This includes all the modules and components of the software application that may be affected by the changes. These modules and components should be tested to ensure they work together seamlessly.
- Performance
This step includes the software system’s performance before and after the changes. The performance should be analyzed, ensuring the changes do not negatively impact it.
Checklist to Follow During Regression Testing
As you know, regression testing is an essential step in the software development process that ensures changes introduced in the software application do not cause any unintentional effects on the existing functionality. In the process of re-executing the test cases that were previously executed to check if the newly implemented features have not adversely affected the application’s working, the testing team checks the ensure that the software behaves consistently and accurately under various test conditions. It provides efficient and accurate regression testing, and a well-planned checklist is necessary. There are some essential steps to consider when creating a regression testing checklist:
- Define the scope of regression testing.
Before proceeding with regression testing, the first step is essential to determine the scope for testing. Areas of the software will be tested and at what levels. You need to the entire software application or components/sections that will undergo regression testing and ensure nothing.
- Determine the test environment.
It is important to consider the test environment when carrying out regression testing The ensure that the testing environment mimics the production environment where the software will be deployed. It will ensure accurate and high-quality software delivery.
- Identify Test Cases to be re-executed
Choose the right sets of test cases that will be re-executed for regression testing. Select functional test cases, integration test cases, and security test cases. This includes both positive and negative cases.
- Prioritize Test Cases
When conducting regression testing, the first step is to assign priority to test cases based on the criticality of features and potential impact on software application functionality. By prioritizing test cases in this manner, the testing team can ensure that the areas of the highest importance receive the appropriate testing attention. The approach can improve efficiency, ultimately leading to higher-quality software products.
- Validate new changes
The first step is re-executed, and you need to prioritize this. It is important to identify areas in the code that have been changed and need to update the corresponding test cases accordingly.
- Analyze the security
When you test the software application, it is important to ensure its security. It will help you analyze that the application is not vulnerable to attacks or exploitation.
- Ensure Automation testing
Regression testing often poses a significant time investment, which has led to the emergence of automated solutions to make this challenge. The implementation of automated regression testing not only ensures expedited turn-around times but also facilitates efficient testing practices. It is particularly recommended for systems that experience frequent modifications or updates, as it can significantly improve overall testing efficacy.
