Extending HCL OneTest™ API functionality by using custom functions
You can add more calculations and operations to tests by using the HCL OneTest™ API custom function class. HCL OneTest API 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.
Configuring an extension element
You can configure an extension element.

- API 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. This guide is intended for API testers.
  - API Testing
    You can use find information about the tasks that you can perform for testing various domains, technologies, or applications.
  - Extending HCL OneTest™ API functionality by using custom functions
    You can add more calculations and operations to tests by using the HCL OneTest™ API custom function class. HCL OneTest API 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
      HCL OneTest™ API recognizes functions that are packaged as Eclipse plug-ins. You can create a plug-in and register it as a function in HCL OneTest API from an Eclipse IDE.
    - Implementing the function class
      If you have a function that is written for HCL OneTest™ API 8.5, you can convert it to work in HCL OneTest API 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 HCL OneTest™ API to pick it up (similar to generating a JAR).
      - Adding external libraries
        You can add external libraries.
    - Configuring the function in HCL OneTest™ API
      After the function is developed and a plug-in is generated, you should communicate that to HCL OneTest™ API 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 HCL OneTest™ API 4, you can use Eclipse to convert the function for use with HCL OneTest API 5 or later.
    - Converting existing function classes without Eclipse
      You can convert functions that were written for HCL OneTest™ API 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 - 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 API Testers.

Configuring an extension element

You can configure an extension element.

About this task

To configure an extension element, perform the following steps:

Procedure

Complete the fields in the Extension Element Details as described in the following table:


Field	Value
name	The name of the function. For example, `formatDate`.
displayName	The name under which the function is displayed in the Functions menu. For example, `Format Date`. To place the function under a specific submenu, prefix the display name with the name of the submenu and a forward slash / character. For example, `Custom/Format Date` places the function under a Custom submenu. Any number of submenus is permitted by using the same naming format.
syntax	The syntax of the function. For example, `formatDate(date, inputFormat [, outputFormat])]`.
functionClass	The class that performs the work of the function. This class must be a fully qualified class name that extends from com.ghc.ghTester.expressions.Function. With Eclipse, you can enter the name manually or search for it using the Browse button.
minParameters	The minimum number of parameters to pass to the function. For example, `2`.
maxParameters	The maximum number of parameters to pass to the function. For example, `3`. Entering `-1`, indicates that there is no maximum and any number of arguments that is greater than or equal to minParameters is accepted.
