Unit Testing Vs Regression Testing: A Comprehensive Guide

Ever deployed code only to watch everything crash? We’ve all experienced that sinking feeling ,which is exactly why testing matters so much. While most developers understand that testing is vital, two important approaches : unit testing and regression testing are frequently confused, despite serving completely different functions. In this blog, we’ll clear up the confusion, examine their core methodologies, and how tools like Keploy can automate and enhance your testing processes.

How To Build A Regression Test Plan?

Regression testing is notoriously repetitive and time-consuming. As your software grows in complexity, manually testing every existing features is just counter-productive. This is why regression testing is an ideal potential for automation. One of Katalon's customers, Liberty Latin America, upon adopting regression test automation, has seen 50% decrease in testing time, which ultimately translates into rippling benefits across the entire QA process.

How To Do API Regression Testing?

API is the backbone of many software architecture. However, it is also one of the major points of technical conflict. When a major code update happens, it is really important to check on these APIs to ensure that those code modifications did not inadvertently break existing functionality. This is why API regression testing should be considered in your regression test planning.

Playwright Regression Testing Test Plan: Best Practices & Tools

In the dynamic world of software development, ensuring that applications remain stable and functional as they evolve is crucial. This is where regression testing plays a vital role, especially when employing powerful test automation tools like Playwright. For software developers and QA professionals, creating a detailed test plan for regression testing using Playwright can significantly enhance the efficiency and reliability of testing processes.

Top 5 regression testing services & key factors to consider

Outsourcing is an affordable way to scale regression testing, freeing up developers to focus on shipping code. However, we’ve surveyed engineering leaders and developers and found that outsourcing regression testing to the wrong service provider can lead to several issues: As a result, we recommend evaluating how a regression testing service provider addresses these three issues before partnering with them.

Regression Testing Best Practices: Risk Management Guide 2025

Picture this: You’ve just deployed a new feature at work, and you’re buzzing with excitement. But suddenly, you hear whispers of a critical bug in the old functionality. That gut-wrenching moment reminds us how important it is to address regression testing. In this post, we’ll delve into the legacy views of regression testing, explore its modern implications, and highlight why risk management is the real MVP in ensuring robust software development.

How to Automate Regression Tests While Handling New Features?

With resource constraints, QA team usually has to juggle between regression testing and new feature testing. ""Don't think about regression test automation as something separate,"" said Alex Martins. He believes that it should be a combination of both. Check out Alex's way of maintaining that testing equilibrium below. Don't forget to follow Katalon for more insights in our series!
