Target Program

Add two identical input boxes to the previous one

Introduction to How to use

    • Causality Diagram method

In introduction to software testing by Paul, the coverage criteria for software testing are divided into four categories, logical expressions,syntactic Descriptions,graphs,input Domain characterizations, as far as I can see, equivalence class partitioning belongs to input domain characterizations, control flow and data flow test belong to graphs, and causality diagram method belongs to logical Expressions It finds the cause (input condition) and the fruit (output or program state change) from the description of the program specification written in natural language, and can be converted to a decision table by causality diagram.

    • Steps
      list cause and effect
      draw a causal diagram
      judging form According to the cause and effect drawing
      If there are too many variables, you can simplify the decision table before you design the test case
