Preconditions Panel

The Preconditions panel specifies the conditions that must evaluate to True for TestStand to execute a step during the normal flow of execution in a sequence, such as running a step only if a previous step passes. The Preconditions panel contains the following options:

  • Precondition Expression—The expression that must evaluate to True to execute the step.
  • Precondition Builder—Launches the Preconditions Builder dialog box, in which you can build a precondition expression using step statuses, AllOf and AnyOf conditional groups, and subexpressions.
  • Expression Browser Dialog Box—Launches the Expression Browser dialog box.
  • Check Expression for Errors—Verifies the syntax of the expression in the Expression control.
