Testing of Web Applications

• 3 main areas of testing
• Content Testing
• Security Testing
• Functional Testing
• Each area has testing tools tailor made for it.

Content Testing

• Testing of the visible part of the web site
• Testing Tools
• W3C Consortium Free Online Tools
• Markup Validator
• Link Checker
• CSS Validator
• and more

Security Testing

• Testing for security threats within the web
  application
• Testing tools
• OWASP open source testing tools
• Commercial tools
• Acunetix
• SecurityInnovation
• SpyDynamics

Functional Testing

• Testing of the business logic of the web
  application
• Testing tools
• Open source tools
• Selenium
• MaxQ
• Commercial tools
• iMacros
• WAPT

Selenium

• Pros
• Executes directly in Web Browser
• Platform Browser independent
• Supports a wide range of programming languages
• Cons
• Not capable of testing Java Applets

Testing of Java Applets

• Tools Available
• Conventional Java GUI testing tools
• Are not a web application testing tool
• Treats a Java Applet as a conventional GUI
  application
• iMacros
• Makes use of image recognition technology to
  capture and playback events
• Can be used to test different types of media
  files (Flash, Shockwave, ActiveX, ) not Java
  Applet specific
• It is a commercial tool ( 699.00 per license)

Conclusion (Testing of Web Applications)

• There are tools to test the different areas of
  Web Applications
• However there isnt a tool tailor made
  specifically to test Java Applets
• The aim of this FYP is to develop a test
  automation tool for Java Applets - TATJA

TATJA

• A browser and platform independent tool to test
  Java Applets
• Applets are tested in their actual running
  environment
• A record/playback testing tool
• Supports regression testing
• Does not makes used of any other third party
  scripting languages
• Is a flexible tool

TATJA Overview2/3

• TATJA is in itself a Java Applet
• The Applet to be tested is loaded within TATJA
• TATJA wraps within it the Applet to be tested
• TATJA can gain access to each component of the
  Applet to be tested
• TATJA can be operated in two modes
• Record Mode
• Playback Mode

TATJA Overview3/3

• Flexibility
• The actions that can be performed on the Applets
  components are defined by the user through an XML
  document (TatjaML)
• Reason
• To make the tool compatible with all possible
  Java Swing component

TATJA Basic Building Blocks

• User Interface
• Applet Wrapper
• Recorder Handler
• Playback Handler
• Regression Test Runner
• Component Identification Mechanism

TATJA in Record Mode1/2

• The user records the test actions on the
  components of the Applet to be tested
• Test actions includes
• Button clicks
• Text input to text fields
• Mouse clicks
• The test actions are converted into Java code and
  stored in Java classes.
• 1 Test Case gt 1 Java Method

TATJA in Record Mode2/2

• Block Diagram

• When test cases are recorded, they can be
  edited/enhanced by the user manually

TATJA 7/12

TATJA in Playback Mode

• The User loads the Java Class with the test cases
• Selects the test method and executes it
• Block Diagram

Regression Tests in TATJA1/2

• The Applet to be tested is wrapped within another
  Applet
• A Java method that invokes a selection of test
  cases written within this Applet wrapper
• An HTML document that embeds the Applet to be
  tested is generated
• A JavaScript call to the Java method listed in
  the second bullet
• By loading the generated HTML page in a browser,
  the test cases are executed automatically

The TatjaML Document1/2

• Has a list of all the actions that can be
  performed on each component
• An action can be
• A method call on the component
• An event
• Each action includes the information that is
  needed by TATJA to dynamically perform it
• Which method to invoke
• Which event listener to create
• Which event Object to pass
• and more

Conclusions

• TATJA was tested with existing Java Applets of
  different types on different browsers
• The desired functionality was obtained and the
  testing tool gave the expected results
• All objectives set for this project were
  successfully achieved
