I’ve been trying to understand retesting in software testing and how it’s used in real-world projects. From what I’ve learned, retesting is done to verify that a specific bug has been fixed by running the same test cases that previously failed.
It’s a very targeted approach—unlike broader testing methods, retesting focuses only on the exact issue that was identified earlier. This makes it useful for confirming whether a fix actually works without testing the entire system again.
In modern development workflows, especially with APIs and microservices, retesting becomes important because even small fixes need to be validated quickly before moving forward.
I’ve also seen teams using tools like
Keploy
to simplify this process by capturing real API interactions and turning them into reusable test cases, which helps in verifying fixes faster.
For a detailed explanation, I found this useful:

How do you handle retesting in your workflow—do you keep it manual or automate it?
