This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing.

Extending Rational® Integration Tester functionality by using custom functions
You can add more calculations and operations to tests by using the Rational® Integration Tester custom function class. Rational Integration Tester custom function is a Java™ class that extends the com.ghc.ghTester.expressions function.
Exposing the function
You can use your own function with the function extension that consists of a number of attributes that describe the function (for example, name) and the class that implements the function.
Creating an extension
You can create an extension in the plug-ins manifest.

  This guide describes the tasks that you can perform for testing various domains, technologies, and applications. To enable testing, you must configure and enable the environment for testing. This guide is intended for Integration testers.
  - Integration Testing
    You can use find information about the tasks that you can perform for testing various domains, technologies, or applications.
  - Extending Rational® Integration Tester functionality by using custom functions
    You can add more calculations and operations to tests by using the Rational® Integration Tester custom function class. Rational Integration Tester custom function is a Java™ class that extends the com.ghc.ghTester.expressions function.
    - The formatDate example for a custom function
      You can learn about creating a custom function by using an example. The example shows how to build a function, called formatDate, that parses a string-based date representation and returns it in an alternative format.
    - Create the plug-ins in Eclipse
      Rational® Integration Tester recognizes functions that are packaged as Eclipse plug-ins. You can create a plug-in and register it as a function in Rational Integration Tester from an Eclipse IDE.
    - Implementing the function class
      If you have a function that is written for Rational® Integration Tester 8.5, you can convert it to work in Rational Integration Tester 8.6 or later.
    - Exposing the function
      You can use your own function with the function extension that consists of a number of attributes that describe the function (for example, name) and the class that implements the function.
      - Creating an extension
        You can create an extension in the plug-ins manifest.
      - Configuring an extension element
        You can configure an extension element.
      - Generating the plug-in
        Once the plug-in and class are created, they must be packaged. The plug-in must be generated to enable Rational® Integration Tester to pick it up (similar to generating a JAR).
      - Adding external libraries
        You can add external libraries.
    - Configuring the function in Rational® Integration Tester
      After the function is developed and a plug-in is generated, you should communicate that to Rational® Integration Tester by configuring the function.
    - Creating a function plug-in without Eclipse
      You can use Eclipse IDE to easily create the plug-ins. Alternatively, you can build a function by using the Sun Java™ 6 SDK.
    - Converting existing function classes with Eclipse
      If you have an existing function that is written for Rational® Integration Tester 4, you can use Eclipse to convert the function for use with Rational Integration Tester 5 or later.
    - Converting existing function classes without Eclipse
      You can convert functions that were written for Rational® Integration Tester 4 to work with 5 or later, without Eclipse.
  - Working in non-GUI mode
    You can use the tools and executable files that are provided along with the product software. You can use these tools to perform different test actions in a non-GUI mode.
- Tester Guide - Performance Testing
  Typically, a user with the Integration Tester role is also responsible for performance testing. This guide lists all such topics.
- Tester Guide - Service Virtualization
  This guide describes the tasks that you can perform for using virtual services or stubs to simulate parts of an environment if the real services are not yet available or because they are difficult or expensive to use. This guide is intended for Integration Testers.

Creating an extension

You can create an extension in the plug-ins manifest.

About this task

Procedure

Open the plug-ins manifest by double-clicking com.samples.functions.dateformat > META-INF > MANIFEST.MF.
The file is opened in an editor with a number of tabs along the bottom.
Select the Extensions tab and click Add.
Select com.ghc.ghTester.functions in the New Extension dialog.

Note: If the extension does not appear in the list, the dependency to Rational® Integration Tester Functions are not set up correctly.
Click Finish.
An extension and an element are added to the list of extensions.
