Purpose

This example simulates the testing of a computer motherboard using test steps that use the HTBasic Adapter. The example calls subsequences in the CPU Diagnostic Sequence.seq and CPU Test Sequence.seq sequence files.

None

Prerequisites

The example contains sequence files designed to work with HTBasic 8.0.

When you use the demo version of HTBasic, you must configure the HTBasic Adapter to use the HTBasic demo server. Select the Use HTBasic Runtime Server option in the HTBasic Adapter Configuration dialog box and specify the path and filename for HTBwin.exe.

Note (64-bit TestStand) 64-bit TestStand does not support the HTBasic Adapter.

How to Use This Example

Complete the following steps to use this example.

  1. On the Steps pane of the MainSequence, review the steps in the Main step group.
    • The Powerup Test step, which is a Pass/Fail Test step, simulates a power-up test. Each of the five test steps that follow the Powerup Test specifies a precondition expression that executes the step only when the Powerup Test step passes.
    • The CPU Test step, which is a Sequence Call step, calls the MainSequence in the CPU Test Sequence.seq sequence file to simulate CPU tests.
    • The ROM Test, RAM Test, Video Test, and Keyboard Test steps simulate tests. Each of the diagnostic steps
    • The Powerup Diagnostics step, which is a Numeric Limit Test step, simulates a power-up diagnostics test. Each of the five diagnostic steps that follow the Powerup Diagnostics step specifies a precondition expression that executes the step only when the corresponding test step fails.
    • The CPU Diagnostics step, which is a Sequence Call step, calls the MainSequence in the CPU Diagnostic Sequence.seq sequence file to simulate CPU diagnostics.
  2. Select Execute»Single Pass to run the sequence.
  3. When execution completes, review the report on the Report pane to see how TestStand reports the passed and failed steps.
