Question

结构..

src/test/java
 config
  TestConfiguration.java
 hooks
  WebDriverHooks.java
 nicebank
  RunSteps.java
  OtherSteps..
 support
  ATMUserInterface.java
  KnowsTheDomain.java

在@Autowired包中放置步骤时，

KnowsTheDomain正在正确注入nicebank。但是，当我将@Autowired和KnowsTheDomain

等帮助程序放入时，我无法WebDriverHooks ATMUserInterface

在自动装配到不同的软件包时是否需要配置注释？我正在运行Cucumber跑步者..

从WebDriverHook.java和ATMUserInterface.java，字段private KnowsTheDomain helper;返回null而不是单例实例。当我运行nicebank包中的步骤时，我需要它们返回它返回的内容。

任何人都知道为什么这个helper字段为空？

TestConfiguration.java

@Configuration
@ComponentScan(basePackages = { "support"})
public class TestConfiguration {
    @Bean
    public static KnowsTheDomain knowsTheDomain() {
        return new KnowsTheDomain();
    }
}

WebDriverHooks.java

@ContextConfiguration(classes = TestConfiguration.class, loader=AnnotationConfigContextLoader.class)
@Configurable(autowire = Autowire.BY_TYPE)
public class WebDriverHooks {
    @Autowired
    private KnowsTheDomain helper;

    @After
    public void finish(Scenario scenario) {
        try {
            byte[] screenshot = 
                        helper.getWebDriver().getScreenshotAs(OutputType.BYTES);
            scenario.embed(screenshot, "image/png");
        } catch (WebDriverException somePlatformsDontSupportScreenshots) {
            System.err.println(somePlatformsDontSupportScreenshots.getMessage());
        }
        finally {
            helper.getWebDriver().close();
        }
    }
}

RunSteps.java - 这会运行Cucumber跑步者..

@RunWith(Cucumber.class)
@CucumberOptions(
        plugin = {"pretty", "html:out"},
        snippets = SnippetType.CAMELCASE,
        features = "classpath:cucumber",
        dryRun = false)
@ContextConfiguration(classes = TestConfiguration.class)
public class RunSteps {

}

KnowsTheDomain.java

@Component
public class KnowsTheDomain {
    private Account myAccount;
    private CashSlot cashSlot;
    private Teller teller;
    private EventFiringWebDriver webDriver;

    public Account getMyAccount() {
        if (myAccount == null) {
            myAccount = new Account();
        }
        return myAccount;
    }
    public CashSlot getCashSlot() {
        if (cashSlot == null) {
            cashSlot = new CashSlot();
        }
        return cashSlot;
    }
    public Teller getTeller() {
        if (teller == null) {
            teller = new ATMUserInterface();
        }
        return teller;
    }
    public EventFiringWebDriver getWebDriver() {
        if (webDriver == null) {
            System.setProperty("webdriver.chrome.driver", "src/test/resources/chromedriver_win32/chromedriver.exe");
            webDriver = new EventFiringWebDriver(new ChromeDriver());
        }
        return webDriver;
    }
}

ATMUserInterface.java

@ContextConfiguration(classes = TestConfiguration.class, loader=AnnotationConfigContextLoader.class)
@Configurable(autowire = Autowire.BY_TYPE)
public class ATMUserInterface implements Teller {
    @Autowired
    private KnowsTheDomain helper;

    @Override
    public void withdrawFrom(Account account, int dollars) {
        try {
            helper.getWebDriver().get("http://localhost:" + ServerHooks.PORT);
            helper.getWebDriver().findElement(By.id("Amount"))
                        .sendKeys(String.valueOf(dollars));
            helper.getWebDriver().findElement(By.id("Withdraw")).click();
        } catch (Exception e) {
            System.err.println("err" + e);
        }
    }
}

Answer 1

@Autowired仅适用于bean。

因此，请确保您在哪里使用@Autowired注释。

将钩子包添加到@ComponentScan，如下所示

@ComponentScan（basePackages = {＆＃34; support＆＃34;，＆＃34; hooks＆＃34;}）

Test Helper Class上的Spring Autowired字段为null
