Which type of tool can help ensure higher quality of the code to be reviewed?

A static analysis tool is designed to analyze source code before it is executed. These tools automatically examine the code for potential errors, coding standard violations, security vulnerabilities, and other quality issues. By analyzing the code statically, before any testing or execution occurs, they help developers identify and correct issues early in the development process. This proactive approach ensures that the code adheres to quality standards, which contributes significantly to the overall quality of the software being developed.

In contrast, other tools such as review tools focus on facilitating manual code reviews, test execution tools are used to automate the running of tests on the software, and test design tools assist in creating test cases. While all of these tools play essential roles in the software development and testing lifecycle, they do not specifically target the code quality assessment in the same direct manner as static analysis tools.
