    - Editing Socket tests
      Improve the Socket tests by adding test elements.
      - Socket API test editor overview
        You use the test editor to inspect or customize a socket API test that you recorded.
      - Adding elements to a socket test
        A socket test provides the flexibility to add close, send, and receive elements to the test.
        Adding a socket close
        You can manually add a socket close element to a socket API performance test.
        Adding a socket send
        You can manually add a socket send element to a socket API performance test.
        Adding a socket receive element
        You can manually add a socket receive element to a socket API performance test.
      - Verifying application behavior
        Add the different verification points to verify the responses in a socket test.
      - Merging socket send and receive elements
        With the Organize wizard, you can merge consecutive send or receive elements that use the same connection to improve the clarity of your socket test.
      - Changing multiple socket send and receive elements
        You can perform global changes to multiple send and receive elements in a socket test.
      - Splitting a socket test
        After you record a test, you can split it into smaller tests. Splitting tests enables you to create modular building blocks of smaller tests and combine them to make bigger tests. The original test is unchanged. You can recombine these building blocks in a schedule, including loops and conditions.
      - Using custom code to specify an end policy
        You can write a custom Java™ class to specify when a socket receive element stops receiving. This offers the most flexibility, but requires that you write your own Java class using the Rational® Performance Tester extension API.
      - Using custom code to manipulate data
        You can write a custom Java™ class to manipulate data in a send element. This offers flexibility for injecting data in test, but requires that you write your own Java class using the Rational® Performance Tester extension API.
    - Editing Kerberos tests
      You can change the Kerberos realm, user name, and password when editing tests.
    - Adding test elements
      You can add a variety of elements to a test, such as transaction blocks, IF-THEN conditions, loops, and comments.
    - Searching within tests
      Search request data or response content by right-clicking in the data or content and selecting Find. To search for specific element types and to display the results in a table, click Select. For a still more powerful search and replace, use the Test Search function.
    - Exporting a test
      To share the test scripts with manual testers or reviewers who do not have the workbench, export the test scripts to text files. You can export one file at a time.
    - Copying test assets with dependencies
      You can export test assets, and then import them into another project or workspace without losing any dependencies. Test assets include projects, schedules, and tests. You can export and import test assets to collaborate with other testers.
    - Disabling portions of a test
      When you disable portions of a test, you can still see the disabled portion, but it is not executed during a run. You can also disable portions of a schedule by using the following procedure.
    - Running test elements in random order
      You can record multiple user scenarios in a test and then run each scenario in a random order. To do this, you put each scenario under a random selector and then select the proportion of time that the scenario should be run.
    - Renaming test assets
      As your test assets increase and become more complex, you might want to rename them. Use the Eclipse Rename function or save the assets under a different name.
    - Deleting test assets
      As your test assets grow and become more complicated, you might want to delete the assets that you no longer use.
    - Debugging custom code for tests and compound tests
      If you have custom code added to a test or a compound test, you can debug the custom code for any errors by clicking the Debug button.
    - Providing tests with variable data (datasets)
      You can produce more realistic tests by changing them to use datasets. During execution, a test that uses a dataset replaces a value in the recorded test with variable test data that is stored in the dataset. This substitution allows each virtual user to generate a different request to the server.
    - Test variables
      A test variable is a user-defined, name-value pair that stores and refers to information throughout a test and between tests.
    - Correlating response and request data
      For a test to run correctly, a request that is sent to a server might need to use a value that was returned by a previous request. By ensuring that this data is correlated accurately, you can produce better performance tests.
    - Data transformation
      You can transform HTTP application specific data such as JSON data, binary data and encoded data to a more readable format to use data correlation.
  - 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.

Adding a socket close

You can manually add a socket close element to a socket API performance test.

Before you begin

In a performance test, socket close elements close the connection to a server. A socket close element relates to a specific socket connection.

Ensure that for each socket connection, there is a corresponding socket close. If not, during the test run, the operating system can run out of socket handles, causing the test to fail.

Procedure

Open the performance test in the test editor.
In the Test Contents area of the test editor, right-click the test node, and click Add > Socket Close.
In the Test Element Details section, click Change and select the socket connection that you want to close.
You can specify a Think Time delay before the test establishes the connection.

Results

After you have closed a connection, you can no longer send or receive data from that connection. If any test elements use a connection after the close element, they are flagged with an error in the test editor.
