Tester Guide
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.
Integration Tester Reference
This guide provides the topics to help the Integration tester use the product by using the user interface, commands or scripts. This guide is intended for Integration testers.
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.
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.

  - 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 V8.5, you can convert it to work in V8.6 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.
    - 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 V4, you can use Eclipse to convert the function for use with V5 or later.
    - Converting existing function classes without Eclipse
      You can convert functions that were written for Rational® Integration Tester V4 to work with V5 or later without Eclipse.
  - Working in non-GUI mode
    Many test actions can be completed in non-GUI mode by using the command line, Ant, or REST interfaces.

  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.

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.

About this task

For details on developing the function and generating the plug-in, see Create the plug-ins in Eclipse and Implementing the function class.

To configure the function for use in Rational® Integration Tester, do the following steps:

Procedure

If you did not yet generate the plug-in in the Functions folder of the Rational® Integration Tester project, then copy it there now (for example, if your project is stored under C:\RationalIntegrationTester\Project1, copy the plug-in JAR or plug-ins folder to C:\RationalIntegrationTester\Project1\Functions).
In Rational® Integration Tester, click Tools > Functions > Reload Custom Functions to load all functions in the Functions folder and the plug-ins subfolder.
Optionally, click Tools > Functions > View All Functions to verify that your custom function is loaded.

The Functions dialog displays a list of all the plug-ins that are known to Rational® Integration Tester, sorted alphabetically by function name.

Note: If the new function is not listed, review the steps that were carried out to ensure that nothing was missed.

You can now use the custom function like any other function in Rational® Integration Tester.
