在PageFactory / Page Object框架中未初始化@FindBy WebElements

Question

更新的代码：

public class FlightBookingTest extends PageBase{

@Test(priority = 1)
@Parameters({"from", "to"})
public void searchForAPackage(String from, String to) throws InterruptedException {

    customerHomePage().selectDepartureAirport(from);
    customerHomePage().selectDestinationAirport(to);
    customerHomePage().selectStartDate();
    customerHomePage().submitSearchRequest();

    assertThat(searchResultsPage().checkPageTitle(), equalTo("Flight Results"));
}

页面对象：

public class CustomerHomePage extends PageBase {

@FindBy(how = How.XPATH, using = ".//* [@id='container']/div/div[3]/div/div[1]/div/h3")
public WebElement searchResults;  
//loads more locators

public CustomerHomePage(WebDriver driver) {
    this.driver = driver;
    driver.manage().window().maximize();
}

public void visit(String url){
    driver.get(baseURL);
}

public void selectDepartureAirport(String departureAirport) {
    click(whereFromDropdown);
    selectOption(departureAirport);
}

public void selectDestinationAirport(String destination) {
    click(destinationLocator);
    type(destination, destinationLocator);
    selectOption("(" + destination + ")");
}

public void selectFromDate() {
    type("15/07/2016", dateFromField);
}

public void submitSearchRequest() {
    click(submitSearchButton);
    waitForIsDisplayed(searchResults, 120);
}

public void selectStartDate() {
    click(dateFromField);
    click(nextMonthSelector);
    click(dayOfMonth);
}

PageBase：

public class PageBase extends  TestBase {

public CustomerHomePage customerHomePage()
{
    return PageFactory.initElements(driver, CustomerHomePage.class);
}

测试基础：

public class TestBase implements Config {

public WebDriver driver;
//a bunch of methods to handle Driver instantiation and kill

//a bunch of Webdriver utility methods including:
public void click(WebElement element) {
    waitForIsDisplayed(element, 120);
    element.click();
}
 public Boolean waitForIsDisplayed(WebElement element, Integer... timeout) {
    try {
        waitFor(ExpectedConditions.visibilityOf(element),
                (timeout.length > 0 ? timeout[0] : null));
    } catch (org.openqa.selenium.TimeoutException exception) {
        return false;
    }
    return true;
}

private void waitFor(ExpectedCondition<WebElement> condition, Integer timeout) {
    timeout = timeout != null ? timeout : 5;
    WebDriverWait wait = new WebDriverWait(driver, timeout);
    wait.until(condition); //java.lang.reflect.UndeclaredThrowableException HERE...Caused by NoSuchElementException
}

看起来框架没有遵守等待预期的条件-Element的可见性。 我怀疑与'visibilityOf（element）'的实现以及@FindBy初始化元素的方式有关

由以下原因引起：org.openqa.selenium.NoSuchElementException：否这样的元素：无法找到元素：{“ method”：“ xpath”，“ selector”：“ .//*[@ id ='container'] / div / div [3] / div / div [1] / div / h3“}

Answer 1

将您的PageBase类切换到下面。 您早先初始化了代理，但没有返回该实例，只是一个新对象。 另外，您可以使用'this'而不是'CustomerHomePage.class'将initElements行粘贴到CustomerHomePage的构造函数中

public class PageBase extends SeleniumBase {

public CustomerHomePage customerHomePage()
{
    return PageFactory.initElements(driver, CustomerHomePage.class);
}

Answer 2

@FindBy变量名称是drioDownLocator而您传递的变量名称是dropDownContainer 。 您的类中是否还具有WebElement类型的其他变量？
