Testing Regular Expressions

As you develop applications in the Application Composer, you can test regular expressions to determine whether they match alphanumeric strings.


  1. In the Application Composer, select a state.
  2. Click the ? icon to the right of the Assign To field for a follow-up state.
    The expression tester opens and populates Expression and Assign To fields with follow-up state values from the state editor.
  3. Enter the value to test in the Text to Test field, and click Test.


The result is either:
  • Match – value in Expression field matches the value in Text to Test field.
  • No Match – expression value does not match Text to Test value.
