3 Challenges of Regression Testing with Solutions

1. 3 Challenges of Regression Testing with Solutions

2. There are many phases to the software development cycle. One essential phase is testing. However, if you don't have the right testing processes in place, it can negatively impact your business. A software glitch caused more than 100 disruptions in flights between London's Heathrow airport and London's Heathrow airport on February 16, 2020. A tech report estimates that software failures have resulted in financial losses exceeding $1.7 trillion for many businesses from different industries. It is clear that software must have a reliable testing program in order to be successful on the market.

3. Regression testing pros and cons • Software testing is not without its challenges. Regression testing has been proven very effective in ensuring consistency between different versions of software.  • Pros • You ensure that any changes in the code do not impact the software's functionality • Software can resolve any recurring problems • Identifies and mitigates unforeseeable risks • You can lower maintenance costs by eliminating or reducing downtime • Cons • To avoid long processing times, automated testing cases are necessary • Re-testing may be required in large numbers • It is necessary to develop test cases according to the requirements

4. Regression Testing Challenges 1. Cost and time factors Regression testing requires business investment. The cost of repeating the same test over and again can be prohibitive. It is also tedious and time-consuming. Your resources are used for a particular period. This can impact your entire testing budget. Solution: Automation of regression testingis the best solution. Automation of repetitive test cases can save you valuable time and resources. This is where it is crucial to prioritize tests based on functional requirements. It will increase test cycle productivity. It will optimize the investment costs and use of resources. 2. The value problem Regression testing is a way to ensure that bugs are caught early. Many companies aren't convinced of the benefits this testing approach offers. These are some of the questions you may be asking yourself. Solution: Make sure to educate the testing and development teams about the importance of regression testing for early detection. You can share various scenarios of software failures with your team to highlight why early detection is a wise decision.

5. 3. Lack of clarity • Regression testing requires a clear definition and measurement of goals and metrics. Incorrectly defined, it can lead increase in costs. The main challenge is to create a detailed document that includes pre-defined metrics. • Solution: • Before creating a comprehensive document on different regression testing metrics you need to be able to assess the potential impact of each one. These are some of the things you should keep in mind. • The code percentage can be used to determine how often code is changed and their effect on the software. • Cyclomatic complexity can be used to assess the multifaceted nature and functionality of software, especially when testing white boxes. It is useful in assessing highly risky bugs. • This percentage shows the average number of passes during the testing process.

6. Conclusion Regression testing isn't the only type you might need to do. Regression testing does not have to take priority. What resources do it need? This can pose a problem for the testing team. These challenges can be overcome by using the right regression testing strategy.
