Best Practices for Salesforce Code Review | Quality and Performance

Introduction to Salesforce Code Review:

Salesforce development, where customization is key to success, the importance of thorough Salesforce Code Review cannot be overstated. It’s not just about ensuring the code works as intended; it’s also about guaranteeing its quality, performance, and security. In this comprehensive guide, we’ll delve into the best practices for conducting Salesforce code reviews, focusing on both quality and performance aspects.

1. Establish Clear Guidelines and Standards

Every successful Salesforce Code Review process begins with establishing clear guidelines and standards. These standards should cover coding conventions, naming conventions, architecture patterns, and performance considerations specific to Salesforce development. By documenting these standards, teams ensure consistency and reduce ambiguity during code reviews.

2. Use Version Control

Utilizing version control systems like Git is fundamental for managing changes to the Salesforce codebase effectively. Following branching strategies such as GitFlow helps isolate features or fixes, making it easier to review changes incrementally. Version control also enables tracking modifications, facilitates collaboration, and provides a safety net for rollbacks if needed.

3. Leverage Automated Tools

Integrating automated tools into the development workflow is crucial for identifying potential issues before Salesforce Code Review. Tools like Salesforce CLI, PMD, and CodeScan can perform static code analysis, syntax validation, and security scanning, reducing manual effort and catching common mistakes early in the development cycle. Additionally, incorporating continuous integration (CI) pipelines automates the execution of tests and checks against every code change.

4. Prioritize Readability and Maintainability

Readable and maintainable code is essential for long-term sustainability and collaboration within development teams. During Salesforce Code Review, emphasis should be placed on readability by ensuring meaningful variable names, clear comments, and consistent formatting. Encouraging modular design principles, such as separation of concerns and reusable components, simplifies understanding and future modifications.

5. Review for Performance Considerations

Optimizing code for performance is critical in Salesforce development to deliver a responsive user experience and minimize resource consumption. During code review, evaluate queries, loops, and data manipulation operations for efficiency. Avoid inefficient practices like nested loops, redundant queries, or excessive data processing, as these can lead to performance bottlenecks, particularly with large datasets.

6. Validate Governor Limits Compliance

Salesforce imposes governor limits to ensure fair resource allocation and prevent abuse of shared infrastructure. Salesforce Code Review, validate that the proposed changes comply with these limits, such as SOQL queries, DML operations, CPU time, and heap size. Identify potential issues like query bulkification, bulk DML processing, and efficient iteration techniques to stay within governor limits and prevent runtime exceptions.

7. Security Review

Security is paramount in Salesforce development, especially when dealing with sensitive data and customer information. Conduct a thorough security review during code inspection to identify vulnerabilities, such as SOQL injection, XSS (Cross-Site Scripting), CRUD/FLS (Create, Read, Update, Delete/Field-Level Security) violations, and insecure API integrations. Apply the principle of least privilege and follow Salesforce security best practices, including data encryption, access controls, and secure coding techniques.

8. Validate Business Logic

Ensure that the code aligns with the intended business requirements and logic defined in the functional specifications. Verify that the implementation accurately reflects the expected behavior, handles edge cases, and gracefully handles error conditions. Collaborate closely with stakeholders and subject matter experts to validate the business logic during code review, preventing misunderstandings or deviations from the intended functionality.

9. Assess Test Coverage and Quality

Code review should not only focus on the code itself but also on the accompanying tests that validate its behavior. Assess the adequacy of test coverage, ensuring that critical paths and edge cases are covered by unit tests, integration tests, and system tests. Evaluate the quality of test cases by considering assertions, data setup, and test isolation. Encourage developers to write meaningful, self-descriptive test methods that enhance understanding and maintainability.

10. Provide Constructive Feedback

Code review is a collaborative process aimed at improving the overall quality of the codebase and fostering continuous learning within the team. Provide constructive feedback to developers based on objective criteria and identified issues. Offer suggestions for improvement, alternative approaches, or references to relevant documentation or best practices. Encourage open communication, respect diverse perspectives, and cultivate a culture of continuous improvement.

11. Foster Knowledge Sharing

Salesforce Code Review as an opportunity for knowledge sharing and skill development among team members. Encourage developers to explain their design decisions, share insights, and learn from each other’s expertise. Conduct regular knowledge-sharing sessions, code walkthroughs, or lunch-and-learn sessions to discuss interesting solutions, lessons learned, or emerging technologies. By fostering a culture of collaboration and shared learning, teams can collectively raise their proficiency and effectiveness in Salesforce development.

12. Iterate and Refine the Process

Continuous improvement is key to maintaining an effective Salesforce Code Review process over time. Periodically evaluate the effectiveness of existing practices, gather feedback from team members, and identify areas for refinement. Experiment with new tools, techniques, or methodologies that could enhance productivity, quality, or performance. Iterate on the code review process iteratively, incorporating lessons learned and adapting to evolving project requirements or industry best practices.


Salesforce code review is indispensable for ensuring the quality, performance, and security of customizations. By adhering to best practices such as establishing clear guidelines, leveraging automation, prioritizing readability and maintainability, and validating performance and security considerations, teams can enhance the overall effectiveness of their development process. Through constructive feedback, knowledge sharing, and continuous improvement, code review becomes not just a validation step but a collaborative endeavor to deliver exceptional Salesforce solutions that meet business objectives and exceed user expectations.
