Introduction:
The Basic Architecture of Functional Testing Tool
The basic architecture of
Functional Testing tool is described below. Some tools provide less and some
provide more than that mentioned here.
Test Script Definition: In this process, an interaction with the application to
be tested is recorded. The record defines a test script as output. This test
script can be edited using the integrated script editor.
Parameterization of Data Value: For
data-driven tests, the functional tool provides data access capabilities that
help to select the data source accurately. Control points can be defined on the
graphical objects or on data with the tool. This helps to analyze the test
results.
Automated Test Execution: The test cases are executed reproducing the recorded
user interactions. Data driven tests are executed based on the data access
provided during the test definition phase.
Reports on Test Result: When the test execution is finished, the test results
are compared to the reference points based on the control points set during
test definition. Accurate results can be obtained from each comparison.
Functional
Testing – Tools
-
SoapUI: It is an open source cross platform functional testing tool that creates and executes automated functional,
regression, compliance and load tests. All the standard protocols are supported
by SoapUI.
-
WatiN: It is a testing tool that makes testing possible for
web applications in .Net framework.
-
HTTP
Recorder: It is a browser independent testing tool. It allows us
to record functional interactions with websites and produce scripts for
automated playback.
-
Watir: It automates web browsers similar to user interactions.
It uses open source Ruby Library files.
-
Canoo Web Test: It is also an open source
testing tool for automated testing of web applications.
-
WebInject: It is a free automated testing
tool which enables testing of web applications and web services. It can be used
on HTTP interfaces to test individual system components.
-
Solex: Built in as a plugin for Eclipse IDE, it is a free open
source testing tool for web applications.
-
Selenium: It is used to automate web applications for testing
purposes. Selenium WebDriver can be used to create browser based tests for
regression testing. Selenium IDE can be used to create bug reproduction
scripts. It can also be used to create scripts for exploratory testing.
-
HP UFT – HP's Unified Functional Testing
is an automated functional testing tool. It integrates the main features of Quick
Test Pro(QTP), WinRunner and HP Service Test. HP UFT carries out automated
execution of functional tests and thus helps in increasing the speed and cost
effectiveness of the software development and delivery. UFT is very helpful for
performing Regression tests.
-
HP LeanFT: The agile methodology of
software development has called for introduction of test processes early into
the software development life cycle. HP's LeanFT, released on 2nd
June 2015, is an automated functional testing tool that provides a robust
solution to this approach of continuous testing and integration. It
enables coding in familiar scripting languages. It combines the best features
by morphing Selenium with the key functionalities in UFT.
Conclusion
Without
test tools and test automations, functional testing will need to be
accomplished manually by users logging in and performing the tasks in a
business process. To some extent, this seems to be effective. But for an
extensive software application it is not an economical solution. Using
automation tools for functional testing, test scripts can be recorded and used
repeatedly. Thus Functional Testing tools help to eliminate the need for manual
tests hence reducing the risk of errors.
