Learn about new features, behavior changes, and other updates in TestStand 2021.

Sweep Loop Step Enhancements

TestStand 2021 expands the functionality of the existing Sweep Loop step. These updates include the following changes:

  • You can create nested and parallel sweeps of parameters by changing the level of one or more parameters in a Sweep Loop step.
  • TestStand automatically creates a variable when you specify a parameter name.
  • You can choose between Static and Dynamic mode to specify whether values for a Strategy are specified using constants or expressions.
  • You can use the Table View to interact with values and test vectors resulting from a sweep across selected parameters at edit time and run time. This functionality includes the ability to enable or disable, filter, and export test vectors.
  • At execution time, use Table View to monitor captured data as well as the parameters in the Sweep Loop step.
  • Added functionality to import and export parameter and test vector data to or from a CSV file.
