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

The choice of a static analysis tool is particularly significant in ensuring higher quality in the code to be reviewed. Static analysis tools examine the source code without executing it, identifying potential issues such as coding standard violations, security vulnerabilities, and potential bugs. By analyzing the code early in the development lifecycle, these tools enable developers to address issues proactively, leading to cleaner, more reliable code before it even reaches the review phase.

In contrast, review tools primarily facilitate the manual review process by providing platforms for collaboration and discussion among team members but do not inherently improve the quality of the code. Test execution tools are designed to execute tests against the software and gather results, focusing more on validating the product after development. Test design tools assist in crafting test cases but do not directly address the quality of the code being reviewed. Therefore, static analysis tools play a crucial role in elevating code quality through early detection and fixation of problems.
