In a control flow graph, what does a node typically represent?

A decision point such as an if or loop condition

A basic block of sequential statements with a single entry and exit

A function call or method invocation

In which phase of the software development lifecycle is basis path testing most appropriately applied?

During acceptance testing to confirm user requirements are met

During requirements analysis to validate user stories

During system testing to verify end-to-end business flows

During component testing after the code has been written

A test analyst is constructing a control flow graph for a function that contains a WHILE loop. The loop condition is evaluated at the top of the loop. How should the loop be represented in the control flow graph?

As a sequence of nodes with no decision point

As two separate decision nodes connected by an edge

As a decision node with one outgoing edge back to itself and one outgoing edge to the next statement

As a single node that represents the entire loop
