Before organizing your extension,
note the restrictions and guidelines provided in this topic.
Restrictions
The following restrictions apply to plug-ins:
- The execution portion of the plug-in must be deployed to an agent.
You cannot assume that the Software Development Workbench is available.
- The execution portion of the plug-in code cannot depend on any
workbench code.
- The execution portion of the code cannot depend on the workspace
because none is available on the agent.
For best results, minimize the amount of code that is deployed
to the agent for execution.
Guidelines for naming plug-ins
Most base Rational® Performance
Tester plug-ins follow this naming convention:
<prefix>.<component>[.subcomponent].<protocol>
where:
- prefix: The prefix com.ibm.rational.test.lt is
used for all load-test-specific Rational Performance Tester plug-ins.
- component: One of the extension components:testgen, datacorrelation, testeditor, codegen, execution, or models.
- subcomponent: Some plug-ins contain subcomponents (for
example, execution.ui contains the UI portion of execution),
or they might have separate code based on their use in a different
component (for example, datacorrelation.testgen and datacorrelation.execution).
- protocol: For example, http, or sap.
(Some plug-ins use core for the base plug-in.)
Using these conventions, the extension can have the following plug-ins:
- com.ibm.rational.test.lt.recorder.protocol
- com.ibm.rational.test.lt.testgen.protocol
- com.ibm.rational.test.lt.models.protocol
- com.ibm.rational.test.lt.testeditor.protocol
- com.ibm.rational.test.lt.sdksamples.datacorrelation.testgen.protocol
- com.ibm.rational.test.lt.sdksamples.datacorrelation.execution.protocol
- com.ibm.rational.test.lt.codegen.protocol
- com.ibm.rational.test.lt.execution.protocol
- com.ibm.rational.test.lt.execution.results.protocol
Alternatively, you can divide the code into two plug-ins, one for
the workbench and one for execution. This has the advantage of deploying
fewer plug-ins. For an example, refer to the Siebel extension to Performance
Tester.
Using this method, you would have the following two plug-ins:
- com.ibm.rational.test.lt.protocol
- com.ibm.rational.test.lt.protocol.execution
Within these plug-ins, you can either arrange the components in
one of two ways:
- As separate source folders
- As separate packages within a single source folder
