Reusable component class

public class ReusableComponents {
    
    WebDriver driver;

    public ReusableComponents(WebDriver driver) {
        this.driver = driver;
    }
    
    public void setup()  {

        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://opensource-demo.orangehrmlive.com/web/index.php/auth/login");
    }

    public void waitElementToAppear(WebElement findby){
        
        WebDriverWait wait = new WebDriverWait(driver, 30);
        wait.until(ExpectedConditions.visibilityOfElementLocated((By) findby));
                
    }
    
    public void closeBrowser() {
        driver.close();
    }   
}

Test class

public class OpenBrowser {
    static WebDriver driver;

    public static void main(String[] args) {
        
        LoginPage login = new LoginPage(driver);
        ReusableComponents common = new ReusableComponents(driver);
        common.setup();
        common.waitElementToAppear(login.in_username);
        login.enterUname("Admin");
        login.enterPassword("admin123");
        login.clickSubmit();
        common.closeBrowser();

如果我对“用户名称”标的置换式的测试,那么它给我留下的错误就象我在此附上的那样。请有人帮助我解决这个问题?

错误的筛选:

我试图制造一个网点,但却没有帮助。

Answer 1

在您的情形下,当你试图投下一个字标:jdk.proxy2.$Proxy<4/code>至org. openqa.selenium时,便会产生这一问题。通过,这不是有效的投放作业。


在使用“Factory”时,它为附加说明的“FindBy”变量创造了近似值。 职业卫生员负责寻找要素等任务。 例如,当使用司机时,使用限定用途时,它会与代理人进行互动,然后使用实际方法。 因此,这个班子是按班次分类的。
在你的具体情况下,你实际上试图投下一个近似的物体:org. openqa.selenium.remote.RemoteWebElement至org. openqa.selenium。 不允许通过。
通过对你的法典作以下修改,应当解决这一例外情况:
wait.until(ExpectedConditions.visibilityOf(webelement));

Answer 2

请参看下文为我制订的法典。还需要在启动“URL”网站之后再加一等。

// TODO Auto-generated method stub
    WebDriverManager.chromedriver().setup();
    WebDriver driver = new ChromeDriver();
    driver.manage().window().maximize();        
    driver.get("https://opensource-demo.orangehrmlive.com/web/index.php/auth/login");
    Thread.sleep(3000);
    driver.findElement(By.name("username")).sendKeys("Admin");
    driver.findElement(By.name("password")).sendKeys("admin123");
    driver.findElement(By.xpath("//button[@type= submit ]")).click();

Answer 3

In the Page objects and methods class you have used:

PageFactory.initElements(driver, this);

https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/support/PageFactory.html“rel=“nofollow noreferer”>。班次

initElements(SearchContext searchContext, java.lang.Class<T> pageClassToProxy): This method instantiates an instance of the given class, and set a lazy proxy for each of the WebElement and List<WebElement> fields that have been declared, assuming that the field name is also the HTML element s "id" or "name". This method returns an instantiated instance of the class with WebElement and List<WebElement> fields proxied.

因此,@FindBys:

@FindBy(xpath="//input[@name= username ]") public WebElement in_username;
@FindBy(xpath="//input[@name= password ]") WebElement in_password;
@FindBy(xpath="//button[@type= submit ]") WebElement btn_submit;

are proxied fileds. When you try to use those in conjunction with By class:

wait.until(ExpectedConditions.visibilityOfElementLocated((By) findby));

阁下:

Exception in thread "main" java.lang.ClassCastException: class jdk.proxy2.$Proxy4 cannot be cast to class org.openqa.selenium.By (jdk.proxy2.$Proxy4 is in module jdk.proxy2 of loader  app ; org.openqa.selenium.By is in unnamed module of loader  app )

Solution

为等到<><>>>> 用户名<>/code>>> 外地的可见度,并发送一个特性序列,可在<><>上添加两种方法。日本类别如下:

public void LoginPage() { WebElement element = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(LoginPage.getUsernameElement())); email.sendKeys("TestBite"); } public WebElement getUsernameElement() { return in_username; }

Answer 4

您不明确等待有关内容,而是可以在您的网页上添加一个默认的等待时间。

// Set the timeout value (in seconds) as per your needs
PageFactory.initElements(new AjaxElementLocatorFactory(driver, 10), this);
