QSpiders - Automation using Selenium
- 2. Automation Introduction Automation is the integration of testing tools into the test environment in such a manner that the test execution, logging, and comparison of results are done with little human intervention. A testing tool is a software application which helps automate
- 3. Features of Automation Testing workbenches provide a range of tools to reduce the time required and total testing costs. Systems such as Junit support the automatic execution of tests. Most testing workbenches are open systems because testing needs are organisation-specific. They are sometimes difficult to
- 4. Advantages of Automation Testing Automated testing is cheaper. Automated testing is faster. Automated testing is more reliable. Automated testing reduces human and technical risks. Automated testing is more powerful and versatile.
- 5. Overview of Supported Technologies Java JavaScript HTML CSS Ant XML Locators
- 6. Selenium Introduction Test tool for web applications Runs in any mainstream browser Supports tests in many languages Selenium(pure HTML, no backend required) Java, C#, Perl, Python, Ruby Record/playback (Selenium IDE) Open Source with corporate backing Lives at selenium.openqa.org
- 7. What is Selenium? Selenium automates browsers. Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.
- 8. Why selenium? Selenium is probably the best option for automated testing of Websites today. It is becoming increasingly popular and it is the first choice of automation testers as well as organizations for automating the testing of Web-based applications for both the GUI as well as the functionality. Selenium can also be used as a unit testing tool for JavaScript
- 9. You can use opensource.Selenium tool selenium IDE is a plugin to firefox to record and playback tests (like WinRunner, QTP). You can then export the recorded test in most language e.g. html, Java , .net , perl , ruby etc. The exported test can be run in any browser and any platform using “selenium remote control”.
- 10. Advantages of Selenium Free! Can test across multiple browsers Mimics actual user experience Ajax / CSS support Use language of choice Large user community Great tools: CubicTest, Grid, HRMES
- 11. Overview of Selenium Components Selenium IDE - Plugin to Firefox to record and play test in firefox and also export tests in different languages. Selenium RC- Allows playing of exported test in different platform/OS. Selenium Grid -Allows to control lots of selenium machines. Selenium Web driver 2.0-Driving a browser natively as a user would either locally or on a remote machine using the Selenium Server it marks a leap forward in terms of browser automation.
- 13. Selenium IDE Easy record and playback. Intelligent field selection will use IDs, names, or XPath as needed. Autocomplete for all common Selenium commands. Walk through tests. Debug and set breakpoints. Save tests as HTML, Ruby scripts, or any other format. Support for Selenium user-extensions.js file. Option to automatically assert the
- 14. Selenium RC Selenium Remote Control (RC) is a server, written in Java, that accepts commands for the browser via HTTP. RC makes it possible to write automated tests for a web application in any programming language, which allows for better integration of Selenium in existing unit test frameworks. To make writing tests easier, Selenium project currently provides client drivers for PHP, Python, Ruby, .NET, Perl and Java. The Java driver can also be used with JavaScript (via the Rhino engine).
- 15. A new instance of selenium RC server is needed to launch html test case - which means that the port should be different for each parallel run. However, for Java/PHP test case only one Selenium RC instance needs to be running continuously.
- 17. Selenium Grid Selenium-Grid allows you run your tests on different machines against different browsers in parallel. That is, running multiple tests at the same time against different machines running different browsers and the operating systems. Essentially, Selenium-Grid support distributed test execution. It allows for running your tests in a distributed test execution environment.
- 18. Generally speaking, there’s two reasons why you might want to use Selenium-Grid. To run your tests against multiple browsers, multiple versions of browser, and browsers running on different operating systems. To reduce the time it takes for the test suite to complete a test pass.
- 20. Selenium Web driver Selenium Web Driver is the successor to Selenium RC. Selenium Web Driver accepts commands (sent in Selenese, or via a Client API) and sends them to a browser. This is implemented through a browser-specific browser driver, which sends commands to a browser, and retrieves results. Most browser drivers actually launch and access a browser application (such as Firefox or Internet Explorer); there is also an HtmlUnit browser
- 21. Unlike in Selenium 1, where the Selenium RC server was necessary to run tests, Selenium Web Driver does not need a special server to execute tests. Instead, the Web Driver directly starts a browser instance and controls it. However, Selenium Grid can be used with Web Driver to execute tests on remote systems.
- 23. Selenium IDE Selenium RC Webdriver Works only on mozilla Works on almost all browsers.Does not work on latest version of firefox/IE Works on latest versions of almost all browsers - Firefox, IE(6,7,8), OPera, Chrome Record and run tool No Record and run No Record and run No server required to start Server is required to start No server required to start Core engine is Javascript based Core engine is Javascript based Interacts natively with browser application Very simple to use. Its a simple and small API Complex and a bit large API as compared to RC Not at all object oriented Less Object orinted API Purely Object oriented API Cannot move mouse with it Cannot move mouse with it Can move mouse cursor Full xpaths have to be appended with 'xapth=' syntax Full xpaths have to be appended with 'xapth=' syntax No need to append 'xpath='
