Quality Engineering Best Practices Balancing Speed, Quality, and Precision for Digital App


In today’s business world, where customers are at the centre, people expect high-quality mobile and web applications. Users want their apps to work smoothly, be easy to use, and have quick response time. To keep up with these expectations, companies need to adopt strong quality engineering practices that maintain a balance between speed, quality, and precision.

This blog post talks about the best practices for App testing, focusing on important strategies like shift-left approach, automation testing, API testing, and QA processes. We’ll share ways to achieve both speed and quality during the product development lifecycle. We’ll also discuss how artificial intelligence (AI) can help speed up the testing cycle.

Top 10 Best Practices for Digital App Testing

1. Shift-Left Strategy

This is the most used buzz word in the App Testing world. Start testing your applications early in the development process. Involve your quality assurance (QA) teams when gathering requirements and designing your application. This helps catch possible problems early on, which means fewer mistakes to fix later in the process, ultimately saving effort and time.

2. Automation Testing

If we want to maintain the speed and precision of product quality then Automation is the key aspect. Implement automation testing to streamline repetitive tasks and accelerate the testing process. Leverage tools such as Selenium, Appium, or Cypress to automate regression testing, UI testing, and performance testing, freeing up valuable time for QA teams to focus on more complex test scenarios. You can even try to use Pcloudy’s codeless test automation tool to accelerate your testing efforts. Come No code automation tools available in the market enables teams and testers to easily implement automation into their ADLC.

3. API Testing

Focus on testing APIs to make sure that your backend services work well and integrate smoothly. By testing APIs for their functionality, reliability, security, and performance, a great user experience can be ensured.

There are many tools and libraries available in the market to efficiently test the APIs along with Integration and Unit tests. Tools like Postman or SoapUI can help in testing endpoints, payloads, and response times to make sure everything is working as expected.

4. Continuous Integration and Continuous Deployment (CI/CD):

One of the best ways to manage the release pipelines is by adopting automation in CI/CD. Make your code changes deliver faster and more reliably by using CI/CD pipelines. These pipelines help you automate building, testing, and deploying your code, so you don’t have to do everything manually. This speeds up the release cycles and keeps the code quality high.

CI/CD pipeline

Here’s a simple explanation: Think of a shopping app. When a developer makes a change, like adding a new payment method, a CI/CD pipeline checks if everything works smoothly. If it does, the updated app is quickly sent out to users through various app distribution channels or platforms.

5. Test Data Management

  • Make sure you have good test data management practices so that your tests are always clean, consistent, and have useful data to work with. Here are some ways to achieve this:
    • Use data masking to hide sensitive information, like replacing real names with fake ones.
    • Generate synthetic data to create realistic test scenarios without using real user data. You can manage this test data using common formats like Excel, CSV, or JSON files.

For example, if you were testing a banking app, you could use synthetic test data generation to create fake user accounts with different balances, transactions, and other details. This way, you can test the app without compromising real financial information and maintain data security.

6. Performance Testing

  • Check your digital app’s performance by performing different kinds of tests. This will help you see how well your app works when many people use it at the same time. Here are three types of tests you can perform:

    • Load testing: Observe your application’s behaviour under high user loads.
    • Stress testing: Assess your application’s capability under extreme usage scenarios.

These tests help you find areas where your app might slow down or have problems. By fixing these issues, you can make your app work smoothly and quickly for everyone during the peak times and festive seasons

7. Security Testing

Incorporate security testing into the QA process to identify and mitigate potential vulnerabilities and security risks.

Perform static and dynamic code analysis

Perform static and dynamic code analysis, penetration testing, and vulnerability scanning to safeguard against security threats and data breaches.

8. UI/ (UX) Testing

Give high importance to UX testing to guarantee that your digital applications align with end-users’ expectations and preferences.

Perform usability, accessibility, and A/B testing to collect feedback and enhance the user experience. There are many libraries available in the market to efficiently test the UI using test automation.

9. Test Environment Management

Set up and sustain well-organised test environments that closely resemble production setups to guarantee the precision and dependability of test outcomes. Utilise containerization, virtualization, or cloud-based options to build separate testing environments that can be effortlessly set up and expanded.

10. Metrics and Reporting

Outline essential performance indicators (KPIs) and measurements to gauge the efficiency and effectiveness of the QA process. Keep an eye on metrics like test coverage, defect density, and test execution times to highlight areas needing enhancement and to monitor progress over time.

Maintaining Speed and Quality

To maintain both speed and quality throughout the product development lifecycle, organisations must adopt a holistic approach that encompasses people, processes, and technology:

  1. Foster a Culture of Quality

    Cultivate a culture of quality within the organisation by emphasising the importance of QA practices, collaboration, and continuous improvement. Encourage open communication, knowledge sharing, and a shared commitment to deliver high-quality products.

  2. Agile and Lean Practices

    Adopt agile and lean methodologies to encourage iterative development, swift feedback loops, and ongoing enhancement. Dissolve barriers between development, QA, and operations teams, promoting teamwork and shared objectives.

  3. Prioritise and Optimise

    Arrange testing efforts according to risk, business significance, and customer benefit, concentrating on vital product success factors. Streamline testing procedures and workflows to cut down on waste, shorten cycle times, and enhance effectiveness.

  4. Continuous Learning and Adaptation

    Encourage a culture of ongoing learning and adaptability, motivating QA teams to keep up with new trends, technologies, and best practices. Invest in training, upskilling, and career development programs to empower team members to grow in their positions.

  5. Implement AI-Powered Testing

     To speed up and improve your testing process, consider using artificial intelligence (AI) and machine learning (ML) tools and techniques.

These advanced technologies can help generate test cases, predict issues, detect unusual behaviour, and analyse test results. By identifying patterns and potential risks, AI-powered tools can significantly enhance your testing efforts and help you deliver better mobile and web applications.


To succeed in the competitive digital world, companies must focus on quality engineering practices to deliver top-notch mobile and web applications that meet user needs. By using strategies like shift-left approach, automation testing, API testing, and strong QA processes, companies can find a balance between speed, quality, and precision. Also, by making quality a priority and using AI-powered testing tools, companies can keep both speed and quality high throughout the product development process. By constantly working to improve quality engineering practices, companies can handle the challenges of modern app development and become leaders in their fields. This focus on quality will help drive innovation and provide the best value to customers in the competitive world of apps and app development.
