Your frontend can look perfect while your API silently returns wrong data, leaks user information, or fails under load. We test every endpoint, auth flow, and error state before your users find the problems.
30 minutes · Senior engineer · No commitment
Every aspect of your API — from happy paths to the edge cases that break in production.
Every endpoint tested for correct status codes, response schemas, data types, and business logic correctness.
JWT token validation, OAuth flows, API key security, session management, and unauthorized access attempts.
SQL injection via API, IDOR (broken object-level auth), mass assignment, and sensitive data exposure in responses.
Verify rate limits are enforced correctly and that your API degrades gracefully under high request volumes.
What happens when you send malformed data? Missing fields? Invalid types? We test every error path.
Postman/Newman collections that run in your CI/CD pipeline — automated API regression on every deployment.
We use the right tool for your stack — not just the one we know best.
Comprehensive API collections with environment variables, pre-request scripts, and automated assertions. Newman runs them in CI/CD.
Java-based API testing for Spring Boot and other JVM backends. Fluent DSL for readable, maintainable test suites.
PHPUnit-based API tests for Laravel backends — feature tests, HTTP assertions, and database state validation.
Query/mutation validation, schema testing, resolver authorization, and introspection security for GraphQL APIs.
QA gaps show up as regressions, store rejections, and security findings — usually right before launch.
Manual smoke tests can't keep pace with weekly releases.
Lovable and Cursor prototypes reach staging without auth or edge-case coverage.
Mobile flows break on OS versions QA didn't cover.
Testing in launch week makes fixes expensive and stressful.
Manual, Cypress/Playwright, API, k6 performance, and security testing.
We harden vibe-coded apps before production traffic.
Code review from seniors who build Laravel, React, and Flutter daily.
Go/no-go reports with severity-rated bugs — not vague pass/fail.
OWASP-focused web and API tests; pen testing available.
Read-only repos; anonymized test data where required.
“What a 70-engineer team could not deliver, a small senior team at GreeLogix shipped. The app went from stuck to live across mobile, web, and backend.”
At-a-glance scope, pricing tiers, delivery timelines, engineering tradeoffs, and decision criteria for technical founders and product leaders.
Software QA and technical audit services cover manual and automated testing, performance and security checks, and senior engineer code review — especially for AI-generated or inherited codebases before production launch.
Pricing depends on scope, integrations, and timeline. GreeLogix provides transparent fixed-milestone quotes after discovery, with flexible models for one-off audits, sprint retainers, or dedicated engineers.
Need to model sprint hours and coverage? Use our QA estimation calculator.
Smoke audit: 1 week. Full regression cycle: ongoing per sprint. Deep code audit: 5–7 business days. Phases: Strategy (Week 1); Execution (Per sprint); Automation (Parallel).
Compare delivery models, cost profiles, and engineering tradeoffs before committing resources.
| Option / Approach | Best When | Primary Tradeoff / Risk | Recommended Fit |
|---|---|---|---|
| Developer-only testing | Early prototype with no paying users yet | Developers tend to test happy paths; misses subtle regression side effects, UX edge cases, and cross-browser quirks. | Early pre-revenue prototypes |
| Crowdtesting platforms | One-off device coverage without domain context | Fragmented bug reports without codebase context, inconsistent reproducibility, and zero sprint continuity. | One-off device compatibility checks |
| Automated scanning only | Known stack with mature CI; catches syntax not workflow bugs | Catches syntax and linting issues but remains completely blind to workflow breakdowns and complex business logic errors. | Baseline CI static analysis |
| GreeLogix Pod | You need production release confidence, automated regression suites, and senior QA engineers embedded in your sprint. | Requires active product owner for weekly sprint reviews and scope alignment. | Production & Scaling (Recommended) |

Answers to the buyer questions we hear most before a project starts.
API testing covers endpoint validation (correct responses, status codes, data schemas), authentication testing (JWT, OAuth, API keys), rate limiting, error handling, response time benchmarks, and security checks like injection attacks and broken object-level authorization.
Yes. We test GraphQL APIs for query/mutation correctness, schema validation, authorization on resolvers, N+1 query issues, and introspection security. We use Postman and custom tooling for GraphQL-specific testing.
Yes. We build Postman/Newman collections that run in CI/CD pipelines, giving you automated API regression testing on every deployment. We also build REST Assured suites for Java-based backends.
We review your OpenAPI/Swagger spec or existing documentation to map every endpoint and expected behavior.
Postman collection built with positive tests, negative tests, auth tests, and edge cases for every endpoint.
Security-focused tests run alongside basic load tests to identify auth bypasses and performance bottlenecks.
Newman configured in your pipeline. Every deployment triggers the full API test suite automatically.
Share your API documentation or Postman collection and we'll scope your testing engagement.
