What is a recommended practice for code usability in GUnit?

Creating test helper classes or functions is a recommended practice for code usability in GUnit because it promotes modularity and reusability within the test suite. Helper classes or functions allow you to encapsulate common test setups, assertions, or utility methods that can be reused across multiple test cases. This reduces redundancy and can make tests easier to read and maintain, as each helper function can be named meaningfully to reflect its purpose. Good organization of test code through helper methods directs focus on the actual business logic being tested rather than the setup details, facilitating better collaboration among developers and testers.

In contrast, implementing complex UI tests could lead to overly complicated and fragile tests that are hard to maintain and understand. Running tests without any structure would result in disorganized testing practices, making it difficult to identify issues or track results. Ignoring repeatable functions would counteract the benefits of reusability, leading to duplicated code, which can complicate maintenance and increase the chances of errors. Using helper methods or classes ensures that test code remains clean, efficient, and easy to navigate.
