问题描述
我正在使用Selenium Standalone Server 3.0.1
.我试图在代码中添加Explicit Wait
,以在元素可见时通过xpath检测元素.为了获得Java帮助,我寻找了Selenium Standalone Server 3.0.1
的源代码,但找不到它.我在selenium-java-2.53.1
版本中找到了源代码.我下载它并找到selenium-java-2.53.1-srcs
,并将其添加到我的Eclipse IDE
中.在FluentWait
的帮助下,我只需将代码复制粘贴到Eclipse IDE
中,然后更改变量名.
I am working with Selenium Standalone Server 3.0.1
. I am trying to add an Explicit Wait
to my code to detect an element through xpath when the element becomes visible. In order to get some Java help I looked out for the source code for Selenium Standalone Server 3.0.1
but was unable to find it. I found the source code in selenium-java-2.53.1
release. I downloaded it and found selenium-java-2.53.1-srcs
and added to my Eclipse IDE
. From the help of FluentWait
, I simply copy pasted the code in my Eclipse IDE
and changed the variable names.
文档中的示例代码如下:
The sample code in documentation is like:
// Waiting 30 seconds for an element to be present on the page, checking
// for its presence once every 5 seconds.
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, SECONDS)
.pollingEvery(5, SECONDS)
.ignoring(NoSuchElementException.class);
WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(By.id("foo"));
}
});
但是当我实现此代码时,只需复制粘贴即可:
But when I implement this code, simply copy pasting it:
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement element = wait.until(new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(By.xpath("//p[text()='WebDriver']"));
}
});
我在FluentWait
类作为The type FluentWait is not generic; it cannot be parameterized with arguments <WebDriver>
这是我的进口货清单:
import java.util.concurrent.TimeUnit;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.Wait;
import com.google.common.base.Function;
有人可以帮我吗?
推荐答案
您需要在等待中指定期望的条件,以下是经过修改的代码,可以解决您的问题.
You need to specify expected condition inside the wait below is the modified code that could solve your problem.
代码:
import java.util.concurrent.TimeUnit;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.FluentWait;
import org.openqa.selenium.support.ui.Wait;
public class DummyClass
{
WebDriver driver;
@Test
public void test()
{
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
until(new Function<WebElement, Boolean>()
{
public Boolean apply(WebElement element)
{
return element.getText().endsWith("04");
}
private void until(Function<WebElement, Boolean> function)
{
driver.findElement(By.linkText("Sample Post2"));
}
}
}
}
这篇关于FluentWait类型不是通用的;不能使用参数< WebDriver>对其进行参数化.通过Selenium和Java的FluentWait类的错误的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
