Describe the purpose of a WHILE statement in Tosca.

• A. An action that updates data without looping.
• B. An IF statement that checks a condition once.
• C. A loop that runs until the condition becomes true.
• D. A loop that repeats steps as long as a condition is met.

Answer: (D)

WHILE in Tosca is a loop that repeats a set of steps as long as a given condition is true. It checks the condition before each iteration, and if it evaluates to true, the body of the loop runs and then the condition is checked again. This continues until the condition becomes false, allowing you to automate repetitive actions until a desired state is reached, such as waiting for a UI element to appear or for data to meet a certain criterion.

The other descriptions don’t fit because they describe actions without looping, or a one-time check, or a loop that continues until the condition becomes true—which would mean it stops when the condition becomes true, the opposite of how a WHILE loop operates.
