get

public void get​(java.lang.String url)

Load a new web page in the current browser window. This is done using an HTTP POST operation, and the method will block until the load is complete (with the default ‘page load strategy’. This will follow redirects issued either by the server or as a meta-redirect from within the returned HTML. Should a meta-redirect «rest» for any duration of time, it is best to wait until this timeout is over, since should the underlying page change whilst your test is executing the results of future calls against this interface will be against the freshly loaded page. Synonym for WebDriver.Navigation.to(String) . See W3C WebDriver specification for more details.

getTitle

public java.lang.String getTitle()

getCurrentUrl

public java.lang.String getCurrentUrl()

Get a string representing the current URL that the browser is looking at. See W3C WebDriver specification for more details.

getScreenshotAs

public X getScreenshotAs​(OutputType outputType) throws WebDriverException

• Entire page
• Current window
• Visible portion of the current frame
• The screenshot of the entire display containing the browser

• The entire content of the HTML element
• The visible portion of the HTML element

print

public Pdf print​(PrintOptions printOptions) throws WebDriverException

findElement

Find the first WebElement using the given method. This method is affected by the ‘implicit wait’ times in force at the time of execution. The findElement(..) invocation will return a matching row, or try again repeatedly until the configured timeout is reached. findElement should not be used to look for non-present elements, use WebDriver.findElements(By) and assert zero length response instead. See W3C WebDriver specification for more details.

findElements

Find all elements within the current page using the given mechanism. This method is affected by the ‘implicit wait’ times in force at the time of execution. When implicitly waiting, this method will return as soon as there are more than 0 items in the found collection, or will return an empty list if the timeout is reached. See W3C WebDriver specification for more details.

findElements

getPageSource

public java.lang.String getPageSource()

Get the source of the last loaded page. If the page has been modified after loading (for example, by Javascript) there is no guarantee that the returned text is that of the modified page. Please consult the documentation of the particular driver being used to determine whether the returned text reflects the current state of the page or the text last sent by the web server. The page source returned is a representation of the underlying DOM: do not expect it to be formatted or escaped in the same way as the response sent from the web server. Think of it as an artist’s impression. See W3C WebDriver specification for more details.

close

Close the current window, quitting the browser if it’s the last window currently open. See W3C WebDriver specification for more details.

quit

getWindowHandles

public java.util.Set getWindowHandles()

Return a set of window handles which can be used to iterate over all open windows of this WebDriver instance by passing them to WebDriver.switchTo() . WebDriver.Options.window() See W3C WebDriver specification for more details.

getWindowHandle

public java.lang.String getWindowHandle()

Return an opaque handle to this window that uniquely identifies it within this driver instance. This can be used to switch to this window at a later date See W3C WebDriver specification for more details.

executeScript

public java.lang.Object executeScript​(java.lang.String script, java.lang.Object. args)

• For an HTML element, this method returns a WebElement
• For a decimal, a Double is returned
• For a non-decimal number, a Long is returned
• For a boolean, a Boolean is returned
• For all other cases, a String is returned.
• For an array, return a List with each object following the rules above. We support nested lists.
• For a map, return a Map with values following the rules above.
• Unless the value is null or there is no return value, in which null is returned

executeAsyncScript

public java.lang.Object executeAsyncScript​(java.lang.String script, java.lang.Object. args)

• For an HTML element, this method returns a WebElement
• For a number, a Long is returned
• For a boolean, a Boolean is returned
• For all other cases, a String is returned.
• For an array, return a List with each object following the rules above. We support nested lists.
• For a map, return a Map with values following the rules above.
• Unless the value is null or there is no return value, in which null is returned

 long start = System.currentTimeMillis(); ((JavascriptExecutor) driver).executeAsyncScript( "window.setTimeout(arguments[arguments.length - 1], 500);"); System.out.println( "Elapsed time: " + (System.currentTimeMillis() - start)); 

 WebElement composeButton = driver.findElement(By.id("compose-button")); composeButton.click(); ((JavascriptExecutor) driver).executeAsyncScript( "var callback = arguments[arguments.length - 1];" + "mailClient.getComposeWindowWidget().onload(callback);"); driver.switchTo().frame("composeWidget"); driver.findElement(By.id("to")).sendKeys("bog@example.com"); 

 Object response = ((JavascriptExecutor) driver).executeAsyncScript( "var callback = arguments[arguments.length - 1];" + "var xhr = new XMLHttpRequest();" + "xhr.open('GET', '/resource/data.json', true);" + "xhr.onreadystatechange = function() " + ">;" + "xhr.send();"); JsonObject json = new JsonParser().parse((String) response); assertEquals("cheese", json.get("food").getAsString()); 

Script arguments must be a number, a boolean, a String, WebElement, or a List of any combination of the above. An exception will be thrown if the arguments do not meet these criteria. The arguments will be made available to the JavaScript via the «arguments» variable.

Introduction

In this post, we will discuss RemoteWebDriver. First of all, Remote WebDriver is an implementation class of the WebDriver interface that can use to execute test code on a remote machine via the RemoteWebDriver server.

There are two parts to RemoteWebDriver

• Server.(Server is a Java Servlet)
• Client.( The client is the WebDriver test )

Servlet is a Java class that runs in a Web container. Class diagram of RemoteWebDriver

RemoteWebDriver Server

There are two ways to use the server: command line or configured in code. To start the RemoteWebDriver server execute the following command on the remote machine.

For example:
/> java -jar selenium-server-standalone>.jar

The server has 2 different timeouts, which can be set as follows:

java -jar selenium-server-standalone->.jar -timeout=30 -browserTimeout=90

browserTimeout :Controls how long in seconds the browser is allowed to hang.
timeout : Controls how long in seconds the client is allowed to be gone before the session is reclaimed.

Note that : If the Webdriver tests forget to terminate the remote sessions, then the server might leak memory. If you keep long-running sessions, then probably we need to stop/quit the server every now and then or increase memory with -Xmx JVM option. This is the case with limited hardware resources.

Docker Containers

We can fix these issues by running scalable and distributed grid on Docker containers.

Server as Servlet

The process is as simple as mapping the DriverServlet to a URL. Also, it is possible to host the web page in a lightweight container, such as Jetty or dedicated App server container like Tomcat or JBoss, if you run the servers for other purpose.

Remote WebDriver client

When you execute your tests locally, the WebDriver client libraries talk to FireFoxDriver /ChromeDriver/EdgeDriver etc.

When we try to execute the tests remotely, the WebDriver client libraries talk to the RemoteWebDriver server and the server talks to either the FireFoxDriver, ChromeDriver, Edge Driver etc on the Node machines/containers.

Code Snippet

public class SampleCodeExample < public static void main(String[] args)< DesiredCapabilities capabilities =new DesiredCapabilities(); capabilities.setBrowserName("Firefox"); RemoteWebDriver remotedriver =null; try< remotedriver = new RemoteWebDriver (new URL("http:// 127.0.0.1:444/we/hub"),capabilities); >catch (MalformedURLException mfe) < mfe.printStackTrace(); >> >

To customize the browsers and their capabilities consider using FirefoxOptions, ChromeOptions, etc. to run remote Web driver tests.

You can view all of the sessions that are established with the RemoteWebDriver server by navigating to the default URL : http://127.0.0.1:4444/we/hub. ( However, we can configure this too according to our own needs ).

Note that this is old and classic standalone mode. The architecture has significantly changed with Selenium 4 with new Distributed mode that we can leverage some of the limitations and disadvantages.
