When using {XB[Value]}, what does the content inside the brackets represent?

• A. The actual content to compare.
• B. The index of the test step.
• C. The type of data being read.
• D. The name of the Buffer.

Answer: (D)

In this syntax, the brackets hold the identifier of a Buffer. The value inside {XB[...] } isn’t the actual data itself; it’s the name of the Buffer that was populated earlier. At runtime Tosca looks up that named buffer and uses whatever value was stored there. So the content inside the brackets is the Buffer’s name, which is why this reference can dynamically supply data to the current step. For example, if you saved a user name into a buffer named UserName, {XB[UserName]} will provide that stored value when the step runs. This isn’t the literal data, nor an index or a data type—just the name used to retrieve the stored value from the buffer.
