Teory of program testing - Coggle Diagram

- - - - from
        
        namely
        
        requirement specification
        
        source code
- - - - faults occur due to our inadequate
        understanding of all conditions with which a program must deal
      - Faults occur due to our failure to realiza that certain combinations of conditions requiere special treatments
    - - logic fault
        
        design fault
        
        construction fault
      - performance fault
        
        missing control flow paths
        
        inappropiate path selection
        
        Inappropiate or missing action
        
        following to test
        
        identify all the conditions relevant to the correct operation of a program
        
        select test data to exercise all possible combinations of these conditions
    - - Test data
        
        values from input domain of a program that collectively satisfy some test selection criteria
      - test predicate
        
        description of conditions and combinations of conditions relevant to correct operation of the program
- - - - test cases are derived solely based on the source of a system
    - - test cases are derived solely based on th specification of a system
    - - test cases based on their expectations from the product at the time of talking delivery of the system
    - - fault seeding
        
        implanting a certain number of faults in a program P and executing P with test set T
      - program Mutation
        
        a mutation is a program obtained bt making a small change to P
    - - two main limitations of testing
        
        One we have selected a subset of the input domain
        
        testing means executing a program with a generally small.
