What is the meaning of a Library in Tosca with respect to reusable steps inside?

• A. TestCase Steps
• B. Reusable TestStepBlocks
• C. Library Units
• D. TestStepBlocks

Answer: (B)

In Tosca, a Library is a place to store blocks of steps that you want to reuse across tests. These reusable blocks are called TestStepBlocks. A TestStepBlock groups several steps into a unit that can be inserted into multiple TestCases, often with parameterization to adapt to different contexts. That’s why the library’s meaning with respect to reusable steps is the concept of reusable TestStepBlocks: you define the block once and reuse it wherever needed, maintaining consistency and reducing duplication. TestCase Steps reside inside individual tests and aren’t meant to be shared through the library, while “Library Units” isn’t the standard term used for this purpose.
