尽管在功能文件 calc.feature 中添加了背景，但仍获得 cucumber.runtime.DuplicateStepDefinitionException

Question

我在使用Spring Boot 运行我的Cucumber Selenium 测试时遇到以下错误

我已经在功能文件中添加了Background。不确定如何概括传入其中的参数。

请指导。

错误：

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"

GoogleCalcStepDefinition.java

@Ignore
public class GoogleCalcStepDefinition extends DemoApplicationTests {

    WebDriver driver;
    GoogleSearchPage googleSearchPage;

    @Given("^I open Google$")
    public void I_open_google() {
        this.driver = BrowserConfig.getWebDriver();
        this.googleSearchPage = PageFactory.initElements(driver, GoogleSearchPage.class);
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        driver.get("https://www.google.com");
    }

    @When("^I enter \"([^\"]*)\" in search textbox$")
    public void I_enter_in_search_textbox(String additionTerms) {
        googleSearchPage.searchBox.sendKeys(additionTerms); //passing 2+2 here
        googleSearchPage.searchBtn.click();
    }

    @Then("^I should get result as \"([^\"]*)\"$")
    public void I_should_get_correct_result(String expectedResult) {
        String result = googleSearchPage.calculatorTextBox.getText();
        assertEquals(result, expectedResult); //Verify that result of 2+2 is 4
        BrowserConfig.releaseResources(driver);
    }

Answer 1

除了数值之外，您有两个相同的小黄瓜步骤，并且使用正则表达式将数值参数化，使它们完全相同。因此，虽然小黄瓜中的两个步骤是唯一的，但步骤定义中的绑定是重复的：

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

和

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

两个When 步骤相同。您可以将 Regex 替换为与小黄瓜相同的硬编码值（可能不是您想要的），或者只是删除重复项，因为这些步骤看起来像是在正确处理输入参数。删除 dup 后，gherkin 中的两个步骤都将映射到剩余的单个步骤 def。

根据@Nathaniel 的回复，更新的代码库有助于解决问题。

calc.feature（无需更改）

GoogleCalcStepDefinition .java

@Ignore
public class GoogleCalcStepDefinition extends DemoApplicationTests {

    WebDriver driver;
    GoogleSearchPage googleSearchPage;

    @Given("^I open Google$")
    public void I_open_google() {
        this.driver = BrowserConfig.getWebDriver();
        this.googleSearchPage = PageFactory.initElements(driver, GoogleSearchPage.class);
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        driver.get("https://www.google.com");
    }

    @When("^I enter \"([^\"]*)\" in search textbox$")
    public void I_enter_in_search_textbox(String input) {
        googleSearchPage.searchBox.sendKeys(input); //passing 2+2 and 5*5 here
        googleSearchPage.searchBtn.click();
    }

    @Then("^I should get result as \"([^\"]*)\"$")
    public void I_should_get_correct_result(String expectedResult) {
        String result = googleSearchPage.calculatorTextBox.getText();
        assertEquals(result, expectedResult); //Verify that result of 2+2 is 4 and 5*5 is 25
        BrowserConfig.releaseResources(driver);
    }

}
