What does the syntax {PL[ParameterName]} denote?

• A. A Buffer value
• B. A TCP value
• C. A Test Configuration Parameter
• D. A Business Parameter reference

Answer: (C)

That syntax pulls a value from the Test Configuration Parameters. The {PL[ParameterName]} placeholder is used to fetch the value of a parameter defined in the test configuration, so the test step can use environment-specific data without hard-coding it. At runtime Tosca replaces {PL[ParameterName]} with the actual value you set for ParameterName, making tests data-driven and easier to maintain. This is different from values sourced from buffers, TCP data, or business parameters, which come from other mechanisms; using a Test Configuration Parameter keeps configuration centralized and swap-able when you run tests in different environments.
