3/12/2014

You can use the Compact Stress tool, which is installed by default with the Windows Embedded Compact Test Kit (CTK), to stress-test your device. The Compact Stress tool is designed to help identify bugs that may exist in your system image. The Compact Stress tool includes a Compact Stress Configuration Editor that you use to create test-case input for the Compact Stress tool.

The features of the Compact Stress tool are:

  • Runs created stress-mix configurations
  • Creates and edit stress-mix configurations
  • Includes a stress-mix configuration editing tool
  • Provides modular-level results
  • Provides device-side log entries
  • Diagnoses device and output .xml files

The general steps to complete a stress-test run are:

  1. In the Compact Stress Configuration Editor, select the test modules to add to your stress-test mix and create your configuration file. A stress-test mix is a collection of test modules that are run during the stress-test.
  2. Run the Compact Stress tool using your stress-test mix as input.
  3. View the results.

Use the Configuration Editor to Define Test Parameters

The Compact Stress tool uses a stress-mix file (also called a configuration file) as input when it executes a test pass. You use the Compact Stress Configuration Editor, which is installed by default with the Windows Embedded Compact Test Kit (CTK), to create or edit this stress-mix file by entering information about the stress testing you want to perform. The Configuration Editor gives you access to module templates and module types with which you can customize your test pass.

Create the Configuration File

The stress-mix configuration file contains the modules that the Compact Stress tool uses to perform a stress test on your device.

To create the stress-mix configuration file

  1. In the Windows Embedded Compact Test Kit (CTK), on the Start Page and under Getting Started, click Connect to Device.

    Note

    Before you connect to a device from the Windows Embedded Compact Test Kit (CTK), the device must be running and must be attached to Platform Builder. For more information, see Connect to a Device.

  2. In the Select a Device dialog box, choose your device, and click OK.

  3. On the Tools menu, click Compact Stress Configuration Editor.

  4. In the Compact Stress Configuration Editor window, from the File menu, click New Mix.

  5. Navigate to the Configuration folder, and then to the Modules folder.

  6. From Modules, add modules to a one of the listed module templates by right-clicking a module template, and then selecting Add Existing Module.

  7. In the Choose Module Type dialog box, select the test module type that you want to add to your selected module template, and then click OK.

    The following table describes the module types in the Choose Module Type dialog box that are available to add to your chosen template.

    Note

    There is no pause functionality. If you stop the run, clicking the Start button restarts the test from the beginning.

View the Compact Stress Tool Results

Throughout the testing process, you can view the Compact Stress tool test results in real time by using the Output File button, which is enabled when the stress test begins and remains enabled throughout the test. We recommend that you wait to open the test results file until the test run finishes. When the stress test finishes, a status message appears in the Compact Stress Messages window.

To view the Compact Stress results

  1. In the Remote Tools Shell window, click the Output File button while a test is running.

    A window, based on your default XML viewer, appears and presents a preview of the test output .xml file, which is labeled CompactStressresults_<DeviceName>_<Test Run Date and Time>.xml. This preview of the test results is a preview of the .xml output file that, when the test is finished, will contain the complete details of the test.

    Note

    The output file is constantly updated until the test pass ends. Thus, to be sure you are viewing the complete output, you should only open the actual output file after the test run has completed.

  2. When the test run has completed, you can view the results by opening the output file CompactStressresults_<DeviceName>_<Test Run Date and Time>.xml by using the XML viewer of your choice. Typically, the completed output file is located at:

    C:\Users\<UserName>\Documents\CompactStress.
