HP Unified Functional Testing Professional
HP Unified Functional Testing (UFT) software, formerly known as HP Quick Test Professional (QTP),<ref>http://www.automationrepository.com/2012/12/hp-unified-functional-testing-uft-11-5-new-features</ref> provides functional and regression test automation for software applications and environments.<ref>http://www8.hp.com/us/en/software-solutions/application-lifecycle-management-application-test-software/index.html?zn=bto&cp=1-11-127-24^1352_4000_1__</ref> HP Unified Functional Testing can be used for enterprise quality assurance.<ref>http://www.learnqtp.com/qtp-quality-center-test-director-guide/</ref> HP Unified Functional Testing is a test automation tool originally developed by Mercury Interactive and later acquired by Hewlett Packard.<ref> http://www.devbistro.com/articles/Testing/Mercury-QuickTest-Professional-Evaluation</ref> HP Unified Functional Testing 11.5 combined HP QuickTest Professional and HP Service Test into a single software package,<ref> http://selftechy.com/2013/10/07/hp-uft-11-50-unified-functional-testing</ref> which is currently available from the HP Software Division. The integrated HP Unified Functional Testing software allows developers to test from a single console all three layers of a program’s operations: the interface, the service layer and the database layer.<ref>http://www.computerworld.com/article/2493313/data-center/hp-simplifies-automated-software-testing-suite.html</ref>
Background
Test automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions.<ref>The Testing Network: An Integral Approach to Test Activities in Large p413</ref> Test Automation is a development discipline as it uses scripting languages to instruct the tool how to interact with your application. As such careful consideration needs to be paid to
- Exception handling for bugs that occur during testing cycles(i.e, unexpected error messages during a test run).
- How the tool synchronizes with your application(e.g. if there are slow response times from your environment)
- The level of maintenance required to keep the tests up to date with changes in the application GUI(i.e, new buttons, data fields, custom controls etc)
Any test automation framework is a set of assumptions, concepts and tools that provide support for automating the major activities in the testing process. The main advantage of a framework is
- Increased Productivity
- Easy and Reduced maintenance effort
- Consistent automation development across projects
- Process driven than person driven approach
- Controlled maintenance of automation artifacts
There is a range of automation testing tools available. Some of them are licensed and few others are open sourced. QTP, Cucumber, Capybara and other tools<ref>http://en.wikipedia.org/wiki/List_of_web_testing_tools</ref>
Description
Although HP UFT is usually used for UI based Test Case Automation, it can also automate some non-UI based test cases like database testing, webservice testing and file based operations. It offers a graphical user interface, keyboard support, multiple testing views, and scripting language. <ref>http://www.softwaretestinghelp.com/qtp-quicktest-professional-tutorial-1/</ref>
Data Driven Testing
HP Unified Functional Testing supports data-driven testing. For example, data can be output to a data table for reuse elsewhere. Data-driven testing is implemented as a Microsoft Excel workbook that can be accessed from HP Unified Functional Testing. HP Unified Functional Testing has two types of data tables: the Global data sheet and Action (local) data sheets. The test steps can read data from these data tables in order to drive variable data into the application under test, and verify the expected result.<ref>http://www.qtp10.com/2009/07/using-global-and-action-data-sheets-in.html</ref>
Views
HP Unified Functional Testing provides two views—and ways to modify—a test script: Keyword View and Expert View. These views enable HP Unified Functional Testing to act as an Integrated Development Environment (IDE) for the test, and HP Unified Functional Testing includes many standard IDE features, such as breakpoints to pause a test at predetermined places.
Keyword view
Keyword View lets users create and view the steps of a test in a modular, table format. In Keyword View, users can also view properties for items such as checkpoints, output values, and actions, use conditional and loop statements, and insert breakpoints to assist in debugging a test.
Expert View
Expert view displays test code using VBScript. Designed for more advanced users, users can edit all test actions except for the root Global action, and changes are synchronized with the Keyword View.[17]
Scripting
HP UFT's VBScript allows for classes, but not other object oriented properties such as inheritance and polymorphism. It also lacks a debugger, however UFT has a debugger provided by HP. Some Windows script (WScript,WSH,WMI) & VB.Net code can be used in a script in the expert view <ref>https://h20546.www2.hp.com/main/training/course_details.cfm?Course=00008165&sitepick=US</ref>
Exception handling
Application crashes, Unexpected events and errors during a run session can disrupt the run session and distort results. This is a problem particularly when tests run unattended—the test pauses until one performs the operation needed to recover. To handle such situations, Error and Exception Handling is must while developing script or Automation Framework. Error and Exception handling in HP UFT can be done by the following ways:
- Conditional Statement
- On Error statement
- Recovery Scenarios
Life Cycle
Comparison to other tools
Tools such as Cucumber and Capybara run tests from the perspective of the user. Cucumber converts user stories into tests and Capybara simulates a user or web browser. Unified Functional Testing is used by programmers to preform specific test cases they code themselves.<ref>Engineering Long Lasting Software p136</ref>
Capybara is a tool that interacts with a website the way a human would (like visiting a url, clicking a link, typing text into a
form and submitting it). It is used to emulate a user's flow through a website. With Capybara you can write something like this:
describe "the signup process", :type => :feature do before :each do User.make(:email => 'user@example.com', :password => 'caplin') end it "signs me in" do visit '/sessions/new' within("#session") do fill_in 'Login', :with => 'user@example.com' fill_in 'Password', :with => 'password' end click_link 'Sign in' page.should have_content 'Success' end end
Cucumber is a tool to write human-readable tests that are mapped into code. With it, you can rewrite the above example like this:<ref>http://stackoverflow.com/questions/15004918/cucumber-vs-capybara</ref>
Scenario: Signup process Given a user exists with email "user@example.com" and password "caplin" When I try to login with "user@example.com" and "caplin" Then I should be logged in successfully
Selenium is a tool for automating web applications for testing purposes.

Possible through Rake, Ant, Maven and JUnit output |
Disadvantages
Unified Functional Testing is developed mainly for Windows based systems and it relies on outdated Windows tools like VBXScript. Tests can not be run outside of the UFT environment nor are they compatible with all browser types.<ref>http://www8.hp.com/us/en/software-solutions/unified-functional-testing-automated-testing/demos-documents.html#!&pd1=1</ref>
