java - Cucumber, Java Picocontainer/Constructor injection : TestContext & ScenarioContext),如何在多个步骤定义之间共享多个数据

Question

问题:如何使用构造注入(inject)、依赖注入(inject)/Picocontainer 在多个步骤定义之间共享多个变量/数据以及状态(如果需要)。

背景:我们有一个非常大的步骤定义，管理它变得越来越困难。因此，我们决定使用这个新的自动化基础将步骤定义拆分为多个小定义。

堆栈:Selenium、Java、Cucumber、Junit、Picocontainer。

为了实现上述目标，我们在各种网站和 stackoverflow 讨论中寻找了很多建议，有很多建议，例如使用依赖注入(inject) (Picocontainer)、使用构造函数注入(inject)、spring 等。

在浏览了所有这些建议和页面之后，我们发现了一些灰色区域(在上面的问题中提到)在 stackoverflow 中的任何地方都没有在一个位置/一个答案/一个页面上得到回答，所以我分享这个例子来获得更多信息将帮助初学者和每个人。项目文件结构:

src
|->features
  |----- login.feature
  |----- product.feature
  |----- payment.feature
|->java
  |-->pagefactory
  |    |----- LoginPage.class
  |    |----- ProductPage.class
  |    |----- PaymentPage.class
  |-->picoHelper
  |    |-----TestContext.class   
  |-->stepDefinition
  |    |-----LoginStepDef.class
  |    |-----SearchStepDef.class
  |    |-----ProductStepDef.class
  |    |-----PaymentStepDef.class
  |-->helpers
  |    |-->wait
  |    |-----waitHelper.class
  |    |-->util
  |    |-----DriverFactoryManager.class
  |    |-----PageFactoryManager.class 

通过在步骤定义中注入(inject)上述 testcontext 构造函数，我们能够拆分我们的大定义，并且大多数测试用例都可以正常工作。但是，当我们尝试使用在两个步骤定义之间具有一些共享数据的方法时，问题就来了。

特征文件:

Feature: Verify Product Names and ID are being transferred to Payment Page
  This feature will be used to validate Data


  Scenario: Successful Login with Valid Credentials
    Given User navigate to homepage of portal
    When user enter valid credentials
    Then user should be redirected to homepage


  Scenario: To select the product
    Given User is on product page
    When User select product
    And filterit via productsearch
    Then user should be able to search this product

 Scenario: Payment 
    Given User has selected product
    When User click add to cart
    Then System should display all related info for user to verify

TestContext 看起来像:

public class TestContext {

    private DriverFactoryManager driverFactoryManager;
    private PageObjectManager pageObjectManager;
    public ScenarioContext scenarioContext;

    public TestContext() {
        driverFactoryManager = new DriverFactoryManager();
        pageObjectManager = new PageObjectManager(driverFactoryManager.getDriver());
    }

    public DriverFactoryManager getDriverFactoryManager() {
        return driverFactoryManager;
    }

    public PageObjectManager getPageObjectManager() {

        return pageObjectManager;
    }

}

步骤定义:LoginStepDef

public class LoginStepDef {
    LoginPage lp;
    TestContext testContext;


    private Logger log = LoggerHelper.getLogger(LoginStepDef.class);


    public LoginStepDef(TestContext testContext) throws IOException {
        lp = testContext.getPageObjectManager().getLoginPage();


    }
    //
    methods to login to portal

步骤定义:ProductStepDefs

public class ProductStepDef {
   private Logger log = LoggerHelper.getLogger(ProductStepDef.class);
    TestContext testContext;
    private LoginPage lp;
    private ProductPage objPM;

    String[] prodCodeName = new String[2];
    String[] productDetails;



    public ProductStepDef(TestContext testContext) {
        this.testContext = testContext;
        lp = testContext.getPageObjectManager().getLoginPage();
        objPM = testContext.getPageObjectManager().getProductPage();

   @Then("^user should be able to search this product$")
    public void advancedSearchProduct {

        objPM.advancedSearchProduct(searchKeyword);
        prodCodeName = objPM.productDataProdCodeName();
        log.info("product is: " + prodCodeName[0] + ". Its name is " + prodCodeName[1]); //expected 0 to show id and 1 to show name of product
        productDetails = prodCodeName;
        log.info("productDetails  are : " + productDetails);


    }
    }

步骤定义:PaymentStepDefs

public class PaymentStepDef {

    Logger log = LoggerHelper.getLogger(PaymentStepDef.class);
    LoginPage lp;
    Product objPM;
    PaymentPage objPay;

    String[] prodCodeName = new String[2];
    String[] productDetails;


    public PaymentStepDef(TestContext testContext) {
        this.testContext = testContext;
        lp = testContext.getPageObjectManager().getLoginPage();
        objPM = testContext.getPageObjectManager().getProductPage();
        objPay = testContext.getPageObjectManager().getPaymentPage();



    @Then("^System should display all related info for user to verify$")
    public void verifyExportResult()  {

            exportInfo = objPay.ExportResult(filter1, productDetails, numberOfItems );
            THis Export results, take this productDetails to perform some action to compare with various version and then give perform some validation.
    }

我们想在第 2 个场景中访问用户选择的产品名称和 ID，并在第 3 个场景中进行验证。第二个场景在 ProductStepDefinition 类下，同一特征文件的第三个场景在 PaymentStepDefintion 类中。

有人可以建议一种方法在这个框架之间添加一个类，可以解决在多个定义之间共享不同数据类型的多个数据的问题

Answer 1

Cucumber 不应该以这种方式工作。一种情况的结果不应用作另一种情况的基础。相反，您需要一个 Given 步骤来模拟其他场景所做的。

Feature: Verify Product Names and ID are being transferred to Payment Page
  This feature will be used to validate Data


  Scenario: Successful Login with Valid Credentials
    Given User navigate to homepage of portal
    When user enter valid credentials
    Then user should be redirected to homepage


  Scenario: To select the product
    Given User is on product page
    When User select product
    And filterit via productsearch
    Then user should be able to search this product

 Scenario: Payment
    # Put the product in the database
    Given a product named "Jump Rope" exists
    # Get the product by name, go to product page and add to cart
    When the user adds the "Jump Rope" product to their shopping cart
    # Assert
    Then System should display all related info for user to verify

场景 3 应该通过在双引号内指定名称来将产品放入系统中。 When 步骤会将用户带到产品详细信息页面并单击“添加到购物车”按钮。之后，您现有的 Then 步骤可以进行断言。
