Web-based Correlation Using Design Studio

This topic describes how to use the Correlation tab of the Design Studio to correlate Vuser scripts.

Prerequisites

  1. Record a script using one of the following protocols:

    • Web HTTP/HTML
    • Flex
    • RTMP/RTMPT
    • Citrix
    • SAP - Web
    • Oracle NCA

      Note: You can only correlate the Web HTTP/HTML steps within your Oracle NCA script and the Web HTTP/HTML protocol must be active. To activate, select Recording Options > Protocol > Active Protocols > Web HTTP/HTML.

      For additional information on manual correlation, see Oracle NCA Correlation

  2. Verify that Record > Recording Options > Correlations > Configuration has all scan types enabled.

Using the Correlation tab

  1. Click the Design Studio button to perform an initial scan. This will open the Design Studio dialog box which will scan for response (or record based) correlations and apply correlation rules. The progress bar in the dialog box indicates if the initial scan was successful.

    For details on the Correlation tab, see Correlating Values.

    Note: If no dynamic values for correlation are found, a warning is displayed, advising you to check your recording options. Verify that Record > Recording Options > Correlations > Configuration has all scan types enabled.

  2. Select which values to correlate by highlighting the value in the grid and clicking the Correlate button.

    When a value is correlated, VuGen adds a web_reg_save_param_* function, and saves the original value in a comment in the script.

    You can examine the details of the correlation by expanding the Details Chevron in the dialog box. For details, see Correlating Values.

    For details on the Correlation tab, see Correlating Values.

  3. Click the Add as Rule button to add a rule type . In addition, you can click the Edit rule button to view and edit the corresponding rule if the dynamic value was correlated by a rule. For details, see Correlations > Rules Recording Options.
  4. Click the Replay and Scan button. The Correlation tab progress bar indicates if additional correlations have been found. Again, you can select which values you would like to correlate by highlighting the value in the grid and clicking the Correlate button. You may need to repeat this step several times.
  5. When Design Studio no longer finds new correlations, the progress bar will display Design Studio Scan Complete.

    Tip: If Design Studio does not resolve all correlation-based errors, try to resolve them using manual correlation. For details, see Manually Correlate Scripts.
