QA Automation: Best Practices for Effective Testing

Quality assurance (QA) is crucial to web development services since it guarantees the delivery of trustworthy and functional websites and applications. With the complexity of cross-browser testing and other digital solutions growing, it is now essential to implement testing methodologies.

This article discusses the value of quality assurance (QA) in web development and provides tactics for preserving quality throughout the whole process.

When to Implement QA Automation Testing

  • Repetitive Tests: Automating repetitive test cases for each release is beneficial when the project demands consistent execution. This approach not only saves testers’ time but also ensures faster execution with minimal risk of human error.
  • Data-Driven Testing: Automation is essential for tests requiring the same cases to be run with different data sets. Manual testing in such scenarios can lead to monotony and a higher chance of missed data sets. Data-driven automation testing frameworks significantly reduce the time and effort required for these tests.
  • Volume of Test Cases: The quantity of test cases in the test suite determines whether or not to automate testing. Manual testing works for smaller projects with fewer test cases, but for larger projects with numerous test cases, automation becomes necessary.
  • Regression or Smoke Testing:Automated testing is ideal for regression and smoke testing suites, which need to be run after each defect fix cycle and at the start of each test cycle to ensure no new defects have been introduced and core functionalities work properly.
  • Order of Executing Test Cases:In projects where the order of test case execution is critical, automation is advantageous. Manual execution requires QA team members to remember the order for each iteration, adding complexity, time, and potential for errors. Automation allows for setting the sequence and priorities of test cases.
  • Cross-Platform Testing:Because manual execution is laborious and prone to error, automating tests across several environments or platforms is essential. Automation enables simultaneous execution of the same script across multiple systems, streamlining the process.
  • Scenario Testing :We must first define the term “scenario” in order to make things clear. A scenario in software development is a user’s path through a program or website. Finding out how users interact with the functionality and potential issues is the responsibility of a tester. A collection of manual or automated test scenarios used to identify the advantages and disadvantages of a project is called a test scenario. It gives a summary of the things that a QA business must test.

A test scenario’s primary goal is to evaluate the whole system’s performance from the perspective of the end user. It is necessary for a tester to imagine oneself as a user. They can clearly see what real-world scenarios the program will have thanks to it.

Scenario testing is a quality assurance method used to evaluate how a software application functions in real-world situations. This approach involves creating detailed and comprehensive scenarios that mimic actual use cases, allowing testers to explore how the software behaves under various conditions.

How QA Automation Functions

  • Set Goals: Specify short- and long-term objectives for test automation. Engage with senior management and stakeholders to outline a clear roadmap.
  • Test Approach Planning: Recognize various testing levels and avoid limiting automation to end-to-end testing. Construct test pyramids for a comprehensive testing approach.
  • Select a Framework: Choose an appropriate automation framework after understanding the business value. Discuss with the team to select the most suitable framework.
  • Test Automation Environment: Determine the environment where the application will be used (development, staging, production, or a combination). Implement an efficient test grid for parallel testing to run multiple tests on multiple devices simultaneously.
  • Risk Analysis: Conduct a thorough analysis of potential risks associated with automation testing and communicate these findings to management. Be aware of the risks related to the chosen tools and strategies.
  • Develop, Execute, and Maintain Tests: Start with creating automation tests for critical features. Run and maintain these test cases on a regular basis to adjust to ongoing development changes.
  • DevOps Integration: Integrate with DevOps to reduce the testing team’s dependency, allowing any team member to run tests and access reports.
  • Reporting: Provide thorough reports that list all test cases that have been run as well as the number of cases that have passed and failed. Make sure stakeholders who aren’t technical can grasp the reporting.
  • Review and Retrospect: Continuously review test scripts to identify causes of false failures and improve the process, aligning with the initial goals and automation strategy.

Stages of QA in Web Development

  • Requirement testing: To ensure clarity and compliance with project standards, QA engineers carefully examine both functional and non-functional needs for the website.
  • Testing Plan and Checklist: QA engineers create a detailed plan based on their analysis, which includes the strategy, scope, budget, timelines, resources, testing methods, necessary software, and procedures for reporting issues.
  • Design Testing: Test scenarios and the testing environment framework are devised to maximize test coverage with minimal resources.
  • Functionality Testing: Specialists check whether the program functions as intended, ensuring the final product is high-quality and aligns with market demands and user expectations.
  • Regression Testing: Quality assurance teams evaluate existing features with each new code update to ensure that the changes do not negatively impact the current functionalities.

Quality Assurance Checklist for Web Development

  • Validation Testing: Ensuring your website meets a client’s requirements is crucial. Tools include XML Validator, Mechanical Auditors, Site Evaluation Tool, and CSS Style Sheets Verifier.
  • Browser Compatibility Testing: Thorough cross-browser testing is essential to confirm that the display is accurate across popular browsers such as Edge, Opera, Chrome, and Brave.
  • Device Compatibility Testing: Verify that the website functions correctly on a range of devices with different operating systems.
  • Input Testing: Essential fields on the website must work correctly, covering different scenarios including mandatory and optional fields, alphanumeric entries, and date fields.
  • Bug Testing: Perform multiple rounds of QA testing for complex websites, evaluating the storage of user-provided data, website functionality after cookies are deleted, and conducting stress tests.

Advantages of QA Automation

  • Reduced Testing Time and Costs: Continuous application releases necessitate thorough testing to identify and fix defects. Manual testing can delay updates, whereas QA automation allows the same test scripts to run on various hardware and software configurations, enabling continuous testing. Automation testing is faster than manual testing, leading to reduced testing time and costs.
  • Enhanced Product Quality: QA automation broadens the testing scope, allowing numerous test cases to be executed simultaneously across multiple platforms and devices. Unlike manual testing, automation can thoroughly inspect applications, examining memory data, data tables, and internal file structures, thereby improving product quality and performance. Automated regression testing ensures all application features are tested, which is difficult to achieve manually.
  • Optimized Resource Utilization: Automation testing allows QA team members to focus on more advanced product testing activities. By automating functional and regression test cases, the need for a large QA team is reduced, lowering expenses related to hiring and training software testers. Experienced QA resources can focus on developing superior test cases instead of performing routine tests.

Challenges in QA Automation

  • Dependency on Human Expertise: While automation tools simplify many tasks, they cannot replace the nuanced judgment and capabilities of skilled human testers. Effective QA automation depends on professionals with deep programming knowledge and proficiency with testing tools.
  • Tool Selection Complexity: The vast array of automated testing tools available makes choosing the right one challenging. Not all tools are compatible with every application or software architecture, adding complexity to the selection process.
  • High initial setup expenses are associated with implementing an automated test framework, which presents a number of issues. It takes a significant amount of money and knowledgeable staff with experience with testing instruments and programming languages to maintain these frameworks.

Best Practices for QA Automation

  • Assess Test Cases for Automation: Not all tests are suitable for automation, especially those needing human intervention. Focus on automating repetitive tasks and those involving various data sets. Prioritize crucial tests like Smoke and Sanity tests, which are performed regularly for each iteration or release.
  • Opt for the Right Automation Tool: Choose an automation tool based on the project’s platform and technology. Consider team members’ proficiency with programming languages such as Java, Python, JavaScript, or C#. Factor in the project’s budget to decide between open-source tools like Selenium or commercial ones like Cypress or Katalon.
  • Divide Work Based on Team Expertise: Allocate tasks according to team members’ skills. Some team members may excel in framework creation and utility structuring, while others are adept at writing test scripts. Proper assignment of responsibilities expedites automation testing efforts.
  • Develop Scalable Data-Driven Tests: Create comprehensive test data stored in various formats such as XML, Excel sheets, or JSON files. Using external data sources allows for reusable and maintainable automated tests, making it easy to add new data scenarios without modifying test scripts.
  • Test on Real Devices: Given the variety of devices in use today, it is crucial to test applications on the latest devices and browsers before deployment. While setting up an in-house device lab can be challenging, leveraging a cloud-based testing platform like LambdaTest’s real device cloud offers a practical solution. Using over 3000 environments and real mobile devices, LambdaTest is an AI-powered platform for test orchestration and execution that enables both real-time and automated testing.

Conclusion

Combining automated and manual testing maximizes the identification of bugs and defects. While automation streamlines many testing processes, some essential tasks still require human input. These include strategizing the automation process, selecting suitable automation tools, and developing, maintaining, and managing continuous integration and deployment. Software testing cannot completely replace manual testing, at least not to the same extent.
