In the fast-paced world, businesses need to change or upgrade the existing functionality of their software to fulfill the end-user requirements. However, changes in code to add new functionality or features can severely impact the existing functionality. That’s where regression testing comes into the picture.

This is a critical step in which businesses must go back to the existing code to ensure the functionality remains as intended after making changes. However, regression testing can be performed manually or using regression testing tools like Opkey.

This blog will guide you through the need for regression testing, testing methods you should adopt, and top regression testing tools.

Exploring Regression Testing

Regression testing is a critical step in the software development cycle, which ensures change, addition, or upgradation in code doesn’t negatively impact the existing functionality. This helps you identify errors or unexpected behavior after introducing the new features. Simply, regression testing ensures your software’s quality, reliability, and integrity.

What Is the Need for Regression Testing?

Identifying Unintended Side Effects

Changes made in one part of the code can severely impact the other parts of the code base. Regression testing allows developers to identify the defects and prevent unintended side effects. However, developers can use regression testing tools to identify the bugs, ensuring the quality of the software.

For example, CRM applications keep releasing updates to improve the functionality of their software security and fix bugs. After upgrading, businesses might face compatibility issues, UI changes, or performance issues. Developers return to the new code and perform regression testing to find the bugs.

Evaluate Change in Code

Developers should ensure the seamless implementation of new code with the existing one to ensure the software’s stability. With time, the requirement of the end user evolves, so developers add new features, fix bugs, and multiple code changes.

With regression testing tools, QA teams can identify and rectify the bugs, ensuring software remains stable.

Maintaining the Existing Functionality

After every code change, ensuring that existing functionality isn’t interrupted is essential. Developers perform regression testing to ensure new features don’t distort the existing functionality.

Automation vs Manual: Which Is Better?

Regression testing can be performed manually or automatically with the help of regression testing tools. In manual testing, analysts and QA engineers are involved in test creation and execution manually. On the other hand, automation testing is the process of performing tests using tools and scripts.

Manual regression testing is repetitive. There are higher chances of human errors. Automation testing automates repetitive tasks, reducing the risk of human errors. Moreover, tools can execute the testing faster than testers, saving time and resources. Automation testing is suitable for complex scenarios where you need to perform testing on a large scale.

The collaboration of manual testing and automation can provide better results. Manual testing takes care of complex test cases, and automation testing takes care of simple and repetitive tasks.
