand.feature feature I get the The step is undefined exception:

  Scenario Outline:
  Given Element test
  When Using element as "triple_And"
  And Accept <switchA> <switchB> <switchC>
  Then Return <resultSign>
  
  Examples:
    | switchA | switchB | switchC | resultSign |
    |       1 |       1 |       1 |          1 |
    |       0 |       1 |       1 |          0 |
    |       1 |       0 |       1 |          0 |
    ...
  

Why is everything going well in the first case but not the second?

Answer 1

You have a simple problem in your below step definition function. You got an extra $ sign after second (\\d+).

When("^Accept (\\\d+) (\\\d+)$ (\\\d+)$", (Integer arg1, Integer arg2, Integer arg3) -> {
    });

Answer 2

Your second accept regexp is wrong. You have $ symbol appearing twice in that expression. $ means end of line EOL. Remove the first $ and it should work fine. Looks like a simple copy paste error.
