Prerequisite: Software Testing

Independent Testing is a collection of tests done by a specific corporation, person, or agency that software system according to desired requirements. 


The term is defined as independent because it’s neither connected with the producer nor the user.

This also consists of some third-party testing referred to as contrast testing or evaluation facilities.  


  1. It determines that work is done according to the needs of the specification, regulation, or not.
  2. It figures out if the upcoming products/programs are on track.
  3. Supplies standard data for scientific engineering and quality assurance functions.

  5. Provides a medium for technical communication.
  6. Gives evidence in legal proceedings, product claims, etc.


Independent Testing services possess some beneficial features throughout the process, some of them are as follows:

  4. Testing is done by some independent testing team from another group of the same organization.
  5. Testing is done by some independent testers from other organizations.

Benefits of Independent Testing

  2. Unique side assumptions and ideas of independent testers result in identifying hidden defects.
  3. The independent testers are unbiased.
  4. Cost-effective as it has a separate budget, which helps in tracking money spent on training, testing tools, equipment.
  5. Provides improved Software Quality.
  6. Supplies more Experienced and skilled power.

  2. Easily gets affected by delays in the early stage because it’s the execution of the last stage.
  3. Developers don’t take the responsibility of quality and let the testing team deal with the whole issue.
  4. Sometimes independent testing adds hindrance to communication.
  5. Faces lack identification in project goals and a few more uncertain things.
