Example: Performing a Null Check on a Variable

In this example, we explain how to check whether a given variable is null.

• Action: Null Check

• Input Value: {Username}

  • The argument ({Username}) specifies the variable to be checked for null or empty value.

• Output Value: {Status}

  • The result of the null check is stored in the {Status} dynamic variable, with the following possible values:

    • True: If the variable is null or empty.

    • False: If the variable contains a value.

• Logical Explanation: The Null Check action reads the value from the Input Value column ({Username}). It evaluates whether the variable is null or empty. The result of this evaluation (True) is stored in the {Status} variable.

Note: In this example, a test step with the Create Dynamic Variable action is used to verify that the dynamic variable contains a value.
