TDD with Qt 6 – Episode 3: Test Fixtures & Data-Driven Tests (Qt Test Tutorial)

Welcome to Episode 3 of our Test-Driven Development with Qt 6 series! 🚀

In this session, we’ll go deeper into Qt Test by exploring fixtures and data-driven tests to keep our tests clean, independent, and repeatable.

👉 What you’ll learn in this video:

✅ Using init() and cleanup() for setup and teardown
✅ Why test fixtures help keep code DRY and maintainable
✅ Writing data-driven tests with QTest::addColumn and QTest::newRow
✅ Testing multiple scenarios with minimal code duplication
✅ Ensuring tests are independent and repeatable

Practical demo: Testing Calculator::divide() with multiple inputs, including edge cases like division by zero

This will help you build robust tests for real-world applications while keeping your codebase easy to maintain.
