// This could be compressed down to a one-line piece of code like this:
// IWebElement error_Site_AppServerError => new WebDriverWait(DriverInstance.Driver, TimeSpan.FromSeconds(5)).Until((d) => d.FindElement(By.XPath("//*[@id='header']/h1[contains(text(),'Server Error')]"));
// But as one can see, that makes for code that's difficult to read, maintain, and see the intention of.
