In Salesforce development, the practice of re-running tests after making changes to existing code or configurations to verify that updates have not broken previously working functionality.
Real-World Example
When the IT director at Vertex Global needs to streamline operations, they turn to Regression Testing to scale their operations using the Salesforce platform. Regression Testing gives them the infrastructure and tools needed to support new business requirements, handle increased data volumes, and serve a growing user base without compromising performance.
Why Regression Testing Matters
In Salesforce development, Regression Testing is the practice of re-running tests after making changes to existing code or configurations to verify that updates have not broken previously working functionality. Regression tests catch unintended side effects where a change to one area breaks something elsewhere, which is a common source of production incidents.
Regression testing is foundational to safe Salesforce change management. Without regression tests, every change creates risk because there's no systematic way to verify existing functionality still works. With regression tests, teams can make changes confidently knowing that if something breaks, tests will catch it. Mature teams invest in automated regression test suites covering their critical business processes, running them as part of CI/CD pipelines.
How Organizations Use Regression Testing
- •Quantum Labs — Maintains automated regression test suites running in CI/CD pipelines before any production deployment.
- •TerraForm Tech — Treats regression testing as essential infrastructure for safe change management.
- •CodeBridge — Builds regression tests for critical business processes, catching incidents before they reach production.
