Decision table method for basic content learning of software testing (2)

• Design test points for multi conditional dependencies

* Decision table method

   explain ： Definition ： A tool for expressing multi conditional logical judgment in the form of tables

       Part of the ： Conditions , action

      The rules ： A rule is a column that runs through conditions and actions in the judgment table .

（ Yes N Conditions , There are two values for each condition ,0 and 1. The whole combination has 2 Of n Power ）

Steps for use case design by judgment table method ： Clear requirements 、 Draw a decision table 、 Write test cases according to rules .

Case study 1：

 

Case study 2：

 

Use scenarios ： There are multiple input conditions , Multiple output results , There is a combination relationship between input conditions , There is a dependency between input conditions and output conditions

     The decision table is generally applicable to the case where the number of condition combinations is small . There are dependencies between multiple conditions , fit 4 Within conditions , exceed 4 Can use orthogonal method .
