Instead of: driver.Url = " Thread.Sleep(5000) So now you can write: driver.Url = " IWebElement myDynamicElement = driver.FindElement(By.Id("someDynamicElement")) This way you're telling Selenium to wait up to 5 seconds when it tries to find an element or interact with the page.
ICLOCK 2500 DRIVER
This is how you set an implicit wait: WebDriver driver = new FirefoxDriver() ĭriver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(5)) Once set, the implicit wait is set for the life of the WebDriver object instance. In cases like this you can use Implicit Waits:Īn implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. If all of your pages take around the same time to load, which is longer than expected, then most tests are going to fail due to untimely response. We are going to discuss two types of delays which should cover pretty much all cases you have to deal with: adding a global delay and waiting for something to happen.

ICLOCK 2500 HOW TO
Here I am going to show you how to avoid inserting fixed delays in your tests. You see, there is no winning with arbitrary delays: you either get a slow or a brittle test suite.

The web server, the database and/or the network are overloaded and busy with other requests.A lot of things could contribute to this delay. You have a test that fails intermittently and after some investigation you trace that back to occasional delays in the response For example, you navigate to a page and look or assert for something before the page is fully loaded and your browser automation framework throws an exception indicating the element doesn't exist. Don't worry I'll wait here.Īdding Thread.Sleep (or generally delays) feels like an inevitable hack when it comes to UI testing.
ICLOCK 2500 CODE
Before going any further please read the previous article as I am going to refer to it and its sample code a few times. Much like the previous article the concepts and solutions discussed in this article are applicable regardless of the language and UI framework you use. I am going to use Selenium for the browser automation topics discussed in this article. UI tests fail more frequently then other types of tests, so how can we debug a broken UI test and figure out what caused the failure? In this section I show you how you can capture a screenshot and the page's HTML source when a UI test fails so you can investigate it easier.

So I give you some advice on choosing the right selectors and targeting elements directly when possible. Browser automation frameworks target UI elements using selectors and it's very critical to use good selectors to avoid brittle tests.We discuss why adding fixed delays in UI tests is a bad idea and how you can get rid of them.In this article we are going to discuss a few advanced topics that could help you write more robust tests, and troubleshoot them when they fail: In the last article I talked about a few ideas and patterns, like the Page Object pattern, that help write maintainable UI tests.
