Static testing is an early phase of testing that focuses on reviewing and analyzing the software's documentation and code without executing the actual program. This type of testing is important because it helps identify potential issues and defects in the application before it enters the actual functionality testing phase.

By reviewing requirements, design documents, and code through techniques such as inspections, reviews, and static code analysis, testers can catch errors early and ensure that the application meets its specifications and quality standards. This early involvement can significantly reduce the cost and effort required for later stages of testing, making the software development process more efficient and effective.

In contrast, validation testing, regression testing, and exploratory testing occur at different phases of the software development lifecycle, often after the application has been developed or partially developed, focusing on functional aspects, validating that the software meets the requirements after changes, or investigating the software in an unstructured way, respectively.
