Automated QA as the norm in 2025

Automated QA (Quality Assurance) refers to the use of software tools to automatically execute predefined tests on a codebase, ensuring that the software behaves as expected. Unlike manual testing, which requires human intervention, automated QA runs scripts that simulate user interactions, API calls, or internal processes to validate functionality, performance, and security. These automated tests are often integrated into continuous integration (CI) and continuous delivery (CD) pipelines to catch issues early in the development cycle.

By reducing the need for repetitive manual tests, automated QA saves time, minimizes human error, and enhances test coverage across different environments. While there are significant benefits, such as early bug detection and faster release cycles, we will explore these in detail in the next chapter.

As an Azure-focused development company, we will be highlighting Azure tools and services throughout this guide to demonstrate how they can streamline and optimize automated testing.

The evolution of software testing: from manual to automated QA

In the early days of software development, testing was entirely manual, with QA engineers meticulously executing test cases by hand to ensure software met requirements. While this approach offered a detailed, human-centric perspective, it was time-consuming, error-prone, and struggled to keep pace with the increasing complexity of modern applications.

The introduction of automated QA revolutionized the process. Automation allowed for repetitive and large-scale tests to be executed faster and with higher accuracy, supporting agile methodologies and CI/CD pipelines. Over the years, advancements in testing tools, frameworks, and integration capabilities have solidified automated testing as a cornerstone of modern QA practices.

By 2023, this shift was evident, with 77% of companies adopting automated software testing to enhance efficiency and accuracy in their development processes. While manual testing still plays a vital role in exploratory testing and areas requiring human judgment, automation has become the backbone of scalable, reliable software testing.

Best practices for implementing automated QA

Implementing automated QA is a strategic move that can greatly enhance your testing process, but without proper planning and execution, it can lead to wasted effort and suboptimal results. Here are 10 hands-on best practices aimed at helping teams avoid common pitfalls, save time, and maximize ROI.

1. Prioritize test cases for automation

Not all tests are worth automating. Focus on:

• Repetitive tests, such as regression and smoke tests.
• High-risk areas prone to frequent failures.
• Tests that need to run across multiple platforms or configurations. Avoid automating exploratory, ad-hoc, or one-off tests where human judgment is critical.

2. Start small and scale gradually

Begin with a manageable scope:

• Automate critical paths or core functionalities first.
• Prove the value of automation with quick wins, then scale to broader test coverage. Rushing to automate everything at once can lead to poorly maintained scripts and wasted resources.

3. Choose the right tools for your needs

Select tools based on:

• Project requirements (e.g., mobile vs. web, API vs. UI).
• Team expertise (open-source vs. proprietary tools).
• Ecosystem integration (compatibility with CI/CD pipelines or cloud platforms like Azure DevOps). For example, Selenium for web automation or Appium for mobile apps are solid choices, but ensure the team has or develops the skills to use them effectively.

4. Maintain clean and modular test scripts

Structure test scripts with:

• Reusable components for shared functionalities (e.g., login scripts).
• Separation of test logic and data (use data-driven testing where possible). Clean, modular scripts make maintenance easier and reduce duplication of effort.

5. Integrate automation into CI/CD pipelines

Automated QA is most effective when integrated into CI/CD workflows:

• Trigger tests automatically on code commits, merges, or deployments.
• Include fast tests (e.g., unit, smoke) early in the pipeline and resource-intensive tests (e.g., performance) later. This ensures rapid feedback and continuous quality checks.

6. Use version control for test scripts

Store your test scripts in version control systems (e.g., Git) alongside your application code. This:

• Ensures collaboration among QA and development teams.
• Provides traceability and versioning for test updates.

7. Regularly review and refactor test suites

Automated tests aren’t “set it and forget it.” Regularly:

• Remove redundant or outdated tests.
• Update scripts to align with codebase changes.
• Monitor flaky tests (those that fail intermittently) and address root causes. This keeps your test suite relevant, reliable, and efficient.

8. Monitor test results and metrics

Track metrics such as:

• Test pass/fail rates.
• Execution time.
• Coverage percentage. Use dashboards or reporting tools to analyze trends and identify areas for improvement. Ignoring results can lead to undetected failures or wasted automation efforts.

9. Plan for scalability and parallel execution

Design your automation framework to:

• Run tests in parallel to speed up execution.
• Support scaling across multiple environments (e.g., browsers, operating systems). Cloud-based testing platforms like Azure Test Plans or BrowserStack are excellent for handling scalability needs.

10. Invest in team training and collaboration

Automation success depends on the team:

• Train testers to write effective scripts and use tools confidently.
• Encourage collaboration between developers and QA engineers to ensure tests align with the application’s architecture. Cross-functional collaboration ensures both quality and speed.

Automated QA is a long-term investment. By adopting these best practices, you can avoid common mistakes, save resources, and deliver high-quality software faster. Remember, the goal is not just to automate but to ensure that automation adds tangible value to your testing and development processes.
