Selenium 等到预期条件

Question

我正在尝试搜索某些内容，单击搜索按钮后，该按钮进入加载 animation。 如果有结果，则转到下一页，如果没有结果，则会出现一个黄色框。 我该如何编写这一行new WebDriverWait(driver, 1).until ？ 我在想直到标题改变或黄色框出现。 但我不确定我该如何编码。

这是我到目前为止得到的

new WebDriverWait(driver, 1).until(driver.getTitle().contains("Overview") || !driver.findElements(By
                    .xpath("/html/body/div[2]/div/div[3]/div/div[1]/div/div/div[2]/div[2]/div/div[1]/div/div/div/span"));
                    .isEmpty())

Answer 1

使用org.openqa.selenium.support.ui.ExpectedConditions

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public WebDriverWait waitSec(WebDriver driver, int sec) {
    return new WebDriverWait(driver, sec);
}

public WebElement clickableByXpath(String xpath, int sec) {
    WebElement element = waitSec(driver, sec).until(ExpectedConditions.elementToBeClickable(By.xpath(xpath)));
    return element;
}
  
public WebElement clickableById(String id, int sec) {
    WebElement element = waitSec(driver, sec).until(ExpectedConditions.elementToBeClickable(By.id(id)));
    return element;
}
  
public WebElement visibleById(String id, int sec) {
    WebElement element = waitSec(driver, sec).until(ExpectedConditions.visibilityOfElementLocated(By.id(id)));
    return element;
}
  
public WebElement visibleByXpath(String xpath, int sec) {
    WebElement element = waitSec(driver, sec).until(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath)));
    return element;
}


// custom ExpectedCondition
public ExpectedCondition<Boolean> elementNotVisible(String xpath) {
    return ExpectedConditions.not(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath)));
}
