What is one of the principles of static testing?

One of the principles of static testing is that it involves the examination of documents, which includes analysis and design documents. Static testing is a technique used to identify defects in software without executing the code, relying instead on reviewing artifacts such as requirements, design specifications, and other types of documentation. This process helps to catch potential issues early in the software development lifecycle, before the code is actually run, which can save time and resources later on.

This principle emphasizes the importance of reviewing and verifying the work done during the earlier phases of development to ensure that the project is on the right track, thus significantly contributing to overall quality assurance. Static testing can be performed by various stakeholders, including testers, developers, and analysts, not just developers, and it does not focus on providing complete test coverage of the code, but rather on identifying discrepancies and areas of improvement in documentation and design.
