Learn API Testing That Actually Works in Production

Most testing courses teach you the theory. We show you how real teams catch bugs before they break production systems. Our training comes from engineers who've debugged live APIs serving millions of requests.

What You'll Learn From People Who've Done It

These aren't academic exercises. They're the exact skills our instructors use when they're firefighting production issues at 2 AM.

REST and GraphQL Testing

You'll write tests that validate response structures, handle authentication, and catch edge cases before your users do. We focus on patterns that scale from small APIs to enterprise systems.

Integration Testing Strategies

Learn how to test when your code talks to databases, message queues, and third-party services. We'll show you how to write tests that are reliable without being brittle.

Test Automation Architecture

Build test suites that your team will actually maintain. We cover test organization, data management, and how to make your CI/CD pipeline something people trust instead of ignore.

Performance and Load Testing

Find out when your API will fall over under real-world conditions. You'll learn to design load tests that reveal bottlenecks and how to interpret results that matter to your business.

Contract Testing

When microservices teams can't coordinate deployments, contract testing saves the day. We teach practical approaches to consumer-driven contracts that prevent integration breakage.

Security Testing Fundamentals

Authentication, authorization, injection attacks, and data exposure. You'll learn to spot vulnerabilities before security researchers file bug reports on your public endpoints.

Training Built Around Real Problems We've Solved

Your instructors have worked on systems processing millions of API calls daily. One of them spent three years building testing infrastructure for a fintech company where downtime measured in seconds cost actual money. Another debugged integration failures across 40+ microservices for an e-commerce platform.

Hands-On Projects From Actual Scenarios

You won't build toy applications. Your assignments come from situations we've encountered in production environments. That time authentication tokens expired mid-request? We'll show you how to test for that. The edge case where timezone conversions broke data synchronization? That's in here too.

We structure our curriculum around the problems that keep engineering teams up at night. Each module focuses on a specific type of failure we've seen break production systems.

  • Test APIs that interact with databases, caching layers, and external services
  • Write integration tests that catch configuration issues before deployment
  • Build test data strategies that work with real-world data complexity
  • Debug flaky tests that pass locally but fail in CI environments
  • Set up monitoring and observability for your test infrastructure

How Our Program Works

Foundation Phase

Start with HTTP fundamentals, API design principles, and testing tool selection. We cover the concepts that make everything else make sense. You'll set up your development environment and write your first automated API tests.

Integration Testing Deep Dive

This is where it gets interesting. You'll learn to test complex workflows involving multiple services, handle database state, and manage test data. We show you patterns for testing async operations and event-driven architectures.

Advanced Testing Techniques

Contract testing, performance testing, chaos engineering. These are the skills that separate junior testers from people who can architect testing strategies for large systems. You'll work on projects that simulate real production complexity.

Capstone Project

Build a comprehensive test suite for a microservices application that includes REST APIs, GraphQL endpoints, message queues, and database integrations. Your instructors review your work like they would in a code review at their day jobs.

Learning Format That Fits Your Schedule

We run cohort-based programs where you'll work with other students on group projects. But the coursework is flexible enough to accommodate full-time jobs. Most students spend 10-15 hours per week on coursework.

Your instructors hold office hours twice weekly. And they're responsive on our class discussion channels when you're stuck on something. One instructor, Dagmar Lindström, once helped a student debug a timezone issue at 11 PM because she remembered dealing with the exact same problem at her previous job.

Live Workshops

Interactive sessions where we work through testing challenges together and review real code from projects you're building.

Code Reviews

Get feedback on your test code from engineers who write this stuff professionally. We'll catch issues before they become habits.

Resource Library

Access our collection of testing templates, scripts, and documentation that our instructors use in their daily work.

Community Support

Join a group of people learning the same skills. Past students stick around to help new cohorts troubleshoot problems.

Classes start on a rolling basis, with new cohorts beginning every six weeks. That gives you time to wrap up current projects before diving in. The full program runs for twelve weeks, though some students take longer to complete their capstone work.
