For Step
Use a For step to define a block of steps that execute repeatedly for a number of iterations.
Configuring the Step
Use the For Loop edit tab in the TestStand Sequence Editor and the Configure For Loop dialog box in a TestStand User Interface to configure the For step.
Step Properties
In addition to the common custom properties , the For step type defines the following step properties:
- Step.InitializationExpr —The expression the step evaluates before executing the steps within the block the first time. The expression typically initializes a count variable.
- Step.ConditionExpr —The expression that must evaluate to True for the steps within the For block to execute.
- Step.IncrementExpr —The expression the step evaluates after each execution of the steps within the block. The expression typically increments a count variable.
- Step.CustomLoop —The step uses custom expressions to define the looping behavior for the steps within the For block.
