Learn to balance test coverage with development velocity while protecting the critical operations that power your Content Operating System. Establish automated testing strategies, document business requirements in executable code, and enable confident iteration. From validation logic to React components, develop an intentional testing strategy that ensures reliability and enables you to ship Studio changes with confidence.
1. Why Testing Matters for Studio Development
Testing isn't just quality assurance—it's strategic infrastructure that protects your business logic and enables rapid iteration. Understand how tests document requirements in executable code, provide confidence before changes reach content editors, and free your team to move faster. Learn what makes Studio customizations worth testing and how to think about testing as an investment in long-term velocity.
2. Setting Up Your Testing Environment
Configure Vitest as your testing framework and integrate it into your Studio development workflow. Set up test environments for both monorepo and single-app configurations, understand how testing fits into your build process, and write your first test. Learn the fundamentals of test structure, assertions, and organizing test files alongside the code they verify.
3. Testing Validation and Access Control
Start with the simplest testing scenario: functions with no external dependencies or side effects. Test access control logic that determines who can edit fields, validation functions that enforce business rules, and utility functions that transform data. These isolated functions are straightforward to test and often contain critical business logic that protects content quality across your organization.
4. Testing Stateful Studio Logic
Test validation functions that query your Content Lake to verify business rules across documents. Learn to mock the Sanity client to create controlled test scenarios, build reusable test fixtures that simplify setup, and verify async validation logic that prevents invalid content states. Understand how to test functions that depend on external data without requiring a populated dataset.
5. Testing Studio React Components
Test custom input components that render UI, use Studio hooks, and handle user interactions. Configure a browser-like test environment with React Testing Library, create provider fixtures that supply Studio context, and verify component behavior through simulated user actions. Learn what aspects of components are worth testing and how to balance thorough coverage with maintainable tests.
6. Continuous Integration and Test Strategy
Move tests from local development into CI pipelines that verify changes before they reach production. Configure automated test runs on pull requests, report test results directly in GitHub, and develop a strategic framework for deciding what to test. Learn to prioritize test coverage based on business impact, complexity, and change frequency—balancing protection with development velocity.
7. Tests as Content Operating System Infrastructure
Tests aren't overhead—they're strategic infrastructure that enables confident scaling of your Content Operating System. Comprehensive test coverage protects critical operations as your Studio grows, documents business requirements for future developers, and creates the safety net that allows your team to iterate rapidly. Learn to view testing as a foundational investment that compounds in value over time.
