Software Testing Explanation and their Advantages and Disadvantages

Software testing is to confirm that the computer program behaves in a very such way as per Business needs. Testing is finished to confirm that the final product is bug free and to validate that  what has been given is what the client is needed.


Blackbox Testing

Blackbox testing is a checking out approach that ignores the inner mechanism of the system and focuses on the output generated against any enter and execution of the machine. it is also referred to as purposeful testing.

  • The testers have no information of how the device or element is established within the field. In blackbox testing the tester is concentrating on what the software program does, not how it does it.
  • His definition mentions each purposeful and non-practical testing. Useful testing is involved with what the machine does its functions or capabilities. Non-purposeful trying out is worried with inspecting how well the gadget does. Non-functional trying out like overall performance, usability, portability, maintainability, etc.


  • Creating test cases are easy.
  • Tester no need to be a technical guy.
  • Testing helps to identify unclearness and differences in functional specifications.


  • Documenting the test cases are difficult.
  • Difficult to identify all possible inputs in a limited testing time.
  • High chances in forgetting an input test case.

Whitebox Testing

Whitebox is a testing method that takes into consideration the inner mechanism of a gadget. It is also called structural checking out and glass container whitebox testing.

Blackbox testing is frequently used for validation and whitebox testing is often used for verification.


  • Does not need a complete GUI to test this testing.
  • Can discover errors early in the development process.
  • Helps to reduce the code.


  • Software development time is high.
  • Tester should be a technical guy.
  • Separating code and test cases are hard.
