# Dynamo Unit Testing ## When to use - Writing new test methods or test classes for Dynamo components - Setting up test infrastructure (base classes, setup/teardown) - Testing nodes, workspaces, or UI components - Working with .dyn test files or sample graphs - Reviewing existing tests for quality and patterns - Debugging test failures or flaky tests ## When not to use - General coding questions -- use dynamo-dotnet-expert instead - Architecture questions -- use dynamo-onboarding instead - PR descriptions -- use dynamo-pr-description instead ## Inputs expected Test requirements, failing functionality to test, existing code to cover, or test code to review. ## Output format Complete test classes with proper setup, test methods using Dynamo patterns, and explanations of testing approach. --- ## Workflow > 🚀 **Quick Start**: [test-patterns.md](./assets/test-patterns.md) has ready-to-use templates ### 1. Choose Your Base Class Select the appropriate test base class based on what you're testing: - **UnitTestBase** - Utilities, algorithms, no Dynamo model needed - **DynamoModelTestBase** - Nodes, workspaces, commands (most common) - **DSEvaluationUnitTestBase** - DesignScript expression evaluation ### 2. Apply Testing Standards - [Dynamo Coding Standards](https://github.com/DynamoDS/Dynamo/wiki/Coding-Standards) - [Dynamo Naming Standards](https://github.com/DynamoDS/Dynamo/wiki/Naming-Standards) ### 3. Write Focused Tests One behavior per test, descriptive names, Arrange-Act-Assert structure. ## Testing Principles - **NUnit only** - Use NUnit framework exclusively (never xUnit/MSTest) - **One behavior per test** - Each test validates exactly one scenario - **Pragmatic .dyn testing** - .dyn file tests allowed in unit categories for focused functionality ## Documentation **Assets & References:** - **[test-patterns.md](./assets/test-patterns.md)** - Base classes, code templates, common scenarios, complete examples - **[quality-checklist.md](./references/quality-checklist.md)** - Quality guidelines, anti-patterns, best practices **Related Skills:** - dynamo-dotnet-expert - dynamo-onboarding
