Testing for your NestJS project
Expert testing for NestJS applications. We find and fix NestJS-specific bugs and performance issues that affect production apps. From $19.
NestJS testing issues we find
Common testing problems specific to NestJS applications.
Circular dependency issues
Modules importing each other in cycles, causing runtime errors or undefined injections that only surface in production.
Missing exception filters
No global or controller-level exception filters, leaking internal stack traces and database errors to API consumers.
Inefficient module structure
Everything in a single module or deeply nested modules with improper exports, making the app hard to test and slow to bootstrap.
What our NestJS testing covers
Unit tests
Tests for individual functions, utilities, and business logic. Catch bugs at the smallest level.
Component tests
Tests for React components — rendering, user interactions, state changes, and edge cases.
Integration tests
Tests for API endpoints, database operations, and multi-step workflows.
End-to-end tests
Full user flow tests that simulate real user behavior — signup, purchase, and critical paths.
Test infrastructure
Setting up Jest, Vitest, Playwright, or Cypress with proper configuration and CI integration.
CI/CD integration
Running tests automatically on every push so broken code never reaches production.
