如果找不到输入字段，则跳过代码执行

Question

我需要测试一个案例，其中我有一个随机的额外登录屏幕出现在应用程序中。

WebDriverWait webDriverWait = new WebDriverWait(driver, 4);
WebElement inputBox = webDriverWait.until(ExpectedConditions.visibilityOfElementLocated(By.id("username.input")));

String textInsideInputBox = inputBox.getAttribute("value");

if(!textInsideInputBox.isEmpty())
{
// Insert Search text for Shipping License Plate
insertInputField(driver, "username.input", "warehouse");

// Insert Search text for Serial Number
insertInputField(driver, "password.input", "password");

// Click Authorize button
clickButton(driver, "authorization.authorize.button", "Authorize");
} 

我用这个代码来检测弹出的登录屏幕。但当登录窗口不是时，我当然应该得到waiting for visibility of element located by By.id: username.input。是否可以静默地跳过此代码执行？

Answer 1

您可以简单地使用这样的函数：

public boolean waitForElementToBeVisible(By element) {
try {
wait.until(ExpectedConditions.visibilityOfElementLocated(element));
return true;
}catch (Throwable t){
return false;
}
}

有了它，你可以实现你想要的：

if(waitForElementToBeVisible(By.id("username.input"))){
WebElement inputBox = driver.findElement(By.id("username.input"));
String textInsideInputBox = inputBox.getAttribute("value");

if(!textInsideInputBox.isEmpty())
{
// Insert Search text for Shipping License Plate
insertInputField(driver, "username.input", "datex.local\fp_warehouse");

// Insert Search text for Serial Number
insertInputField(driver, "password.input", "PortalPortal@5655!");

// Click Authorize button
clickButton(driver, "authorization.authorize.button", "Authorize");
} 
}
