What criteria indicate the completion of the testing process of a program or system?

The completion of the testing process for a program or system is usually determined by the following criteria:

• All planned test cases executed: all tests specified in the test plan have been successfully passed.
• No critical defects: found bugs are fixed or their impact is not critical for release.
• Achievement of quality targets: for example, code coverage by tests, performance, security.
• System stability: the application operates without failures for a certain period.
• Compliance with requirements: functional and non-functional requirements are met.
• Stakeholder approval: the customer or project manager confirms readiness.

These criteria help determine whether the product is ready for release or for moving to the next development stage.
