   What is the primary purpose of basis path testing as a white-box test technique?

   • ATo design a minimal set of test cases that execute every independent path through the code
   • BTo test the system's behavior from the user's perspective without internal knowledge
   • CTo ensure that every line of code is executed at least once
   • DTo verify that all possible combinations of input values are tested

   What is the primary goal when deriving test cases from basis paths?

   • ATo achieve 100% statement coverage only
   • BTo test all possible input combinations
   • CTo verify the program's output for a single representative input
   • DTo execute each independent path at least once

   A test analyst is constructing a control flow graph from the following pseudocode: IF condition A THEN statement X ELSE statement Y ENDIF statement Z. Which of the following correctly describes the control flow graph structure?

   • AA sequence of 4 nodes with no decision points
   • BA loop structure where statement Z is repeated until condition A is false
   • CA decision node with two outgoing edges that merge back into a single node before statement Z
   • DTwo separate paths that never merge, creating two exit points

   A test analyst is explaining basis path testing to a junior tester. The junior tester asks why basis path testing is considered a white-box technique. What is the most accurate explanation?

   • AIt focuses only on the external behavior of the system
   • BIt tests the system through the user interface without examining internal code
   • CIt uses the internal structure of the code to derive test cases
   • DIt tests the system's performance under load
