Rational® Performance Tester
Test Author Guide
This guide describes how to create test scripts in Rational® Performance Tester and enhances tests by applying different test elements such as dataset, variables, and verification points. This guide is intended for testers.
Creating tests
To create a test, you record representative interactions with an application.
Recording service tests
When you record a test, the test creation wizard records your interactions with the service, generates a test from the recording, and opens the test for editing. You can record a test session by invoking service calls with the generic service client or by using an existing client. You can also create a service test manually or from a Business Process Execution Language (BPEL) model.
Configuring the environment for SOAP security
SOAP security profiles require access to the libraries that implement encryption, signature, and other security algorithms that transform the XML messages before sending and after receiving them. You must prepare an environment with these libraries to use SOAP security, set the class path of the Java™ Runtime Environment (JRE) that Eclipse uses, and set the class path of the virtual machine that the Agent Controller uses.

    - Recording service tests
      When you record a test, the test creation wizard records your interactions with the service, generates a test from the recording, and opens the test for editing. You can record a test session by invoking service calls with the generic service client or by using an existing client. You can also create a service test manually or from a Business Process Execution Language (BPEL) model.
      - Service testing guidelines
        Before you can test a service, you must set up your test environment and incorporate these guidelines in order to produce reliable tests.
      - Verifying WSDL syntax compliance for JMS services
        Various Java™ Message Service (JMS) providers vary in the syntax used for describing services. Before testing JMS services, you must ensure that Web Services Description Language (WSDL) files comply with the requirements of the tool.
      - Configuring the environment for SOAP security
        SOAP security profiles require access to the libraries that implement encryption, signature, and other security algorithms that transform the XML messages before sending and after receiving them. You must prepare an environment with these libraries to use SOAP security, set the class path of the Java™ Runtime Environment (JRE) that Eclipse uses, and set the class path of the virtual machine that the Agent Controller uses.
      - Recording a service test with the generic service client
        You can record a service test by invoking service requests with the generic service client. After you have sent the requests and received the responses from the service, select the results in the History section of the generic service client to generate a test. If you do not have access to a dedicated client for the service calls, the generic service client is the easiest way to generate the calls and to record a test.
      - Recording a service test through a client program
        You can record tests for SOAP-based, XML, plain text, or binary services with any client program that uses the HTTP protocol. To record the test, the recorder intercepts the service calls and message returns between the client and the service. You can choose between an HTTP or SOCKS proxy recorder or a low-level socket recorder, depending on the capabilities of the client program.
      - Preparing to record a test for the HTTP/2 service
        To test a web service that is based on the HTTP/2 protocol, record a test by using the SOA extension of Rational® Performance Tester. Before recording the HTTP/2 service, follow the procedure in this topic to configure your computer.
      - Creating a service test from a BPEL model
        You can use Business Process Execution Language (BPEL) resources from your workspace to automatically generate a set of service tests that corresponds to the paths that are run in a synchronous BPEL model.
      - Creating a service test manually
        You can create a service test without recording by simply adding the test elements as required and manually editing the test element details in the test editor.
      - Creating a service test for WebSphere® MQ
        You can create an IBM® WebSphere® MQ test by adding the test elements as required and editing the test element details in the test editor.
      - Creating a service test for WebSphere Java MQ
        To test Java-based applications, create a service test and add the WebSphere Java MQ messages. You can create a service test by using Generic Service Client option or the New Service Test wizard .
      - Creating an XML call test manually
        You can create a test for a plain XML call over HTTP, JMS, or IBM® WebSphere® MQ, by simply adding the test elements as required and editing the test element details in the test editor.
      - Changing service test generation preferences
        You can change default test generation values by changing the preference settings. The default settings, however, are appropriate for recording in most cases.
    - Recording socket and TN3270 tests
      When you record a test, the test creation wizard records your interactions with the application under test, generates a test from the recording, and opens the test for editing.
    - Digital certificates overview
      The digital certificates feature enables you to run tests against servers that use Secure Sockets Layer (SSL) for applications that require client-side digital certificates to authenticate users.
    - Kerberos overview
      You can run HTTP tests against servers that use the Kerberos protocol for authentication.
    - Annotating a test during recording
      You can add comments, add transactions, or change a page name while you record a test. The advantage of adding these elements during (rather than after) recording is that you can place the annotations in the test exactly where you want. In addition, because annotations are part of the recorded test, they are regenerated when you regenerate the test. You can also insert split points into a test during record.
    - Recording sensitive session data
      You can keep recording session (.recsession) files to view the contents of a recording or to regenerate tests. However, if a recorded test contains sensitive information, you can choose to obfuscate, or encrypt, text strings in the recsession file.
    - Splitting a test during recording
      You can insert split points when you record a test. Split points allow you to generate multiple tests from a single recording that you can replay in a different order with a schedule.
    - Generating a new test from a recorded session
      You can generate a new test from a recorded session. For example, if you accidentally damage a test during editing, or if you want to change a test preference, you can regenerate the test instead of re-recording it. If split points were inserted in the recording, you can choose to generate a single test without split points.
    - Organizing test assets by type
      By clicking an icon, you can view your test assets in a logical order, in separate folders for tests, schedules, results, locations, and datasets.
  - Editing tests
    After you record a test, you can edit it to include datasets (to provide variable data rather than the data that you recorded), verification points (to confirm that the test runs as expected), and data correlation (to ensure that returned data is appropriate for the corresponding request). You can also add protocol-specific elements to a test. When you edit a test, the modified items appear in italic type. The italic type changes to regular type after you save the test.
  - Compound tests
    You can create compound tests to help you organize smaller tests into scenarios that can then be run end-to-end. You can combine tests from different extensions to achieve end-to-end flow.
  - Simulating services with stubs
    Service stubs enable you to simulate the behavior of an actual service for a wide variety testing or integration purposes.
  - Sending service requests with the generic service client
    The generic service client enables you to send requests to services for which you do not have a convenient client and to view the responses returned by the service.
  - Emulating workloads
    You emulate a workload by creating a schedule and adding user groups/rate runner groups, tests, and other elements to it.

Configuring the environment for SOAP security

SOAP security profiles require access to the libraries that implement encryption, signature, and other security algorithms that transform the XML messages before sending and after receiving them. You must prepare an environment with these libraries to use SOAP security, set the class path of the Java™ Runtime Environment (JRE) that Eclipse uses, and set the class path of the virtual machine that the Agent Controller uses.

Before you begin

Before you can test SOAP-based services that use security algorithms, you must obtain a set of security libraries and configuration files for SOAP.

BouncyCastle (http://www.bouncycastle.org) is a provider of such security libraries. Use of these security libraries is optional for the Rational® test product.

Procedure

Copy the library files into the jre/lib/ext of the JRE installation.
By default, this is the following directory: C:\Program Files\IBM\SDP\jdk\jre\lib\ext
Add the following VM argument either to the Eclipse launch command line or to the eclipse.ini file: -vmargs-Dosgi.parentClassloader=ext

The eclipse.ini file is located in the same directory as the eclipse.exe launcher binary that is used to run the product.

What to do next

To configure a remote computer that uses only the Agent Controller and does not require access to the workbench, perform only step 1 and restart the Agent Controller service.

After configuring the environment, you must import a Web Services Description Language (WSDL) file and use the WSDL security editor to set up a security profile for the WSDL file.
