Selenium Ie Webdriver Only Works While Debugging

Selenium IE WebDriver only works while debugging

There are a couple of facts which you may have to consider as follows :

First of all:
```
public void waitForPageLoaded(WebDriver driver)
```
looks to me as a pure overhead. There is basically no need to write a separate wrapper function on top of WebDriverWait.

As per the current implementation of WebDriverWait in Selenium v3.8.1 the Constructors are as follows :

WebDriverWait(WebDriver driver, Clock clock, Sleeper sleeper, long timeOutInSeconds, long sleepTimeOut) 
WebDriverWait(WebDriver driver, long timeOutInSeconds)
WebDriverWait(WebDriver driver, long timeOutInSeconds, long sleepInMillis)

It is pretty much unclear how you have implemented:

WebDriverWait(driver, SeleniumConfigurator.TIME_OUT)

The arguments looks error prone.

Again, the until condition
```
d -> ((JavascriptExecutor)d).executeScript("return document.readyState").equals("complete")
```
is a overhead because the Client (i.e. the Web Browser) will never return the control back to the WebDriver instance until and unless 'document.readyState' is equal to "complete". Once this condition is fulfilled Selenium performs the next line of code. Hence the function
```
Boolean org.openqa.selenium.support.ui.FluentWait.until(Function<? super WebDriver, Boolean> arg0)
```
will have no impact.
It's worth to mention that though the Client (i.e. the Web Browser) can return back the control to the WebDriver instance once 'document.readyState' equal to "complete" is achieved, it doesn't guarantees that all the WebElements on the new HTML DOM are VISIBLE, INTERACTABLE and CLICKABLE.
Finally, to address your main issue, I needed a clarification about the node xPath = "//*[@id='link-highlighted']/a" to ensure whether invoking click() opens a new tab or url gets redirected. I don't see you handling either of the cases.

Solution

While dealing with InternetExplorer, keep in mind InternetExplorerDriver runs in a real browser and supports Javascript.

Set the Browser Focus through :

capabilities.setCapability("requireWindowFocus", true);

If click() opens a new window, switch() through the window_handles

Selenium xUnit not working consistently with IE

It appears that this only doesn't work while debugging (stepping through the code). If I just run it it seems to work.

Why is ChromeDriver working in Debug mode but not on release?

Presuming you have installed the NuGet package Selenium.WebDriver.ChromeDriver. You will find the latest chrome driver in \Selenium.WebDriver.ChromeDriver\driver\win32\chromedriver.exe select the correct version based on system.

Add the file to your project, then in the file properties select under "Copy to Output Directory" either "Copy Always" or "Copy if Newer".

How to turn off remote debugging to open this site in IE?

From your description, I think you have configured the site in IE mode site list and tried to automate it in IE mode. It's the expected behavior that you see the error message because you're not using the right way to automate IE mode in Edge.

The right way to automate IE mode in Edge is using IE Driver instead of Edge Driver. For the detailed steps, please follow this guide: Use Internet Explorer Driver to automate IE mode in Microsoft Edge.

Selenium Webdriver - Test fails assert if not running in Debug Mode C# visual studio

You probably just need an explicit wait, try this:

public static bool IsInValidLocation(string invalidLocation)
    {
        By selector = By.XPath("/html/body/header/div/div[4]/div/div/div[2]/div[1]/form/div[2]/span[2]");
        // You might want to research how to construct stable xpaths/selctors
        new WebDriverWait(driver.Instance, TimeSpan.FromSeconds(5)).Until(ExpectedConditions.ElementIsVisible(selector));
        var ErrorMessage = driver.Instance.FindElement(selector);
        bool result = ErrorMessage.Text.Contains(invalidLocation); 
        return result;
    }

The above code will give that message up to 5 seconds to appear, and will throw a timeout exception if it doesn't appear within 5 seconds. You can adjust it to wait longer if needed.
