We can set the Selenium webdriver to get timeout. There are numerous methods to implement timeouts. They are listed below −setScriptTimeout.pageLoadTimeout.implicitlyWait.The setScriptTimeout is the method to set the time for the webdriver. This is usually applied for an asynchronous test to complete prior throwing an exception. The default value of timeout is 0.This method is generally used for JavaScript commands in Selenium. If we omit setting time for the script, the executeAsyncScript method can encounter failure due to the more time consumed by the JavaScript to complete execution.If the timeout time is set to negative, then the JavaScript can execute ...

We can execute a JavaScript function in Python with Selenium webdriver. DOM interacts with the elements via JavaScript. Selenium is capable of executing JavaScript commands with the execute_script method.Few actions like web scrolling cannot be done by Selenium directly. For this, we shall use the JavaScript Executor. We shall take the help of the JavaScript command window.scrollTo and pass it to the execute_script method. To scroll to the bottom of the page, we have to pass 0 and document.body.scrollHeight as parameters to the window.scrollTo.Syntaxdriver.execute_script("window.scrollTo(0, document.body.scrollHeight);")Examplefrom selenium import webdriver driver = webdriver.Firefox(executable_path="C:\geckodriver.exe") driver.implicitly_wait(0.5) driver.get("https://www.tutorialspoint.com/index.htm") #scroll till page bottom driver.execute_script("window.scrollTo(0, document.body.scrollHeight);)We can ...

We shall explore the prerequisites to learn Selenium. First of all, we should know that testing can be divided into two segments − Manual and Automation.For manual testing, it is essential to have the basic understanding of the application that we are going to test, a reasonable acumen and a good documentation skill.For automation testing, we should learn and develop skills on the basic testing along with automation testing concepts. Apart from these, we should have understanding on the below topicss −DatabaseProgramming logicData StructureFront End Development.Now let us see what major topics we should know under the basic testing concepts ...

We can inspect HTTP response headers with Selenium webdriver. To verify the HTTP header, we should get the response from a source. Some of the HTTP response codes are listed below −5XX − Represents server concerns.4XX − Represents issues in resource detection.3XX − Represents response redirection.2XX − Represents correct ocde.The HttpURLConnection class is used to obtain the HTTP response code. To have a link to an URL, the method openConnection is used. Then, we have to use the setRequestMethod method and pass HEAD as parameter to it.The connect method is applied on the object of the HttpURLConnection class. Finally, the ... Read More

We can automatically download files from a pop up dialog using Selenium webdriver with Python. After clicking the download link, a dialog box appears for the user to select various options to Save the file.We have to programmatically configure the path where the download has to be performed such that every time the Firefox browser is launched, the Firefox profile is proper to perform the download at the desired location.Open the address bar of Firefox, and enter about:config and press Enter . All the browser preferences shall be available with Edit and Toggle buttons. We shall use the Firefox Options ... Read More

We can add custom ExpectedConditions for Selenium webdriver. We require this custom ExpectedConditions when the default expected conditions provided by webdriver are not enough to satisfy some scenarios.The method until is used which is a part of the WebDriverWait class. Here, the ExpectedConditions are used to wait for a specific criteria to be satisfied. This method pauses whenever one of the below incidents happen −The timeout duration specified has elapsed.The criteria defined yields neither false nor null.We can have a custom ExpectedCondition by creating an object of expected criteria and by taking the help of apply method.Let us take an ...

We can get Firefox working with Selenium webdriver on Mac OS. For Firefox versions which are greater than 47, the geckodriver.exe file is to be used. We shall be able to launch the browser only after creating an object of the FirefoxDriver class.SyntaxWebDriver driver=new FirefoxDriver();Visit the link −  https://www.selenium.dev/downloads/ and go to the Browser segment. Click on the Documentation link below Firefox.In the Supported platforms page, click on geckodriver releases link.Then click on the link corresponding to Mac OS.Once downloaded, extract the file and save the geckodriver.exe file to the /usr/local/bin location. As in Windows, we do not need to ... Read More

We can mute all sounds in Chrome with Selenium webdriver. To mute the audio we have to set parameters for the browser. For Chrome, we shall use the ChromeOptions class.We shall create an object of the ChromeOptions class. Then utilize that object to invoke the addArguments method. Then pass −mute−audio as a parameter to that method. Finally, send this information to the driver object.SyntaxChromeOptions op = new ChromeOptions(); op.addArguments("−−mute−audio"); WebDriver d = new ChromeDriver(op);For Firefox, we shall use the FirefoxOptions class and create an object for that class. Then utilize that object to invoke the addPreference method and pass media.volume_scale ... Read More
