How to Design Test Cases --- April 21, 2018

 
  As testers, how should we design test cases: 
 

 
  The idea of ​​test case design mainly depends on thinking, 
 

  
   Principles: 1. When designing test cases, it is necessary to simulate some normal, abnormal, extreme and other situations that may occur;

  
   2. When testers cannot design test cases, they can regard themselves as users and how to use the product;

  
   3. Check whether the product meets the needs of customers and whether the functions on the page can work normally.

  
   Method: 1. Demand transformation method (
   
  Any sentence, every word
   ) --- whether it meets the requirements document

  
   2. Equivalence class, boundary value (method of designing test cases)

  
   3. Error inference method (summarize the problems that have occurred in the past, design test cases)

  
   4. Cause and effect diagram (determination table)

  
   5. Orthogonal experiment method (typical test factors and states, combinations)

  
   6. Long-term experimental method (based on personal experience of using the product)

  
   7. Exploratory testing (whether everything works properly)

  
   8. Guessing method (this method is mainly based on the accumulation of your own work experience)

 
Requirements understanding is important (be like product people)
