Getting cucumber.runtime.DuplicateStepDefinitionException despite adding Background in the feature file calc.feature

Question

I am getting following error while running my Cucumber Selenium tests using Spring Boot

I have already added Background in the feature file. Not sure how to generalize the parameters that are getting passed in it.

Please guide.

Error:

calc.feature

Feature: Check addition in Google calculatorcontent
  In order to verify that Google calculator work correctly
  As a user of Google
  I should be able to get correct addition result

  Background: Do some arithmetic on Google
    Given I open Google

  Scenario: Addition
    When I enter "2+2" in search textbox
    Then I should get result as "4"

  Scenario: Multiplication
    When I enter "5*5" in search textbox
    Then I should get result as "25"

Answer 1

You have two gherkin steps that are identical save for the numeric value, and the numeric value was parameterized out with Regex, leaving them completely identical. So while the two steps in the gherkin are unique, the bindings in the step definition are duplicates:

@Then("^I should get result as \"([^\"]*)\"$")

and

@Then("^I should get result as \"([^\"]*)\"$")

Same for the two When steps. You can either replace the Regex with the same hardcoded values as the gherkin (probably not what you want), or simply delete the duplicates since the steps look like they're properly handling the input argument. Once the dups are deleted, the two steps in the gherkin will both map to the single remaining step def.
