java sendkeys 错误键应该是一个字符串

Question

尝试使用sendKeys 将用户名和密码传递到表单字段时出现错误。下面是我的用户类，然后是我的测试类。有谁知道为什么应用程序没有传递字符串？

org.openqa.selenium.WebDriverException：未知错误：键应该是字符串

public class User {
    public static String username;
    public static String password;


    public User() {
        this.username = "username";
        this.password = "password";
    }

    public String getUsername(){
        return username;
    }

    public String getPassword(){
        return password;
    }

}

@Test
public void starWebDriver()  {
    driver.get(domainURL.getURL());
    WebElement userInputBox, passInputBox;
    userInputBox = driver.findElement(By.xpath("//input[@name='email']"));
    passInputBox = driver.findElement(By.xpath("//input[@name='password']"));
    System.out.println("before sending keys");
    userInputBox.sendKeys(User.username);
}

Answer 1

您访问的静态属性从未被初始化 (null)，因为构造函数从未被调用。

您可以直接设置静态属性，也可以取出静态上下文并在测试中初始化用户。

例如

public class User {
    public String username;
    public String password;


    public User() {
        this.username = "username";
        this.password = "password";
    }

    public String getUsername(){
        return username;
    }

    public String getPassword(){
        return password;
    }

}


@Test
public void starWebDriver()  {
    User user = new User();

    driver.get(domainURL.getURL());
    ...
    userInputBox.sendKeys(user.username);
}

Answer 2

使用

userInputBox.sendKeys(String.valueOf(User.username));
