Master Unit Testing Through Real Code

Build reliable software with confidence
Unit testing isn't just about writing tests—it's about understanding how your code behaves under different conditions. Our hands-on programs teach you to think like a quality engineer, spot potential issues before they reach production, and write tests that actually matter.

Testing That Makes Sense

We focus on practical skills that solve real development challenges

Test-Driven Development

Learn to write tests before code—a practice that changes how you think about software design and helps catch issues early in the development cycle.

Mock Objects & Stubs

Master isolation techniques that let you test individual components without depending on databases, APIs, or external services.

Coverage Analysis

Understand what coverage metrics actually tell you and how to use them to improve test quality rather than just hit arbitrary numbers.

Learn By Doing

Our programs start with existing codebases—both clean and messy ones. You'll work with legacy code, refactor for testability, and practice debugging techniques that professional developers use every day.
  • Debug failing tests in real applications
  • Refactor untestable code into testable components
  • Write integration tests for complex workflows
  • Practice continuous integration setup
  • Handle edge cases and error conditions

Why Unit Testing Skills Matter Now

The software industry has changed. Teams ship faster, codebases grow larger, and bugs cost more than ever.
Companies spend significant resources fixing bugs that could have been caught with proper testing. But writing good tests requires a different mindset than just coding features. You need to think about failure modes, understand dependencies, and design tests that remain useful as code evolves.

Our next cohort begins September 2025, designed for developers who want to write more reliable software and understand testing beyond the basics.

The best part about solid testing skills? They make you more confident when making changes. You can refactor aggressively, fix bugs quickly, and add features without worrying about breaking existing functionality. That confidence shows in code reviews and technical discussions.

Learn From Experienced Engineers

Our instructors have debugged production systems, written test suites for million-line codebases, and mentored junior developers through their testing journey.

The hardest part about learning testing is knowing which tests to write. I help students understand the difference between testing for the sake of coverage and testing to prevent real problems.

Good tests tell a story about how your code should behave. When students start thinking of tests as documentation, their whole approach changes—and so does their code quality.
