Impact Of AI In Regression Testing: Power Of Automation in Software QA
AI in Regression Testing: Revolutionizing Software Quality Assurance
In the fast-paced world of software development, ensuring the reliability and functionality of applications is paramount. Regression testing, a critical component of the software testing lifecycle, ensures that new code changes do not adversely affect existing functionalities. Traditionally, this process has been manual, time-consuming, and prone to human error. However, the integration of AI in regression testing is transforming this landscape, offering enhanced efficiency, accuracy, and scalability.
It is estimated that over 60% of the test cases are redundant and prone to errors and a lot of it can be blamed on human errors that creep in while designing the test case scenarios. Manual testing also introduces risks associated with human errors and this challenge is even more prominent when applications are being developed and deployed across multiple platforms and devices. For example – creating comprehensive plans for identifying corner cases is difficult, and then finding them in manual testing becomes a hit-and-miss game.
A key requirement for addressing these issues has always been the need for dev & test teams to find better approaches for designing test cases as well as methods for manual testing.
So it’s a no-brainer that Artificial Intelligence (AI) could be the missing link to achieving even higher agility and rigor that ultimately delivers better software. AI in software testing helps you maximize defect detection and risk coverage while reducing costs, execution time, and the number of test cases.
But why exactly does test automation fail?
Test automation tools are considered to be the gold standard for software testing, and are a critical component of testing. However, there are some well-known hurdles with automation. These include, but are not limited to:
1. Deciding Which Tests to Automate:
It is one of the biggest challenges of automation testing. Many businesses and software testing teams fail to correctly identify automation tests, and conversely which ones should be tested manually. Here are some factors you need to consider while automating test cases.
- High-value and business-critical tests
- High-volume, repeatable, and tedious tests
- Stress and load tests
- Frequently used functionalities
If you are conducting tests on a stable entity that necessitates repetitive and continuous actions, automation testing is recommended. However, if you are dealing with a dynamic system that undergoes frequent changes, relying solely on automation may not be advisable.
2. Selecting The Right Tools:
Among many tools, selecting the right tool is always a challenge for QA teams. It’s not merely about choosing the most trending tool in the market. It’s to evaluate a tool’s features and functionalities before investing.
There are some factors to check before selecting a tool.
- How can we reduce the time and effort required to implement and maintain test scripts and suites?
- How can I create useful test reports and metrics?
- Check how automation test suites be designed and implemented correctly to keep up-to-date quickly with minimal maintenance effort.
3. High Maintenance of Traditional Script-based Tests:
With traditional automation, testers need to spend considerable time learning how to script each test scenario. Script-based tests need to be maintained and updated frequently whenever there is a new feature or product improvement introduced.
On the other hand, scripts become as vulnerable to defects as code is. This means that when we have defects in our test scripts, it causes false positives and script errors that create burdens for the QA teams.
4. Over-Emphasis on UI Testing:
Traditional test automation approaches focus more on UI testing, which involves interacting with the application’s Graphical User Interface. While UI testing is essential, it is often fragile and time-consuming. This overemphasis on UI testing can lead to the neglect of other crucial layers of testing, such as API or unit testing. By overlooking these layers, traditional test automation fails and may compromise the overall effectiveness and efficiency of the testing process.
The Evolution of Regression Testing
Regression testing involves re-executing previously conducted tests to confirm that recent code changes have not introduced new defects. As software applications grow in complexity and scale, the volume of test cases increases, making manual regression testing increasingly challenging. AI addresses these challenges by automating various aspects of the testing process, thereby accelerating test execution and reducing the likelihood of errors.
Role of AI in Software QA Testing and its Benefits:
1. Regression testing automation:
Regression testing is tedious, time, and resource-intensive process. Whenever there is a change in the code, the QA team has to check the application’s functionalities and confirm that the pre-existing features are still working as required. Though regular automation helps QA teams, it further lags in learning from test results and early detection of bugs with higher potential risks.
AI-powered regression testing is an intelligent way to automatically generate test cases, identify relevant test scenarios, and prioritise tests based on their severity. Together with ML, AI can continuously learn from test results and adapt test suites to focus on areas with a higher potential for risk. This results in faster test execution, enhanced test coverage, and early detection of software regressions. This further reduces manual effort and time while ensuring higher-quality software releases.
2. Defect Prediction:
In conventional testing methods, a few bugs and errors remain unnoticed for a long time and create roadblocks in the future.
Defect analysis is a continuous process of quality improvement and planning. One of the best applications of AI in software testing is its ability to predict defects before they occur and become vulnerable. AI in software testing uses historical testing results to predict defect metrics for future releases. This enables your QA manager to take corrective actions to ensure your project meets the necessary KPIs.
