5 components of a good maintenance strategy:
1. Establishing connections with UI/UX
Maintaining an IT project involves close cooperation with specialists of different profiles, particularly those working on the user interface (UI) and user experience (UX). Developers who handle the interface play a significant role in the project, as changes are often made to the user interface to make it more convenient, relevant, and understandable. However, these changes can impact the test suite, making test automation maintenance a critical consideration.
Focusing on the location coordinates of an interface object, HTML map, or dynamic identifier can make your tests overly sensitive to changes in the interface. This sensitivity often leads to frequent test failures whenever minor UI adjustments are made, increasing maintenance efforts. To mitigate this issue, forming a static naming convention is essential. This approach helps maintain the stability of your test automation suite amidst ongoing UI changes.
Here are several strategies to enhance test automation maintenance in the context of UI/UX changes:
Implement Static Naming Conventions: Using static identifiers, such as a static QA id in your code, reduces the impact of design changes on test suites. This practice is similar to how programmers ensure their code is easily transferable and understandable. Static naming conventions make it easier for automated tests to locate and interact with UI elements consistently, even as the UI evolves.
Collaboration with UI/UX Teams: Establishing strong communication channels between QA and UI/UX teams is vital. Regular updates and meetings ensure that testers are aware of upcoming changes, allowing them to adjust test scripts proactively. This collaborative approach is a key component of a robust test automation strategy.
Use of Page Object Model (POM): The Page Object Model is a design pattern that enhances test automation maintenance by separating the test logic from the UI representation. By creating an object repository for UI elements, POM allows changes to be made in one place, reducing the maintenance effort when UI changes occur.

For instance, unit tests do not require extensive automation costs and can be executed extremely fast, contributing significantly to an effective test automation strategy.
Modular Structure in Test Automation
Using a modular structure is highly beneficial when it is necessary to remove the dependency of one test on another. This approach positively impacts the quality of service, as it allows activities to be performed simultaneously or distributed across different teams. Additionally, reusable modules can save time and resources, making the overall process more efficient.
However, what if you need to work with complex and lengthy scripts? In such cases, it makes sense to implement test suites that can be used repeatedly. These suites should be designed to handle comprehensive scenarios while maintaining simplicity and clarity. This practice not only improves test automation maintenance but also enhances the robustness of the test automation strategy.
Managing Complex Test Cases
When dealing with complex test cases, it is crucial to pay attention to their design. Complicated test cases increase the time spent on support and the probability of failure. If you encounter a test case with many steps, it’s best to split it into two or more simpler cases. Each test case should ideally work with only one function or action. High complexity almost always leads to stability problems, making maintenance more challenging.
Strategies for Simplifying Test Automation
Focus on Low-Level Tests: Prioritize low-level tests such as unit tests, which are fast and cost-effective. These tests provide a solid foundation for your automation suite and are easier to maintain.
