TestStand groups the core set of built-in step types into the following categories:

  • Step types you can use with any module adapter. Step types such as the Numeric Limit Test and the String Value Test call any code module you specify. They also might perform additional actions, such as comparing a value the code module returns with limits you specify.
  • Step types that always use a specific module adapter to call code modules. Sequence Call is the only step type in this category.
  • Step types that perform a specific action and do not require you to specify a code module. Step types such as Message Popup, Statement, and Flow Control perform actions you configure on an edit tab or in an edit dialog box specific to the step type.
Note TestStand also includes application-specific step types. For example, TestStand provides sets of step types to more easily synchronize multiple threads, access databases, control modular instruments, control IVI instruments, and access VIs and remote systems.
