Plenty of Testing framework exist for Java. JUnit has been the de facto standard for unit testing. However, other frameworks such as TestNG, JTIGER have been built to address various faults and deficiencies with JUnit.  Our primary objective is to compare the various testing frameworks that exist for object oriented languages based on the primary purpose of the framework, strength, platforms that are supported by them, etc and thus help in choosing the best testing framework that fits in a particular suitable environment.

= Welcome to the Expertiza project! =


TestNG is a testing framework which can help to meet a broad range of testing such as unit testing, integration testing, functional testing, end-to -end testing.
The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.


To write a TESTNG test, we need to:
== Short Powerpoint introductions ==
Write the business logic of the test, and insert the TestNG annotations in them.

Add the information about our test (such as: the class name, the groups we wish to run, etc) in a testing.xml file or in build.xml.  
*My [http://research.csc.ncsu.edu/efg/expertiza/presentations/Purdue_TLT_2009.ppt plenary talk] at the Purdue TLT Conference on April 22, 2009

TestNG supports data driven testing
*You can walk through a [http://research.csc.ncsu.edu/efg/expertiza/presentations/Expertiza%20in%20Action.ppt virtual demo] of the system.


TestNG is invoked in several different ways:

It is possible to group the test methods of TestNG.  We can declare methods that belong to these groups and specify groups that contain other groups. It is very flexible as it can help in choosing one set of regular expression and excluding the other sets. This splits the various test groups and there is no need to recompile again if we want to run two different tests back to back.

== Cactus ==
 
 
(source : http://jakarta.apache.org/cactus/index.html)
Cactus is a test framework for testing server-side java code such as Servlets, EJB, etc. It extends J Unit.
Cactus implements an in-container strategy which means that tests are executed inside the container.
The Cactus testing unit can be viewed as a system that consists of the following components:
Cactus Framework:  This provides the API to write Cactus tests.
Cactus Integration Modules: They are front ends and frameworks that provide easy ways of using the Cactus Framework. Eg: Eclipse plugin
Cactus Samples: They demonstrate how to write Cactus tests and how to use a few Integration Modules.
 
A useful testing framework provided by Cactus is  integration unit testing( type 2).  The tests written for this framework will exercise the interactions with the container. Cactus also provides other frameworks such as code logic unit testing (type 1) ,functional unit testing( type 3).
 
Cactus was developed to fit Type 2 but also to be a very good compromise for types 1 and 3, with the idea that it is much easier to have to write tests for a single framework than for several. It is believed that Cactus provides a middle ground that provides a high confidence that your code will run when deployed .

CppUnit passes most of the above tests , except for the first point and thus needs a lot of code typing.
Boost.Test isn’t exclusively a unit-testing framework, and is not X Unit based.
 
Out of the above three , cxxUnit turns out to be a favourite.
 
It comes close to the requirements of an ideal framework by leveraging the power of an external scripting language. It provides some nifty advanced features and great assert functionality. It does require the use of a scripting language as part of the build process, so those uncomfortable with that requirement, might want to look at one of the other two frameworks.
 
For work restricted to the PC,  where modifying the framework is not required Boost.Test could  be a very good choice.
CppUnit , which has come a long way in years is a solid, complete framework  The major drawbacks are the relative verbosity for adding new tests and fixtures.

Welcome to the Expertiza project!

The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.

Short Powerpoint introductions

  • We invite you to view the original rationale for the system.
  • You can walk through a virtual demo of the system.

Papers

  • A prose rendition of the rationale was published in Innovate in 2007. (To view it, you need to register, and you will receive e-mail each time a new issue of this very interesting and useful journal is published.)
  • Other papers on Expertiza can be found here.

Video presentations

Documentation

  • An instructor manual, explaining how to create an deploy an assignment in Expertiza.
  • An instructor video, slightly dated, showing how to create and deploy an assignment
  • A design document for the application.
  • A guide for Creating_Custom_Rubric
