如何在PageFactory中使用FluentWait[副本]

Question

public class LoginPage {

    private WebDriver driver;

    public StudioMenuPage(WebDriver driver) {
        this.driver = driver;
        PageFactory.initElements(driver, this);
    }

    @FindBy(xpath = "//div[@class='login']")
    private WebElement loginButton;

    public WebElement getLoginButton() {
        return loginButton;
    }
}


public class TestBase {
public static WebDriver driver = null;

@BeforeTest()
public void initialize() {
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    }
}


public class LoginTest extends TestBase {

LoginPage loginPage;    

@Test
private void makeLogin() {

loginPage = new LoginPage(driver);

// Does not work with Implicit Wait:
/* 
loginPage.getLoginButton().click;
*/


// Works with Thread.sleep:
/* 
Thread.sleep(4000);
loginPage.getLoginButton().click;
*/

// Does not work with Explicit Wait:
/* 
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.elementToBeClickable(loginPage.getLoginButton()));
loginPage.getLoginButton().click;
*/

// Works with FluentWait:
/*  
new FluentWait<>(driver).withTimeout(Duration.ofSeconds(5)).pollingEvery(Duration.ofMillis(500))
    .ignoring(WebDriverException.class)
    .until(d -> {
                    WebElement el = d.findElement(By.xpath("//div[@class='login']"));
                    el.click();
                    return el;
                });
*/
}

如果使用隐式和显式等待器，将发生以下错误：

org.openqa.selenium.WebDriverException: unknown error: Element <div class="login">...</div> is not clickable at point (225, 334). Other element would receive the click: <div id="cdk-overlay-0" class="cdk-overlay-pane" dir="ltr" style="pointer-events: auto; top: 316px; left: 201.5px;">...</div>

第一：我们不应该把隐式和显式的等待混为一谈！这样做会导致不可预测的等待时间。

建议您将PageFactory与AjaxElementLocatorFactory一起使用，它将在访问每个元素时为它们等待指定的秒数，并且忽略CacheLookup标记。

initElements（新的AjaxElementLocatorFactory（驱动程序，15),this）；

protected synchronized void waitForElementVisibilityAndClick(WebElement element, int timeOut, String elementName) {
    protected static Wait<WebDriver> wait = null;
    try {
        wait = new FluentWait<WebDriver>((WebDriver) driver).withTimeout(timeOut, TimeUnit.SECONDS).pollingEvery(1,
                TimeUnit.SECONDS);
        wait.until(ExpectedConditions.visibilityOf(element));
        element.click();
    }catch(Exception e) {
    }
}
