Eight main principles underlie agile testing. They are as follows:

• 
  Practice of continuous testing: Agile teams continuously test their products to ensure that they are improving. It is carried out alongside development.


• 
  Feedback on an ongoing basis: Agile testing provides team members with ongoing feedback and ensures that the product meets its business objectives. Feedback is primarily focused on quality rather than requirements.


• 
  Participation of the entire team: In agile methodologies, developers, business analysts, and testers all take part in the testing process.


• 
  Speeding up feedback: Agile involves the business team during each iteration, resulting in faster feedback and a lower cost associated with repairing errors.


• 
  Quality comes from clean code: Testing the software regularly allows issues and vulnerabilities to be detected and fixed during the same iteration, maintaining code integrity.


• 
  Fewer Documentations: Agile testers use reusable checklists rather than long, bloated documents and concentrate on the essence of the test rather than on the incidental details.


• 
  Test-Driven: Unlike conventional methodologies, agile testing involves testing during the actual implementation process.


• 
  Client satisfaction: The client can see their product being developed and make changes and updates to it as it evolves. The test procedures can be updated to fit the current requirements.
