java 中黄瓜步骤之间共享状态的实现

Question

我有两页对象，分别称为 OrderSelection 和 OrderDetails。另外，我还有SharedStateclass和OrderSelectionStepDef和OrderDetailsStepDef。我在 SharedState 中为 OrderSelection 和 OrderDetails 声明了两个变量。但是，它们没有在 SharedState 的构造函数中初始化。在 OrderSelectionStepDef 和 OrderDetailsStepDef classes 中，我声明了它们的构造函数并传递了 SharedState 对象。

public OrderSelectionStepDef(SharedState sharedState) {
  this.sharedState = sharedState;
}    
public OrderDetailsStepDef(SharedState sharedState) {
  this.sharedState = sharedState;
}

当我在 OrderDetailsStepDef 或 OrderSelectionStepDef 中调用 sharedState.orderDetails 时抛出了 NullPointerException。

然后，我在 SharedState 构造函数中初始化 OrderSelection 和 OrderDetails class 对象。然后问题就解决了。但是这个实现是否适合黄瓜 pico 容器概念？

Answer 1

第 1 步。OrderSelectionStepDef 和 OrderDetailsStepDef 如下所示（请根据您的实施更改名称）

/**
 * Step Definition implementation class for Cucumber Steps defined in Feature file
 */

public class HomePageSteps extends BaseSteps {

    TestContext testContext;

    public HomePageSteps(TestContext context) {
        testContext = context;
    }

    @When("^User is on Brand Home Page (.+)$")
    public void user_is_on_Brand_Home_Page(String siteName) throws InterruptedException {
        homePage = new HomePage().launchBrandSite(siteName);
        testContext.scenarioContext.setContext(Context.HOMEPAGE, homePage);
    }

    @Then("^Clicking on Sign In link shall take user to Sign In Page$")
    public void clicking_on_Sign_In_link_shall_take_user_to_Sign_In_Page() {
        homePage = (HomePage) testContext.scenarioContext.getContext(Context.HOMEPAGE);
        signInPage = homePage.ecommSignInPageNavigation();
        testContext.scenarioContext.setContext(Context.SIGNINPAGE, signInPage);
    }

供大家参考

public class BaseSteps {

    protected HomePage homePage;
    protected PLPPage plpPage;
    protected PDPPage pdpPage;
    protected ShoppingBagPage shoppingBagPage;
    protected ShippingPage shippingPage;

More implementation goes here.....  

}

步骤2.请在你的框架下添加下面2个类 -

首先，Java文件名-ScenarioContext.java

public class ScenarioContext {

    private  Map<String, Object> scenarioContext;

    public ScenarioContext(){
        scenarioContext = new HashMap<String, Object>();
    }

    public void setContext(Context key, Object value) {
        scenarioContext.put(key.toString(), value);
    }

    public Object getContext(Context key){
        return scenarioContext.get(key.toString());
    }

    public Boolean isContains(Context key){
        return scenarioContext.containsKey(key.toString());
    }
}

二、Java文件名-TestContext.java

public class TestContext {

    public ScenarioContext scenarioContext;

    public TestContext(){
        scenarioContext = new ScenarioContext();
    }

    public ScenarioContext getScenarioContext() {
        return scenarioContext;
    }
}

步骤 3. POM 依赖性 - picocontainer 应根据您的黄瓜版本

   <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-picocontainer</artifactId>
        <version>${cucumber.version}</version>
    </dependency>

希望对您有所帮助。
