Selenium is distributed by Apache 2.
TestNG and similar libraries Can you use Selenium in commercial product? Of course this is not all. Selenium Programming Cookbook 4. It has the follow flow process. First we pass the tests to hub which send this tests to specific nodes where all tests will be executed.
We are going to run the hub server and the two nodes. It offers you to run your selenium test on separate machines in different kinds environments. This is great opportunities. Each nodes will run the tests in different browsers. Selenium Grid are the servers which compounds in distributed nodes. This keys are used for configuration the instance server. The hub server is run on port by default. Will listen on Selenium Grid consists only from one JAR file. We should run this jar with the key -h that to print help information on screen.
This jar has the good help information. It means the this instance will be the hub server. First of all we should run this jar with key -role hub.
Launching Selenium Grid hub Logging initialized ms Such architecture can be scaled easily. Started o. Selenium Grid. High level architecture So all tests and nodes can be located on different machines. It will be taken all receiving tests and distributed to the specific nodes server. Driver class not found: OperaDriver is not re gistered It can be done with key -role node as shown below.
Selenium Grid node is up and ready to register to the hub Started ms Built from revision 41bccdd Driver provider com. Now we can run the new node instance with this configurations. Launching a Selenium Grid node OperaDriver It can have any appropriate name. Firstly we should create the file which has the name. Will try to register ever y ms. We use -nodeConfig that to point which config file to use. Windows 7 6. Nodes should register to https: The same time we should point where is located our hub server by key -hub https: Oracle Corporation Starting auto registration thread.
Registering the node to the hub: Selenium Grid hub is up and running The secondary step is to run the node instance. OperaDriver is not re. The node is registered to the hub and ready to use How you can see above the configuration process can be done by adding the keys in command line. Will try to register ever INFO.
All tests will be executed in this instance in this case. Single Selenium Instance. Selenium Programming Cookbook gistered Figure 5. Chrome Config. The node is registered to the hub and ready to use Sometimes you can need only one instance server.
Program Files x86 GoogleChromeApplicatio nchrome. We set the properties: For this reason you should run the selenium server without keys. Another good opportunities are configure special browsers.
You should see somethings similar: Then the node opens this browser and starts to do the tests. It can look like below: Chrome selenium tests 5. In this example. JUnit is a unit testing framework for the Java programming language.
After you install this plugin. Selenium supports all most popular programming languages: When Selenium executes the test. Selenium can be used only for testing web applications.

This boils down to the test tool's ability to recognize various GUI elements effectively. Selenium WebDriver provides one of the advanced techniques for locating elements on web pages. Locating Elements 8 In this chapter, we will explore more on how to use locator strategies by starting with ID, Name, and Class.
Browsers render visual elements of the application for end users by hiding the HTML code and other resources. When we want to automate interaction with the application using Selenium WebDriver, we need to look carefully at the background code written to render pages and elements in browsers.
We need to identify information such as attribute values and elements structure for locating elements and perform user actions using Selenium WebDriver API. Here is an example of a BMI Calculator application page and HTML code written to render this page in a browser as displayed in the following screenshots: Chapter 1 9 You can view the code written for a page by right-clicking in the browser window and selecting the View Page Source option from the pop-up menu.
This will display the HTML code of the page in a separate window. This might look messy and difficult to understand. We need special tools that can display this information in a structured and easy to understand format.
In this recipe we will briefly explore few of these tools before we dive into locators. How to do it In the following sections we will explore some of the tools which are in-built in browsers and plugins to analyze elements and page structure. Inspecting pages and elements with Firefox using Firebug add-in The newer versions of Firefox provide in-built ways to analyze the page and elements; however, we will use the Firebug add-in which has more powerful features.
You need to install the Firebug add-in in Firefox from https: Locating Elements 10 To inspect an element from the page, move the mouse over the desired element and right-click to open the pop-up menu. Select the Inspect Element with Firebug option as shown in the following screenshot: Chapter 1 11 Firebug provides various other debugging features. For this, select the desired element in the tree and right-click and select Copy XPath or Copy CSS Path option from the pop-up menu as shown in the following screenshot: Inspecting pages and elements with Google Chrome Google Chrome provides an in-built feature to analyze pages and elements.
This is very similar to Firebug. You can move the mouse over a desired element on the page and right-click to open the pop-up menu, then select Inspect element option. This will open Developer Tools in the browser, which displays information similar to that of Firebug, as shown in the following screenshot: Locating Elements 12 Chrome Developer Tools also provide a feature where you can get XPath for an element by right-clicking on the desired element in the tree and selecting the Copy XPath option from the pop-up menu.
Inspecting pages and elements with Internet Explorer Similar to Google Chrome, Microsoft Internet Explorer also provides an in-built feature to analyze pages and elements. To open the Developer Tools, press the F12 key. The Developer Tools section will be displayed as shown in the following screenshot: Chapter 1 13 To inspect an element, click on the pointer icon and hover over the desired element on the page.
Developer Tools will highlight the element with a blue outline and display the HTML code in a tree as shown in the following screenshot: How it works Browser Developer Tools come in handy during test development.
These tools will help you in finding the locator details for elements. These tools parse the code for a page and display the information in a hierarchal tree.
The findElement method returns a WebElement object based on a specified search criteria or throws up an exception if it does not find any element matching the search criteria. The findElements method returns a list of WebElements matching the search criteria.
If no elements are found, it returns an empty list. Find methods take a locator or query object as an instance of By class as an argument.
Selenium WebDriver provides By class to support various locator strategies. The following table lists various locator strategies supported by Selenium WebDriver: FindElement By. Locating elements using id, name, or class attributes is the preferred way to find elements. Let's try using these methods to locate elements as described in the following sections.
Finding elements by the ID attribute Using the id attribute is the most preferable way to locate elements on a page. The W3C standard recommends that developers provide an id attribute for elements that are unique to each element. Having a unique id attribute provides a very explicit and reliable way to locate elements on the page.
While processing the DOM, browsers use id as the preferred way to identify the elements and this provides the fastest locator strategy. Let's now look at how to use id attributes for locating elements on a login form. Chapter 1 17 Downloading the example code You can download the example code files for all Packt books you have downloadd from your account at http: To locate the User Name and Password fields, we can use the id attribute in the following way: You might find multiple elements with similar name attributes and in such a case, the first element on the page with the specified value will be selected, which may not be the element you are looking for.
This may cause the test to fail. When building a testable application, you should recommend that the developers add the id attribute for key elements as well as other unique attributes to enable the easy location of elements. Locating Elements 18 Finding elements by the Class attribute Apart from using the id and name attributes, you can also use the class attribute to locate elements.
The class attribute is provided to apply CSS to an element. You don't have anything in your cart right now.
