What does the syntax {B[BufferName]} specify?

• A. A command to create a new buffer with the given name.
• B. The Buffer named BufferName to store or retrieve data.
• C. A pointer to a built-in global variable.
• D. An instruction to clear the buffer.

Answer: (B)

The syntax {B[BufferName]} is a dynamic reference to a named data buffer. Here, B indicates a Buffer, and BufferName is the identifier you’ve given to that buffer. The curly-brace notation tells Tosca to resolve this at runtime, pulling the value stored in that specific buffer or, when used in a store operation, directing data into that buffer. It’s not creating a new buffer or pointing to a global variable; it’s simply accessing the data stored in the named buffer so you can reuse it later in the test. For example, after capturing a value into a buffer called CustomerID, you can use {B[CustomerID]} in a subsequent step to reuse that value.
