February 2025 Edition: Smarter Code Coverage Strategies for TDD, Expert Takes, and Key Sessions
Hello TDD Enthusiasts,
Hope the last edition helped you mock your dependencies right! This time, let’s talk about code coverage. How much is enough? How do you avoid unnecessary tests?
So without any further ado, let’s get started:
?? Topic of the Month: Is Code Coverage a Vanity Metric?
TDD focuses on writing tests before writing code, ensuring that every piece of logic is backed by a meaningful test. But how do you verify if you’ve covered all the necessary paths? That’s where code coverage comes in. On its own, a high coverage number can be misleading. But when used correctly, it ensures tests aren’t just present, they’re driving quality.
The main problem with achieving high test coverage is that teams often write redundant or low-value tests. These tests don’t necessarily improve software quality but still require time to write, execute, and maintain. Over time, this leads to bloated test suites that slow down development and make automation inefficient.
HyperTest solves this by ensuring that tests focus on what truly matters. Instead of blindly increasing the test count, it optimizes the process to cover critical scenarios efficiently. This means faster, smarter testing without unnecessary overhead. HyperTest can help you:
? Identifies missing test cases by analyzing untested execution paths, reducing gaps in test coverage.
? Generates tests based on real user interactions and traffic patterns, ensuring higher relevance and effectiveness.
? Automatically mocks dependencies like APIs and databases, preventing integration delays in test-driven development.
? Provides detailed insights into untested code areas, helping improve test quality beyond simple coverage metrics.

Bas highlights how delaying test writing leads to inefficient automation. He emphasizes that the solution isn’t just better tests but improving testability from the start as a team effort.
Kent values developers ensuring reliable changes over strictly following a workflow but expects real proof of that responsibility in practice.
John highlights that TDD is one way to capture requirements, design, and implement reliably, but it’s not the only way: what matters is owning the quality of your work.
Florian shares his long-term experience with TDD, emphasizing the importance of writing tests first, keeping them fast, and ensuring they guide design without slowing development.
