2. The Importance of Unit Testing in Software Development

Unit testing, a crucial component of software development, is a process that validates the functionality of separate units within a software system. It is typically performed by developers themselves, following best practices and techniques that ensure each unit is tested in isolation. This approach allows for early identification and rectification of bugs or issues.

Unit testing significantly contributes to defect detection and prevention during the development process, enhancing the reliability and efficiency of the final software product. It facilitates improved design and promotes effective code refactoring.

A developer's experience with unit testing can be transformative. For example, a developer, initially skeptical about unit tests, was assigned to a unit test project. The project involved running tests in the build pipeline, which consistently succeeded, leading to an initial impression that the process was redundant. However, after a year, the tests began to fail, revealing a severe error. The issue was found to be in the test framework itself, not in the code being tested.

This experience altered the developer's perception of unit tests, leading to the expansion of the test project. Achieving 100% test coverage of a crucial library was instrumental in averting a potential disaster when a code modification introduced a critical bug.

In the face of a bug, the developer learned to ask three critical questions: "Have I made this error elsewhere?" "What happens when I fix the bug?" and "How can I change my ways to make this bug impossible?" This approach led to the discovery of multiple instances of the same issue throughout the codebase, which were subsequently fixed.

Unit testing is a valuable tool for ensuring that an application behaves as expected and for quickly identifying defects. It involves automated code that invokes a unit of work in a separate piece of code in the application and checks whether the unit of work passes or fails based on the expected behavior.

Unit tests are typically written using a unit testing framework. This allows for efficient test writing and rapid execution. The naming conventions for unit tests are crucial for clarifying the purpose of the test, particularly for new developers or large teams with many contributors to the codebase.

Unit tests should be granular and make a single assertion. This makes it easier to understand why a test is failing when testing multiple outcomes in a single test. They should be repeatable and provide consistent results, meaning that running a test multiple times should yield the same result each time.

Unit tests serve as implicit code documentation, helping new developers understand the codebase. They save time for developers by catching defects early and save businesses money by reducing the hours spent on debugging. Crafting valuable unit tests requires time, research, and the implementation of patterns and conventions. It is essential to continuously improve unit tests and not be solely focused on the underlying logic.

Unit tests are instrumental in ensuring code correctness and serve as an indicator when the implementation or behavior of the code changes. They consider different paths and scenarios in the code and ensure that all expected behaviors are tested. They are valuable in terms of correctness, time-saving, and code documentation. Therefore, it is crucial to invest time in crafting valuable tests

Prioritizing the most critical tests and ensuring they are up-to-date is equally important.

In the case of legacy code, writing unit tests for the existing codebase can help identify bugs or issues and provide a safety net for future changes. Automated regression testing, where a suite of tests is created to ensure existing functionality remains unaffected when changes are made to the codebase, can be a beneficial strategy. Refactoring the code to make it more testable, by restructuring it to separate concerns, can also aid in writing unit tests for legacy code.

For instance, during a "sustainability week" at Busbud, a collective effort was made to address maintenance tasks and pay off technical debt. The initiative involved cleaning up database tests in the codebase, consisting of roughly 5200 integrated tests. Although the plan hit a roadblock, the experience underlined the importance of having a clear goal, timeboxing, being unafraid to start over, and knowing when to stop.

While working on legacy code can be challenging, a series of refactoring steps rather than a single fix can help. Automated tests, which serve as a safety net for changes, can be a valuable addition to this process. The concept of the test pyramid, advocating for a large number of unit tests, a reasonable number of integration tests, and a few UI or end-to-end tests, can provide a robust framework for test coverage.

Dependency injection can play a key role in decoupling tightly coupled code, thus making it easier to write unit tests. Conversations with developers who have previously worked with the code can offer valuable insights. Additionally, management support is vital for effectively tackling legacy code.

Tools like logging, monitoring, and alerts are indispensable for maintaining and troubleshooting legacy code. Progress can be measured through code coverage, static code analysis, and team conventions. Automating deployments and establishing procedures for bug fixing and releases can streamline the development process.
