When can testing be considered complete?

Testing can be considered complete when there is enough information for release decisions because this reflects the primary goal of testing: to provide stakeholders with the necessary insights to make informed decisions about software release. This involves assessing the quality and readiness of the product, balancing factors such as defect status, product risk, and business requirements.

When sufficient information has been gathered, stakeholders can understand the software's performance, known issues, and any potential risks. This nuanced view allows them to make decisions based on the context of their project goals versus the actual outcomes of the testing efforts.

In contrast, completing testing based solely on fixing all defects may not capture the overall quality or readiness for release, especially if some defects are acceptable and do not hinder the product's utility. Successful test case execution does not necessarily guarantee that the software is fit for release, as real-world usage may expose additional issues that weren't caught during testing. Additionally, testing simply concluding based on time and budget constraints does not align with ensuring that quality and necessary information have been adequately addressed, potentially compromising the release decision.
