java - 由于预期条件失败而面临错误：等待警报出现（尝试 5 秒，间隔 500 毫秒）

问题描述

当条件下降时，它进入 else，但当它为 true 时，不进入 if

try {
    //WebDriverWait wait = new WebDriverWait(driver, 5);

    if(wait.until(ExpectedConditions.alertIsPresent()) == null) {
        System.out.println("alert was not present")
        (wait.until(ExpectedConditions.elementToBeClickable(By.xpath("/html/body/div[2]/div/div/div[2]/button[2]"))).click();
        Confirmation.click();
    }
    else {
        String Recipemessage = driver.switchTo().alert().getText();
        System.out.println(Recipemessage);

        if(Recipemessage.equals(alertmessage2) || Recipemessage.equals(alertmessage4) ) {

            Thread.sleep(3000);

            driver.switchTo().alert().accept();
            break;
        }
    }
} catch(Exception exp7) {
    System.out.println(exp7);
}

解决方案

ExpectedConditions.alertIsPresent()永远不会返回null，它将返回警报或抛出TimeoutException

Alert alert = null;
try {
    alert = wait.until(ExpectedConditions.alertIsPresent());
catch(Exception) { }

if(alert == null) {
    System.out.println("alert was not present")
    wait.until(ExpectedConditions.elementToBeClickable(By.xpath("/html/body/div[2]/div/div/div[2]/button[2]"))).click();
    Confirmation.click();
}
else {
    String Recipemessage = alert.getText();
    System.out.println(Recipemessage);

    if (Recipemessage.equals(alertmessage2) || Recipemessage.equals(alertmessage4)) {
        Thread.sleep(3000);
        alert.accept();
        break;
    }
}
