Testing

• Component Testing

  • Pieces of software code such as subroutines, procedures or functions that can be complied and executed on their own.
  • They should be testing individually before being integrated into the main program to ensure they work.
  • The program is tested by the programmer who knows the code and how it works.
• Integrative Testing

  • Modules are a collection of dependent components, procedures and functions designed to be part of the main program.
  • They are not complete programs and can’t run independently.
  • Small programs are created that will allow modules to run so that it can be properly tested.
  • Integrative testing is when you put components together that work together and test that this sub-program is working.
  • If your program is working with another piece of software e.g. a database, integrative testing is also when you make sure that they work together.
• Usability testing based on prototypes

  • If a program has clear and concise information and it is easy to navigate for a range of users, it is described as having good usability.
  • Prototypes have been agreed with the end-user earlier on.
  • To ensure that the software is usable it should be compared with the prototype ensuring that it works the same way.
• Final Testing

  ·       This is the final stage in the testing process before the system is accepted for operation use.

  ·       The system is tested with data supplied to the client rather than simulated test data.

  ·       It may reveal errors and omissions in the system requirements because of the real data.

  ·       It may also reveal problems where the software does not meet the user’s needs.
• End-User Testing (Beta Testing)

  ·       The system is installed on the client’s site and is subjected to acceptance testing by the client.

  ·       This is a test for a software product prior to release.

  ·       The clients use the program for a given period and then report back to the development team.

  ·       The process might  be iterative, with the development team making adjustments to the software.

  ·       When the clients regard the program’s operation as acceptable, the testing stage is complete.
• Component Testing


  Component testing is a process used to verify the functionality and reliability of individual components (like sub-routines, functions, or modules) in a software application.
• Integrative Testing


  Integration testing is all about ensuring that different components of a software system work together as expected. 
• Usability testing based on prototypes


  Usability testing with prototypes is like taking a test drive. 
• Final Testing

  This is the final stage in the testing process before the system is accepted for operation use.
• End-User Testing (Beta Testing)


  End-User Testing, or Beta Testing, involves releasing a near-final version of software to actual users for real-world testing and feedback before the official launch.
