What is Smart Regression Testing

  • April 7, 2023

Regression testing is a crucial aspect of software testing that ensures that changes made to the software do not adversely impact the existing functionality. With the increasing complexity and agile development of applications, traditional manual regression testing is no longer a viable option. Hence, automated regression testing has become the norm in the software industry. However, with the advent of smart regression testing, software testing has reached a new level of efficiency, effectiveness, and cost-effectiveness.

Smart regression testing, also known as intelligent regression testing, that utilizes machine learning algorithms and artificial intelligence techniques to optimize and improve the testing process. It involves using predictive analytics to determine which test cases are most likely to fail and prioritizes them accordingly, thereby reducing testing time and effort.

Smart regression testing is becoming increasingly important as software development becomes more complex. With the rise of agile development methodologies and continuous delivery practices, developers must be able to test their software quickly and effectively. Smart regression testing facilitates developers to accomplish this by ensuring that their software is thoroughly tested with no compromise either on speed or quality.

What is Smart Regression Testing?

Smart Regression Testing is an advanced form of automated testing. It uses intelligent ML algorithms to choose and prioritize test cases. This is based on the probability of finding defects. It is a technique that uses artificial intelligence (AI) to identify which test cases are most likely to uncover new bugs in an updated software application. The goal of smart regression testing is to minimize the number of test cases that need to run while still providing adequate code coverage.

Smart regression testing analyses the codebase and identifies the most critical areas to test. This analysis is done using machine learning algorithms trained on historical data from previous software releases. The algorithms use this data to identify patterns and trends in the codebase, allowing them to predict which areas will most likely be affected by changes. Once the critical areas have been identified, smart regression testing uses automated testing tools to test those areas. These tools can include unit tests, integration tests, functional tests, acceptance tests, accessibility tests, database tests, compatibility testing, usability tests, system tests, smoke tests, and sanity tests.

Implementing Smart Regression Testing

Implementing smart regression testing requires a structured approach. The following steps can be followed to implement smart regression testing:

  • Identify the critical test cases: Identify the test cases critical to the software application’s functionality.
  • Collect historical data: Collect historical data on past test results and code changes.
  • Train machine learning models: Use the historical data to train machine learning models to predict which test cases are most likely to fail after a code change.
  • Prioritize test cases: Prioritize the test cases based on their criticality and the predictions made by the machine learning models.
  • Execute test cases: Execute the prioritized test cases, starting with the most critical ones.
  • Analyze results: Analyze the results of the test cases and use them to refine the machine learning models.
  • Repeat: Repeat the process for each code change made to the software application.

Types of Smart Regression Testing

Smart Regression Testing can be divided into two categories: static and dynamic. Let’s discuss both types and their importance in the testing process.

Static Regression Testing:

Static regression testing is not an actual testing process but rather a review process. Static regression testing involves reviewing software artifacts, such as code, documentation, and requirements, to ensure that they have not been adversely affected by changes made to the software.

Test cases are not executed in static regression testing, and only manual or automated reviews are conducted. This review process is used to identify potential issues, such as coding errors, syntax errors, and logic errors, that could affect the software’s functionality. Static regression testing aims to detect defects early in the software development lifecycle before they become more costly and time-consuming to resolve.

It’s important to note that while static regression testing is not a testing process in the traditional sense, it is still an important part of the overall software testing process. Static regression testing can help improve the software’s quality and reduce the cost and time required for testing and debugging by identifying potential issues early in the software development lifecycle.

Dynamic Regression Testing:

Dynamic regression testing, on the other hand, is dependent on the feedback received from the test results. It is conducted after a change is made to the application to ensure that the existing functionality is not impacted. It involves comparing the results of the new tests with those of the previous tests to identify any discrepancies.

Dynamic regression testing is not conducted at the beginning of the testing process because it requires feedback from the previous test results. It is conducted when changes are made to the application or after a certain period, such as every two weeks, to ensure the application still functions correctly.

The need for dynamic regression testing arises because there may be defects that were not identified during the static regression testing, or new defects may have been introduced due to the changes made to the application. Dynamic regression testing helps identify these defects early on, so they can be fixed before they become a significant problem.

Finally, both static and dynamic regression testing are essential in the testing process. It is important to use both types of regression testing to ensure that the application is working correctly and free of defects.

Benefits of Smart Regression Testing

Smart regression testing has emerged as an innovative solution using artificial intelligence and machine learning algorithms to optimize the testing process, delivering significant benefits to software development teams. The benefits are:

Improved Quality:

One of the most significant benefits of smart regression testing is improved quality. Smart regression testing can prioritize critical test cases, ensuring that in light of applied changes the most relevant areas of the software are thoroughly tested. This mechanism helps in identifying defects more accurately and efficiently, thereby reducing the risk of missed defects during testing. This results in higher-quality software that is more reliable and robust.

Reduced Cost:

Smart regression testing can significantly reduce the cost of testing. By optimizing the testing mechanism through AI-led selection, smart regression identifies only the most critical areas of the codebase that need to be tested in light of recent changes. Thereby reducing the number of test cases that need to be executed, hence, saving on cycle time.

Shorter Time to Market:

Smart regression testing integrates seamlessly with continuous testing processes, which means that regression tests are run automatically and continuously as part of the software development process. This approach helps to catch defects early in the development process, which reduces the cost of fixing defects and shortens the time to market.

More Effective Testing:

Smart regression testing is more effective than traditional regression testing methods. By using artificial intelligence and machine learning algorithms, smart regression testing can identify defects more accurately and efficiently. It can also adapt to changes in the codebase, ensuring that the testing process remains effective even as the software evolves. This results in more thorough testing and more reliable software.
