2 Abstract Testing is a repeated task in software development. Every time source code are changed or before each release, testing should be repeated to make sure no error. To manually test costs man power, time and money. In addition, repeating tests might cause boredom for testers and human errors are unavoided so automated test is indeed necessary. Also, GUI 1 automated test is difficult because it breaks easily especial in the first stage of project. I am tasked to provide an automated test for SharePoint web. It is challenging to automate this kind of web because the way JavaScripts are used. Maintain test script that works with changing UI 2 will mostly depending on a chosen automated testing tool. If selecting a tool that locate object by its identify, the work is simpler because it is independent from GUI. Moreover, this web is made from SharePoint 2007 so it just works well on Internet Explorer. In ELCA Company, the developer has to do the tests and time for tests is limited so the language of test script should be same with them. So the chosen web automated test tool must meet that requirements. I use WatiN to automate the tests. It is a free tool but has many good features: automates all major HTML elements, find elements by multiple attributes, supports AJAX, frames and iframes, popup dialogs, etc. In addition, it is easy to use WatiN to create test script with C# language without learning new language. I have completed my assignments using WatiN and found a bigger challenge in this project on how to automate SharePoint context menus and the solution is left to my future work. 1 Graphical User Interface 2 User Interface

7 Acknowledgements I would like to thank Jean-Paul Tschumi - General Director of ELCA Information Technology Limited Company in Vietnam for giving me a chance to do my internship at ELCA. I would like to thank my supervisors, Le Do Anh Phong - project leader of the project that I am tasked to provide automated test and Nguyen Huu Hung - group leader for all their guidance and support. 5

8 Chapter 1 Introduction 1.1 Context My internship at ELCA Company is a requirement for completing my Master degree of Software Engineering at the Pôles Universitaires Français 1, Ho Chi Minh City. My internship lasted 4 months from the beginning of July Software verification is one of the challenging and interesting topics that I have chosen to do with ELCA. And I was tasked to provide automated test for the web. 1.2 ELCA Company ELCA 2 is an IT Services Company of Switzerland. It is established in 1968 and present in Vietnam since It supplies services in software development, system integration and business consulting. ELCA Vietnam is the group s first offshore software development center. Its main mission is to support the mother company (the Contractor) serving clients throughout Europe and the world. Every year, ELCA has more than 200 projects in many domains such as Banking, Insurance, Healthcare, Government, Transportation and Ticketing. It has achieved CMMI 3 standards. 1.3 Microsoft SharePoint SharePoint 4 is a family of software products developed by Microsoft for collaboration, file sharing and web publishing. Microsoft SharePoint is a powerful software package that help people to work together. Using SharePoint, people can set up Web sites to share information with others, manage documents, publish reports and eventually helps everyone makes better decisions

9 1.4 My tasks ELCA Company is building an extranet for an international organization to allow controlled access to its remote clients from outside under a collaborative platform. ELCA is responsible for delivering softwares and also build new services, functions and add-ons to released products per clients request while maintaining current system, making updates and corrective releases to previous versions. Every time new services are developed, regression test must be done to detect errors and ensure the web still works with the new development. I m tasked to provide automated tests for the web focusing on regression tests and functional tests. The task is broken down as followed: Study automated test Study the business of project Select an appropriate tool to use for automated test Create a test suite including all test requirements Maintain an dynamic test suite which reacts to source code changes Detect and solve problems generated when automated test is applied to SharePoint web

10 Chapter 2 Automated test 2.1 Term in testing Manual testing: is a part of software testing that testers run the test and input parameters manually. Regression testing: is the testing of a previously tested programs to ensure original functions of the program are not compromised when producing new modifications. Functional testing: is a test to make sure software is meeting requirements and error free. 2.2 Automated test overview Definition of automated test Test automation 1 is the process of using certain software for the purpose of controlling the implementation and execution of tests, comparing the results or outcomes of the same to those which were predicted or foreseen Pros and cons of automated test Automated test has many advantages and disadvantages 2. Pros: Reusability: Test suite can be used on different software versions or on different support environments

11 Repeatability: Repeat tests every time source code changes to detect regression errors more quickly without human errors Cons: Better quality: High cost: Increase the test frequency to ensure quality Improve test coverage with minimum resources Save time for manual testers to do other tests Improve reliability and consistency of the testing process as well as increase confidence in software quality Select an appropriate tool and learning curve time Hard to write an easily maintainable test suite which is suitable to all source code changes Maintain test script is costly if you just record and playback the test because it easily breaks when UI changes 2.3 What test case should be automated? It is important to choose what test cases should be automated [1]. Test cases for automation are: Tests that run frequently: Tests run on many different environments - all support operating systems and hardware configurations. Functions are used frequently. Tests that consume a lot of time when do manually and require a lot of input data. 2.4 How to create automated tests which are independent of UI changes Create automated tests which are resistant to UI changes [1] are the most important thing to cut down the maintenance cost. To do this, it depends on your chosen tool and the way you write your code. There are a lot of ways to locate an object on the screen by relying on all its attributes but the best way is to rely on its identity. With that way, when the UI changes, the tests are still resistant.

12 Create a unique name for each control when you develop the project Choose an automated testing tool which relies on that unique name to find the control 2.5 Web automated test tool selection I am tasked to select one of the 4 following tools that the project leader suggested: Canoo Web Test 3 Selenium 4 Squish 5 WatiN 6 This project is made from SharePoint 2007 so it just works best on Windows Server and Internet Explorer 7 and 8. Base on its support environment, the web automated test tool must have the following criteria (see table 2.1). I selected WatiN for the following reasons: Meet all requirements of tool selection It is free C# is the test script language that the ELCA developers are using. In ELCA, developer does the test so it is easy for them to write test script without learning new language. In SharePoint, identify of control is a sequence of character that is automatically generated. It has two parts: the head of the sequence is not the same in every run. The end of the sequence is the name of the control so it is difficult to find the control with whole sequence of identify. We just find the control by using the end of the sequence. And WatiN has method EndW iths(string) that is suitable to locate the control in this case (see example in the next page)

13 Example: ID of text field User name: Figure 2.1: Login Screen Find that control by simple way: m_ie. TextField ( Find. ById ( item => item. EndWith (" UserName "))). TypeText (" loginname "); WatiN Squish Selenium Canoo Web Test Browser: IE 7 Yes Yes Yes No and 8 Language of C# JavaScript, Selenese(its XML test script Python, Perl, Tcl own scripting language) Frame/Iframe Yes Yes Yes Don t know support Ajax support Yes Yes Yes (but restricted) Don t know JavaScript Yes Yes Yes Yes Recorder Yes (use external Yes Yes (just record Yes (use external tool WatiN Test Recorder) on FireFox) tool, just record on FireFox) Wait for page Yes Yes Yes (but not Support only fully loads completed) HTML standard Price Free Commercial Free Free Table 2.1: Tool comparison

14 Chapter 3 Implementation 3.1 Class diagram of test scenarios In this project, I am tasked to provide automated test for a part of project which is NocNetTest. Because of confidentiality, ELCA requires me not to talk about their customers so all pictures or screens in this report are not same with the real project. And the following picture is a part of class diagram of test. Figure 3.1: Class diagram of test scenarios BaseTest class: Contents methods SetU p(), T eardown() and all methods are used commonly for all test parts. SetUp() is used to instantiate objects needed to run test and 12

15 T eardown() is used to clean up and dispose of objects after running test. Each test scenarios begins with SetU p() and finishes with T eardown(). NocNetTest class: Contents all test scenarios of my part. 3.2 The tools These are tools that I used to provide automated test for the web: Microsoft Visual Studio 2008 Standard Edition 1 WatiN 2.0 WatiN Test Recorder NUnit Microsoft Visual Studio and WatiN were used to create test suite. If you are new in WatiN, you should have WatiN Test Recorder to help create test script easily by its record function. Then, use NUnit to execute the test suite. 3.3 How to create and run test scripts To create test scripts, the following steps must be followed: 1. Create a project in Microsoft Visual Studio and in Reference of the project, add nunit.framework of NUnit and WatiN.Core, WatiN.Core.UnitTests of WatiN (see figure 3.2). Then, create test script normally. 2. Build project into an.dll file or.exe file. 3. Launch NUnit and open above.dll/.exe file. Click Run button to execute tests, if results of all tests are same with the expected results, the progress bar is colored green, and red if there are any failures (see figure 3.3) Figure 3.2: Add reference

16 Figure 3.3: Results of running test suite successfully 3.4 Problems and solutions during automated test Ensure the same starting point for every run We must prepare all predefined test data and use same predefined test data to begin the tests. After running the tests, we must come back to initial state of the web to run the tests again. Solution 1: Backup and restore database before and after running tests: require the testers know how to backup and restore database. Solution 2: easier than solution 2 Use snapshot function of VMware 4 application. - Prepare test environment and then take a snapshot of VMware. - Run tests. - Revert to snapshot which has just been taken to have same starting point for next test. 4

17 3.4.2 How to create easy maintenance test data to automatically fill in create/edit forms I used hard coded test data with a sequence number as suffixes. Each time a test is executed, that sequence number is automatically increased one unit. For example, when I test register user function, I use login name as usersquencenumber. When the test is first run, login name will be user1, and user2 for the second run, etc. Doing this way, I don t need to back up and restore database before and after running tests because the test data are always unique. Problem, it is difficult to check data that are existed in the web after creating new or editing an object. In particular, we can t determine which page that object is in when the data are growing and are contained in many pages. Solution: I use a free test data generator tool at web site to generate test data in an Excel sheet. All input data for each specific group of test cases is organized like a table. We can read data from Excel sheet like reading a table in database and it is easy to edit or modify data in Excel sheet. For example: test data for registering users: Figure 3.4: Test data for registering users Can t add a web part into web page Web part 5 is an integrated set of controls that end users can add into a web page.it enable end users to modify the content, appearance, and behavior of Web pages directly in a browser. Solution: Consider Web part dialog as an HtmlDialog, add a AlertAndConfirmDialogHandler into browser m_iexplorer to control that Web part dialog. This is code for adding a web part into web page: // add web part into page AlertAndConfirmDialogHandler webparthandler = new AlertAndConfirmDialogHandler (); HtmlDialog webpartdialog ; // add a AlertAndConfirmDialogHandler to browser before opening web part dialog m_ iexplorer. AddDialogHandler ( webparthandler ); 5

18 Figure 3.5: Web part dialog // open web part dialog m_iexplorer. Link ( Find. ByTitle (" Add a Web Part ( opens in new window )")). ClickNoWait (); webpartdialog = m_ iexplorer. HtmlDialog ( Find. ByTitle (" Add Web Parts ")); // select a web part that you want to add into web page webpartdialog. CheckBox ( Find. ByTitle ( item => item. Contains ( pageinformation [" WebPart "]. ToString ()))). Checked = true ; webpartdialog. Button ( Find. ById ( item => item. EndsWith (" btnok "))). Click (); // close web part dialog webpartdialog. Close (); Can t select item in select column in grid view In grid view, can t select item that we want because it has only one same text attribute for all items in column that has select link. So we can t distinguish items. Solution: Execute JavaScript on the page to replace "Select" by corresponding name in Name column and now it is easy to select whatever contact name that you need.

19 Figure 3.6: Grid view of contacts list before and after executing JavaScript This is the JavaScript code: // run script to replace " Select " by the name in next column m_iexplorer. RunScript var table = $( table.ms - listviewtable ) [0]; for ( var i = 1; i < table. rows. length ;i ++) { var select = table. rows [i]. cells [0]. firstchild ; if ( select!= null ){ var text = table. rows [i]. cells [1]. firstchild. innerhtml ; select. innerhtml = text ; } }") ; // select contact name that you want m_iexplorer. Link ( Find. ByText ( contactname )). Click (); Can t record dynamic element SharePoint web has a lot of context menus that are made from JavaScript and automatically generated with tag < ie : menuitem... >< /ie : menuitem >. It is not the standard HTML tag so the tool doesn t understand these tags. Example: Source code of Create Page menu item <ie: menuitem id =" ctl00_placeholdermainnavigation_siteactionsmenumain_ctl00_wsacreatepage " type =" option " iconsrc ="/ images / crtpage. gif " onmenuclick =" window. location = / CreatePage. aspx ;" text =" Create Page " description =" Create a page in this site." menugroupid ="100" > </ie: menuitem >

20 Figure 3.7: SharePoint context menus Solution: There is no good solution for this challenge till now. I try to find many ways to automate the menus but they almost don t work. With the following code, WatiN tool finds the Create Page menu item and clicks on it but the browser doesn t go to URL of that menu item: // open context menu Site Actions m_iexplorer. Link ( Find. ById ( item => item. EndsWith (" SiteActionsMenu "))). Click (); // find Create Page menu item and click on it m_iexplorer. TableCell ( Find. ById ( item => item. EndsWith (" CreatePage "))). Click (); In order to continue my works, I temporarily work around by going directly to URL of corresponding menu item. // go directly to URL of Create Page menu item m_ iexplorer. GoTo (" replace by url of Create Page ");

21 Chapter 4 Results and future works 4.1 Results I have finished all my tasks. This internship gives me a lot of knowledge about testing. Create test suite includes all requirement test cases. Project manager uses test suite weekly for regression test and functional test before each delivery. 4.2 Future works There is a challenge in section that has not had good solution yet. In the future, find the appropriate solution for this challenge. 19
