Do While 循环和 ExpectedConditions - 可以一起使用吗？

1. 我使用下面列出的方法遇到了奇怪的无法定位元素/超时异常。

<强>2。是否可以添加一个 while 循环，以便该方法可以多次检查和执行？

    public void waitAndClickElement(WebElement element) throws InterruptedException {
    try {
        this.wait.until(ExpectedConditions.elementToBeClickable(element)).click();
        System.out.println("Successfully clicked on the WebElement: " + "<" + element.toString() + ">");
    }catch (Exception e) {
        System.out.println("Unable to wait and click on WebElement, Exception: " + e.getMessage());
        Assert.assertFalse(true, "Unable to wait and click on the WebElement, using locator: " + "<" + element.toString() + ">");
    }
}

是的，这是可能的。像这样的事情:

    boolean clicked = false;
    int attempts = 0;
    while(!clicked && attempts < 5) {
    try {
            this.wait.until(ExpectedConditions.elementToBeClickable(element)).click();
            System.out.println("Successfully clicked on the WebElement: " + "<" + element.toString() + ">");
            clicked = true;
     } catch (Exception e) {
            System.out.println("Unable to wait and click on WebElement, Exception: " + e.getMessage());
            Assert.assertFalse(true, "Unable to wait and click on the WebElement, using locator: " + "<" + element.toString() + ">");
        }
         attempts++;
    }

在 while 循环中添加最大尝试次数可能是个好主意，这样您就不会陷入无限循环。
