当for循环为空时，元素不可见

Question

I have a for-loop that clicks around a website and testing if the links are working.

But when I enter a page that doesn't have links the test obvious fails. But i cant figure out how to stop the test instead of failing it.

This is my really simple for loop

public void TestT2Links()
{
    int count = LinkElements.Count;
    for (int i = 3; i < count; i++)
    {
        PropertiesCollection.driver.FindElements(By.TagName("a"))[i].Click();
    }
}

Error Log from VS

Result Message:

OpenQA.Selenium.ElementNotVisibleException : element not visible
  (Session info: chrome=40.0.2214.93)
  (Driver info: chromedriver=2.10.267521,platform=Windows NT 6.1 SP1 x86_64)

Result StackTrace:

at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse)
at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
at OpenQA.Selenium.Remote.RemoteWebElement.Click()

Any ideas on how i should stop it?

Answer 1

Add visibility check before you click:

var e = PropertiesCollection.driver.FindElements(By.TagName("a"));
for (int i = 3; i < e.Count; i++) {
    if (e[i].Displayed) {
        e[i].Click();
    }
}
