在下面的第 33 行代码中,在 wait.until 附近出现以下错误消息
该行有多个标记 - 无法解析 com.google.common.base.Function 类型。它是从所需的 .class 文件间接引用的 - FluentWait类型中的方法until(Function)不适用于 参数(预期条件)

最佳答案
您看到的错误如下:
Multiple markers at this line - The type com.google.common.base.Function cannot be resolved. It is indirectly referenced from required .class files - The method until(Function) in the type FluentWait is not applicable for the arguments (ExpectedCondition)
让我们分析一下代码中发生了什么。
在页面对象
中,您已将WebElement
定义为:
@FindBy(xpath = "//input[@ng-model='login.username']")
private WebElement userName;
继续前进,您已尝试在方法中使用 WebElement
:
public void logIn(String uName, String Pswd) throws InterruptedException {
WebDriverWait wait=new WebDriverWait(driver,7);
wait.until(ExpectedConditions.visibilityOf(userName));
//
}
所以基本上我们在这里试图等待间接引用 Angular WebElement
userName 的可见性取决于属性 ng-model
。在这种情况下,我们永远无法确定在方法 userName 中引用 WebElement
时是否会强制引用not NULL 值。它也可能是NULL
。
现在让我们看一下visibilityOf
的方法定义,它的定义为:
visibilityOf(WebElement element)
An expectation for checking that an element, known to be present on the DOM of a page, is visible.
很明显,visibilityOf
方法需要WebElement
的直接引用。因此,在 userName
缺乏确定值(not NULL)的情况下,WebDriverWait
这是 FluentWait
的变体,显示错误。
关于java - wait.until(ExpectedConditions.visibilityOf(userName)) 不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/47656980/
