The timeout duration is set to 5 seconds. 2. static ExpectedCondition < Boolean > elementToBeSelected(By locator)This condition instructs a command to wait until the locator selects the element. Below is an image representing the elements of PerformanceTiming interface. Download the NuGet using NuGet package manager. The nice thing with this is that you can modify as needed; I have seen several cases where really poorly made websites end up breaking how the ExpectedConditions work, and that was solved with the team writing our own function. An example of using an anonymous function for the explicit scenario above would be something like: And at that point, the function itself could be off on its own in some class in your solution that you can call. and pass it back through to our script. as the penalty for not hitting a successful condition can be expensive.

Lets have a look at a few of the expected conditions: 1. static ExpectedCondition < WebElement > elementToBeClickable(By locator)This condition is used to instruct a command to wait until the element is clickable by the locator. The operation could either be clicking on a hyper-link or clicking on a button or any other operation. Lets see WebDriverWait with an example. The results that are obtained from the Navigation Timing API can be further used to improve the page load time with Selenium testing and also benchmark those results against your competitors web performance. and because the web platform has an intrinsically asynchronous nature, To know more about the fundamentals of Selenium WebDriver, look at this Selenium WebDriver Tutorial. We have the WebDriver Wait classes that simplify this for you. Selenium WebDriver allows for waiting for specific conditions until a defined task is complete.

It would also depend on the platform (desktop, tablet, mobile, etc.) The answers to change to an anonymous function is the most correct one.
