Apex (Salesforce) Test

This area assesses proficiency in writing, structuring, and maintaining robust test classes that validate Apex logic. Candidates must understand @isTest, Test.startTest()/stopTest(), and System.assert for proper coverage and reliability. Debugging skills include using logs, handling exceptions, and interpreting governor limit outputs. Strong testing practices are vital for continuous deployment, ensuring predictable behavior during releases and meeting Salesforce’s mandatory 75% coverage requirement while promoting modular, maintainable code.

This skill focuses on how Salesforce connects and exchanges data with external systems through REST, SOAP, Bulk, or Streaming APIs. Candidates must know when to use each API, handle callouts with HttpRequest and Named Credentials, and design secure, scalable integrations. Understanding authentication flows, error handling, and async patterns is crucial. This ensures developers can create reliable and compliant data flows across platforms while maintaining system performance and resilience.

Customization Best Practices measure understanding of designing scalable, maintainable solutions within Salesforce using both declarative and programmatic tools. This includes when to use custom objects, metadata, or automation tools like Flows and Validation Rules instead of Apex. Candidates demonstrate how to balance configuration versus code, ensuring alignment with Salesforce’s low-code philosophy while delivering flexible, upgrade-safe customizations that support evolving business requirements.

This skill assesses a developer’s foundational understanding of Apex syntax, data types, collections, control structures, and exception handling. It also covers object-oriented principles such as classes, interfaces, inheritance, and access modifiers within the Salesforce context. Mastery of these basics enables developers to write clean, efficient, and maintainable code that respects governor limits and platform conventions. Candidates should demonstrate comprehension of how Apex interacts with the database and Lightning Platform, serving as the backbone for all higher-level Salesforce development skills.

This skill covers querying, manipulating, and optimizing Salesforce data using SOQL and SOSL efficiently and securely. Candidates must know how to write selective queries, avoid governor limit violations, and implement bulk-safe logic. The focus includes handling relationships, index use, and avoiding SOQL injection. Proficiency ensures high-performing and secure data access layers—crucial for maintaining scalability and reliability in data-heavy enterprise environments.

This skill assesses a developer’s ability to design, structure, and optimize triggers following best practices like bulk safety, recursion prevention, and separation of logic into handler classes. It includes understanding automation order of execution, integration with Flows, and using declarative vs programmatic approaches appropriately. Candidates must ensure maintainability and predictability of automated business logic while preventing common pitfalls like mixed DML or redundant process execution.

Asynchronous Apex evaluates understanding of background processing tools like Queueable, Batchable, Future methods, and Scheduled Apex. Candidates demonstrate the ability to handle large data volumes, execute callouts, and optimize performance without exceeding governor limits. Mastery here ensures efficient system design that balances user experience with backend processing needs, especially in high-scale automation, integrations, and data processing tasks that must comply with Salesforce’s execution context and limit framework.

This skill tests awareness of Salesforce’s overall architecture, tools, and deployment ecosystem. Candidates should understand metadata management, environment types (sandbox vs production), CI/CD via SFDX, and secure deployment using change sets or unlocked packages. It also includes how platform features like Custom Metadata Types, Record-Triggered Flows, and WITH SECURITY_ENFORCED align with modern best practices. Proficiency ensures developers design solutions that are maintainable, deployable, and consistent with Salesforce’s 2025 platform standards.

This skill assesses a developer’s ability to write Apex code that runs efficiently within Salesforce’s multi-tenant constraints. It includes understanding governor limits, bulkifying logic, moving SOQL/DML operations outside loops, and leveraging collections for data processing. Mastery ensures the system remains performant at scale, preventing runtime exceptions and enabling enterprise-grade reliability.
