Postman API Testing

Key Tools (Minimal Mode - 40 tools)

• Workspace: createWorkspace, getWorkspace, getWorkspaces
• Collection: createCollection, getCollection, putCollection, createCollectionRequest, runCollection
• Environment: createEnvironment, getEnvironment, getEnvironments
• Mock: createMock, getMock, publishMock
• Spec: createSpec, getSpec, generateCollection, syncCollectionWithSpec
• Testing: runCollection

Common Workflows

Project Setup

1. Create workspace
2. Create collection with schema
3. Create environment (local/staging/prod)
4. Save IDs to .postman.json

Generate from OpenAPI

1. Create spec with OpenAPI definition
2. Generate collection from spec
3. Sync collection with spec on changes

Automated Testing

1. Get workspaces and collections
2. Run collection with environment
3. Review results and fix errors

Best Practices

• Store workspace/collection/environment IDs in .postman.json
• Use environment variables for different contexts
• Add post-request test scripts for validation
• Run collections before deployment
• Ensure API server is running before tests
