java - Pagefactory 在页面对象结构中抛出 null

Question

我正在我的页面对象模型自动化框架中实现 pagefactory。我现有的框架在没有 pagefactory 的情况下工作正常。现在我正在实现 pagefactory 来调用元素。我面临一个问题，即 Pagefactory 元素抛出空值。我怀疑这可能是因为构造函数不确定。

我已经构建了一个基于页面对象模型的框架有以下套餐:-com.automationframeworkcom.配置com.pageObjectcom.testcasescom.testsuites

我的测试套件类调用测试用例包中存在的测试用例，并调用自动化框架中的驱动程序和其他基于框架的类。我知道仅仅阅读一些内容很难捕获错误，但可能有人遇到同样的问题并可以帮助我。

我的页面类如下所示:-

public class SynchronizationPage extends Page {

    ExcelLib xl = new ExcelLib();

    private WebElement element = null;

    public SynchronizationPage(WebDriver driver) {
        super(driver);
    }

    protected boolean isSecured() {
        return true;
    }

    @FindBy(how = How.XPATH, using = "//a[@class='header-font']/span[@class='icon-cog']")
    @CacheLookup
    public WebElement HoverOnSettings;
}

我的测试用例类:-

public class SyncTest extends AutomationTestCaseVerification {

//  SynchronizationPage sync = new SynchronizationPage(Page.driver);
    SignOutPage signout = new SignOutPage(Page.driver);
    ExcelLib xl = new ExcelLib();
    SynchronizationPage synccc = PageFactory.initElements(Page.driver, SynchronizationPage.class);

    private WebElement element = null;
    private WebDriver driver;

    public SyncTest() {
        super();
    }


    @Override
    protected void verifyTestCases() throws Exception {
        syncFeature();
    }

    public void syncFeature() throws Exception {

        try {
         WebDriverWait waits = new WebDriverWait(Page.driver, 60);
    //   waits.until(ExpectedConditions.elementToBeClickable(synccc.clickOnOffButton)).click();
         synccc.clickOnOffButton.click();
         System.out.println("Yes I clicked");
        }
        catch(Exception ex)
        {
            System.out.println("error ="+ex.getMessage());
            }

    }
}

我收到如下错误:-

我也尝试过在下面申请，但仍然不起作用:-

PageFactory.initElements(this.driver, this);

Answer 1

您可以通过在 SynchronizationPage 类的构造函数中调用 PageFactory.initElements(driver, this); 来尝试一次吗？
