Explore practical examples of unit test failures caused by race conditions in software development.
When developers talk about flaky tests, the conversation almost always ends up on mocking. The best examples of unit test failures: mocking issues examples usually come from real teams wrestling with brittle, over‑mocked test suites that break every time the wind changes direction. In this guide, we’ll walk through practical, code‑level examples of how mocking goes wrong, why those tests fail, and how to fix them without rewriting your entire test suite. Instead of staying abstract, we’ll look at concrete scenarios from HTTP clients, databases, time‑dependent logic, third‑party APIs, and asynchronous code. These examples of unit test failures: mocking issues examples are written for engineers who already know how to write tests, but are tired of guessing why a supposedly isolated unit test fails only in CI, or only on Tuesdays, or only after a refactor. If that sounds familiar, keep reading — you’ll probably recognize your own code in a few of these stories.
In this article, we will explore common examples of unit test failures caused by incorrect assertions. You'll learn how to identify these issues and ensure your tests are accurate and reliable.
