What do code reviews help achieve in QA?

Code reviews play a crucial role in the Quality Assurance process by primarily focusing on identifying defects early and ensuring adherence to coding standards. Engaging in code reviews allows team members to scrutinize each other’s code for potential issues, which helps catch defects before the code is deployed or integrated into the larger system. This early detection significantly reduces the cost and effort associated with fixing bugs later in the development cycle.

Moreover, code reviews also ensure that coding standards are maintained across the team. Adhering to established guidelines contributes to the readability and maintainability of the code, making it easier for team members to collaborate and for future developers to understand the codebase. When coding standards are enforced through peer review, it fosters consistency and quality in the code produced, enhancing overall software reliability.

While the other options touch upon different benefits, they do not directly represent the primary purpose and significant advantages of code reviews in the QA process.
