Why Do We Automate Regression Testing?
Everything that can be automated should be automated, as I frequently remark. In other words, if you have the ability to automate a process, you should. I'm afraid you're wasting money if you can automate a procedure but still perform it manually. Manual processes are likely to be slow, time-consuming, boring, and prone to errors. That means you're squandering cash in at least three ways.
For starters, having well-paid professionals execute jobs that could be automated is a waste of money. Then there's the cost of missed opportunities. The test takers may be doing something more useful.
How to Use Automated Regression Testing in Project
Now that we've covered the fundamentals of regression testing, let's look at some practical advice on how to put it into practise.
There is some positive news to report. If you develop automated tests for your application, such as unit tests, you're already performing
regression testing without even realising it.
Regression testing isn't a "new" automated test category. It's not a replacement for unit or integration tests. Your automated tests—unit tests,
integration tests, and other similar tests—written from the beginning of the project can and should serve as regression tests. Simply re-run after
each new update to the codebase.
Best Practices for Automated Regression Testing
In addition, regardless of the specifics of your implementation, there are several common practises you should follow when doing regression testing:
- Adopt a Test Management Software: This is essential for any project greater than a one-developer toy. You'll have a lot more test cases than you'll be able to track and handle on your own. Fortunately, you have a variety of test management solutions at your disposal.
- Maintain a Testing Routine: Throughout the project, you should stick to a rigid testing schedule. As a result, the finished project will be thoroughly tested. Furthermore, the schedule will motivate the crew to work hard
- For each new bug discovered, create a new failing test: Assume your code contains a clear and repeatable bug. Your tests, on the other hand,
are all passing. That either means your present tests are incorrect or your test suite is missing tests. Write a new failing test to document the bug if
you find yourself in this situation.
- Split Your Test Suite Into Smaller Groups: You should divide your test suite into smaller categories. Your test management tool will almost certainly allow you to categorise your tests. Your team members will be able to simply recognise each type of test this way.
