Java Selenium WebDriver无法将第一个项目放入购物篮

Question

Following is short program & in the following web site: https://uk.webuy.com/search/index.php?stext= *&section=&catid=956

I am trying to click the first three product's "I want to buy this item" button & view them in the VIEW BASKET at the right side of the page.

For some reason, I am able to see the second and third product only. For some reason, the first product never makes it to the basket, & it does not produce an error.

Only when I change the following line:

 allButtons.get(0).click();

to:

allButtons.get(0).click();
  allButtons.get(0).click();
  allButtons.get(0).click();

I will see one occurrence of the first product in the basket.

What am I doing wrong? Is there something missing that is causing this problem?

Using Java 1.8 Selenium WebDrive Version #2.48 Mac OS Version #10.11.13

Thank you

Answer 1

Your browser could not render that first button. you may put wait.until() method before each click event. try this

    WebDriverWait wait = new WebDriverWait(driver,120);
    wait.until(ExpectedConditions.elementToBeClickable(By.xpath("/html/body/div[5]/div[1]/div[3]/div[5]/div[1]/div[1]/div[3]/div/a[1]/div/span")));
    allButtons.get(0).click();

Answer 2

Your code isn't functional. Popup closing logic doesn't work, its actually not a separate window, its a dialog box within the same window. You should also consider simplifying your selectors. Alright enough said, here is working and tested code.

WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver, 30);
driver.get("https://uk.webuy.com/search/index.php?stext=*&section=&catid=956");
WebElement element;
try {
    element = driver.findElement(By.cssSelector(".deliver-component-wrapper>a>div"));
    System.out.println("Closing pop up");
    element.click();
} catch (NoSuchElementException e) {
    System.out.println("Alright, no such dialog box, move on");
}

List<WebElement> buyButtons = wait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.cssSelector(
        "span.listBuyButton_mx")));
Assert.assertTrue("Less than three buttons found", buyButtons.size() >= 3);
for (int i = 0; i < 3; i++) {
    WebElement buyButton = buyButtons.get(i);
    wait.until(ExpectedConditions.elementToBeClickable(buyButton)).click();
    System.out.println("Clicked Buy Button " + (i + 1));
}
WebElement basketCount = wait
        .until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("#buyBasketRow>td.basketTableCell")));
System.out.println(basketCount.getText());
driver.quit(); 

It prints

Closing pop up
Clicked Buy Button 1
Clicked Buy Button 2
Clicked Buy Button 3
3 item/s
