- 1. Selenium Training in Chennai Demo Part-1 By Creating Experts Contact 8122241286 http://thecreatingexperts.com/selenium-training-in-chennai/
- 2. Introduction to Selenium Selenium is a free (open source) automated testing suite for web applications across different browsers and platforms. It is quite similar to HP Quick Test Pro (QTP) only that Selenium focuses on automating web-based applications. Selenium is not just a single tool but a suite of software's, each catering to different testing needs of an organization. It has four components. •Selenium Integrated Development Environment (IDE) •Selenium Remote Control (RC) •WebDriver •Selenium Grid
- 3. Installing Selenuim IDE & FireBug Installation of Selenium IDE What you need •Mozilla Firefox •Active Internet Connection If you do not have Mozilla Firefox yet, you can download it from http://www.mozilla.org/en-US/firefox/new. Steps •Launch Firefox and navigate to http://seleniumhq.org/download/. Under the Selenium IDE section, click on the link that shows the current version number. •For security, a Firefox notification will pop up. Click on "Allow."
- 4. •Wait until Firefox completes the download and then click "Install Now." •Wait until the installation is completed. In the pop-up window, click "Restart Now." After Firefox has restarted, launch Selenium IDE using either of two ways: •By pressing Ctrl+Alt+S •By clicking on the Firefox menu button > Web Developer> Selenium IDE •Selenium IDE should launch
- 5. Installation of Firebug Firebug is a Firefox add-on that we will use to inspect the HTML elements of the web application under test. It will provide us the name of the element that our Selenese command would act upon. Step 1 •Use Firefox to navigate to Firebug's download page (https://getfirebug.com/downloads/) and click on the download link. Step 2 •Firefox will take you to its Firebug download section. Click the "Add to Firefox" button. Step 3 •Wait for Firefox to complete downloading this add-on. On the dialog box that comes after, click "Install Now."
- 6. Step 4 •Wait for the installation to complete. A notification will pop-up saying, "Firebug has been installed successfully." You can immediately close this pop-up. Step 5 •Launch Firebug by doing either of these two methods: •Press F12 •Click on the Firebug button on the upper right corner of the Firefox window. Step 6 •Firebug should launch at the bottom of Firefox as shown below
- 7. Introduction to Selenium IDE • Selenium IDE (Integrated Development Environment) is the simplest tool in the Selenium Suite. It is a Firefox add-on that creates tests very quickly through its record-and-playback functionality. This feature is similar to that of QTP. It is effortless to install and easy to learn. • Because of its simplicity, Selenium IDE should only be used as a prototyping tool - not an overall solution for developing and maintaining complex test suites.
- 8. • Though you will be able to use Selenium IDE without prior knowledge in programming, you should at least be familiar with HTML, JavaScript, and the DOM (Document Object Model) to utilize this tool to its full potential. Knowledge of JavaScript will be required when we get to the section about the Selenese command "runScript". • Selenium IDE supports autocomplete mode when creating tests. This feature serves two purposes: • It helps the tester to enter commands more quickly. • It restricts the user from entering invalid commands.
- 9. Creating your First Selenium IDE script •Create a Script by Recording •Let us now create our first test script in Selenium IDE using the most common method - by recording. Afterward, we shall execute our script using the playback feature. Step 1 •Launch Firefox and Selenium IDE. •Type the value for our Base URL: http://newtours.demoaut.com/. •Toggle the Record button on (if it is not yet toggled on by default). Step 2 •In Firefox, navigate to http://newtours.demoaut.com/.
- 10. Step 3 •Right-click on any blank space within the page, like on the Mercury Tours logo on the upper left corner. This will bring up the Selenium IDE context menu. Note: Do not click on any hyperlinked objects or images •Select the "Show Available Commands" option. •Then, select "assertTitle exact: Welcome: Mercury Tours". This is a command that makes sure that the page title is correct. Step 4 •In the "User Name" text box of Mercury Tours, type an invalid username, "invalidUN". •In the "Password" text box, type an invalid password, "invalidPW".
- 11. Step 5 •Click on the "Sign-In" button. Step 6 •Toggle the record button off to stop recording. Step 7 •Now that we are done with our test script, we shall save it in a test case. In the File menu, select "Save Test Case". Alternatively, you can simply press Ctrl+S. Step 8 •Choose your desired location, and then name the test case as "Invalid_login". •Click the "Save" button.
- 12. Step 9. •Notice that the file was saved as HTML. Step 10. •Go back to Selenium IDE and click the Playback button to execute the whole script. Selenium IDE should be able to replicate everything flawlessly.
- 13. How to use Locators in Selenium IDE • Locators tell Selenium IDE which GUI elements ( say Text Box, Buttons, Check Boxes etc) its needs to operate on. • Identification of correct GUI elements is a prerequisite to create an automation script. But accurate identification of GUI elements is more difficult than it sounds. • Sometimes, you end up working with incorrect GUI elements or no elements at all! Hence, Selenium provides a number of Locators to precisely locate a GUI element
- 14. The different types of locator are: • ID • Name • Link Text • CSS Selector • Tag and ID • Tag and class • Tag and attribute • Tag, class, and attribute • Inner text • DOM (Document Object Model) • getElementById • getElementsByName
- 15. • dom:name • dom: index • XPath • There are commands that do not need a locator (such as the "open" command). However, most of them do need Locators. • The choice of locator depends largely on your Application Under Test. In this tutorial, we will toggle between facebook, new tours.demoaut on the basis of locators that these applications support. Likewise in your testing project you will select any of the above listed locators based on your application support.
- 16. How to enhance a script using Selenium IDE Verify Presence of an Element We can use following two commands to verify the presence of an element: •verifyElementPresent - returns TRUE if the specified element was FOUND in the page; FALSE if otherwise •verifyElementNotPresent - returns TRUE if the specified element was NOT FOUND anywhere in the page; FALSE if it is present. •The test script below verifies that the UserName text box is present within the Mercury Tours homepage while the First Name text box is not. The First Name text box is actually an element present in the Registration page of Mercury Tours, not in the homepage. strong>Verify Presence of a Certain Text
