What to do Actions – Manipulates the state of application e.g. click/clickAndWait, type/typeAndWait Accessors – Examines the state of application and stores the results in a variable e.g. storeTitle Assertions – Verifies the state of application and conforms to what is expected. All selenium assertions can be used in 3 modes ‘assert’, ‘verify’ and ‘waitFor’. Element Locators – tells sel. Which HTML element a command refers to Locators could be of id, name, dom, xpath, link or css Patterns – can be used for various reasons. e.g. can be used to specify an expected value Patterns could be of values, exact/reg-ex/glob string Script pane – in detail Overview

- 13. Introduction Overview Selenium Core is a tool to Test Functionality and Browser Compatibility of web applications Runs directly in the browser and lets the user only to run the tests Platform support Browsers – FF 3, FF 2, IE 7, Safari 3, Safari 2, Opera 9, Opera 8 OS – Windows, OS X, Linux, Solaris How ever works on any platform with JavaScript enabled browsers
- 14. Installing Selenium Core 0.8.3 Overview Download Sel. Core from http://selenium-core.openqa.org/download.jsp Make it available from the same web server as the application you want to test If you can’t modify the application’s web server you want to test, then core isn’t the right tool for you ! Open Sel. Test runner as a http page and NOT as a file
- 15. How Selenium core works? Overview Uses JavaScript and Iframes to embed a Test Automation engine in your browser Why I’ve to Install Sel.core on the same place as web server is?
- 16. Exploring Selenium Test Runner 0.8.3 Overview
- 17. Testing using Selenium Core Overview Generate Test Scripts using Selenium IDE Place the Test Suite in Tests folder of Sel. Core Give away the Test suite’s path in Test Runner and click Go Run the Test Suite / Test Cases Analyze the Test Results for its Functionality Analyze the Test Results for its Browser Compatibility
- 18. Overview HTA mode HTA mode works only with IE on windows, can’t use it for testing with any other browsers HTA file is a special type of HTML file, that is allowed to violate the same origin policy You don’t have to install core onto the web server Just open TestRunner.hta file in the Sel. Core installation folder, you’re now free to run your tests against any website
- 19. Selenium Remote Control 0.9.2
- 20. Introduction Overview Selenium Remote Control is a tool to test the functionality and browser compatibility of web applications Test scripts can be generated in programming languages of user choice Platform support Programming Languages - HTML, C#, Java, Perl, PHP, Python and Ruby Browsers – FF 3, FF 2, IE 7, Safari 3, Safari 2, Opera 9, Opera 8 OS – Windows, OS X, Linux, Solaris How ever works on any platform with JavaScript enabled browsers RC is great for testing complex AJAX based web UI under a continuous integration system
- 21. Selenium RC Architecture Overview
- 22. Overview RC client driver reaches out the RC server RC server launches a browser RC server bundles selenium Core and automatically loads into the browser TestRunner in core will now open AUT The Test script starts running How Selenium RC works?
- 23. Installing Selenium RC 0.9.2 Overview Download selenium RC from http://selenium-rc.openqa.org/download.html Install the latest version of JRE and add it to path env. variable check using java –version in the command prompt Install the latest version of PERL Install selenium PERL client driver, run the foll. commands in PERL client driver directory perl makefile.pl – you’ll now find an auto-generated make file nmake install (for windows) – PERL modules will be downloaded from CPAN
- 24. Testing options on Selenium RC Overview Testing without Coding Normal Mode Interactive Mode – for rapid prototyping of tests Proxy Injection Mode – Experimental feature for now Programming the Test using any of the supported Programming Languages
- 25. A Sample Test using RC in Interactive mode Overview Start the server in interactive mode the cmd line - java -jar selenium-server.jar -interactive Launch the browser - cmd=getNewBrowserSession&1=*iexplore&2=http://www.google.com (or) cmd=getNewBrowserSession&1=*firefox&2=http://www.google.com Jot down the session id; say, session id = 260113 Lets do a Google search ! cmd=open&1=http://www.google.com/webhp&sessionId=260113 cmd=type&1=q&2=hello world&sessionId=260113 cmd=click&1=btnG&sessionId=260113 Getting the page’s title cmd=getTitle&sessionId=260113 Wind up - cmd=testComplete&sessionId=260113
- 26. Sample Test run using Selenium RC with PERL script…
- 27. More on RC…. Overview RC circumvents Same origin policy by acting as a client-configured proxy Automatically Launching other browsers cmd=getNewBrowserSession&1=*custom c:\Program Files\Netscape\Netscape\Netscp.exe&2=http://www.google.com – Must manually configure HTTP proxy as ‘localhost:4444’ Running Tests under multi-window - java -jar selenium-server.jar -multiWindow
- 29. Introduction Overview Selenium Grid is a tool that dramatically speeds up end-to-end web testing Transparently distributes your tests on multiple machines, so that tests run on parallel Cuts down time required for running in-browser test suites How Selenium Grid works?
- 30. Installing Selenium Grid 1.0.1 Overview Hub machine Install the latest version of JRE and JDK, check using java -version Install the latest version of ANT Download the binary distribution Add the ANT folder to PATH env. Variable check using ant –version Download the latest Selenium Grid from http://selenium-grid.openqa.org/download.html Transparently distributes your tests on multiple machines, so that tests run on parallel Go to the root of Selenium Grid directory validate the installation – ant sanity-check Remote control machines should have Selenium RCs installed
- 31. Running Tests in Sequence on Firefox on a single machine Overview Launch Hub by using ant launch-hub in Hub machine Check whether that the Hub is running by looking at http://localhost:4444/console Launch RC in a new terminal using ant launch-remote-control in Hub machine Now check http://localhost:4444/console for a running remote control Run demo in sequence using ant run-demo-in-sequence in a new terminal
- 32. Running Tests in Parallel on Firefox on a single machine Overview Launch Hub by using ant launch-hub in Hub machine Check whether that the Hub is running by looking at http://localhost:4444/console Launch RC in a new terminal using ant launch-remote-control in Hub machine Launch 3 more RCs in separate terminals ant -Dport=5556 launch-remote-control, ant -Dport=5557 launch-remote-control, ant -Dport=5558 launch-remote-control Now check http://localhost:4444/console for all four running remote controls Run demo in parallel using ant run-demo-in-parallel in a new terminal
