Testing for your TypeScript project
Expert testing for TypeScript applications. We find and fix TypeScript-specific bugs and performance issues that affect production apps. From $19.
TypeScript testing issues we find
Common testing problems specific to TypeScript applications.
Excessive use of 'any' type
AI tools use 'any' to bypass type errors instead of defining proper types, removing all the safety benefits TypeScript provides.
Missing strict mode
tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.
Type assertions instead of type guards
Using 'as' casts to force types instead of runtime checks, causing crashes when data doesn't match the asserted type.
Incorrect generic implementations
Overly complex or incorrect generic types that confuse rather than help, making the code harder to maintain.
Inconsistent error types
Errors caught as 'unknown' or 'any' without proper narrowing, leading to unsafe property access on error objects.
Unused exports and dead code
Exported functions, types, and variables that are never imported — increasing bundle size and code complexity.
What our TypeScript 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.
