What is Graph Matrix? A graph matrix is a square matrix whose size represents the number of nodes in the control flow graph.  Each row and column in the matrix identifies a node and the entries in the matrix represent the edges or links between these nodes. Conventionally, nodes are denoted by digits, and edges are denoted by letters. Example: Graph Examples Since the graph has 4 nodes , so the graph matrix would have a dimension of 4 X 4 . Matrix entries will be filled as follows : (1, 1) will be filled with ‘a’ as an edge exists from node 1 to node 1 (1, 2) will be filled with ‘b’ as an edge exists from node 1 to node 2. It is important to note that (2, 1) will not be filled as the edge is unidirectional and not bidirectional (1, 3) will be filled with ‘c’ as edge c exists from node 1 to node 3 (2, 4) will be filled with ‘d’ as edge exists from node 2 to node 4 (3, 4) will be filled with ‘e’ as an edge exists from node 3 to node 4 Connection Matrix A connection matrix is a ma...

Software Testing process Software testing process 1. Test Strategy and Test Plan Every project needs a Test Strategy and a Test Plan. These artifacts describe the scope for testing for a project: The systems that need to be tested, and any specific configurations Features and functions that are the focus of the project Non-functional requirements Test approach—traditional, exploratory, automation, etc.—or a mix Key processes to follow – for defects resolution, defects triage Tools—for logging defects, for test case scripting, for traceability Documentation to refer, and to produce as output Test environment requirements and setup Risks, dependencies, and contingencies Test Schedule Approval workflows Entry/Exit criteria And so on… Whatever methodology your project follows, you need to have a Test Strategy and Software Testing Plan in place. Make them two separate documents, or merge them into one. Without a clear test strategy and a detailed test plan, even Agile projects will find i...
