Automated regression testing: All you need to know

Automated Testing: Let’s Make a Definition

Before we get into the “how” behind automated regression testing, let’s clarify what it is. What is automated regression testing and why should it be used?

What does “Regression” mean in “Automated-Regression Testing”?

To understand automated regression testing, the first step is to eliminate the “automated” portion. We must first understand what “X” is. Then, “Automated X” will be obvious. It may be even easier to grasp.

Why do we need regression testing?

Regression is an unintentional return to a past state, as we have just explained in the previous section. But, there is something more important that was not stated in the definition. Software regression means that the application returned to a poor previous state.

Regression Testing is Vital in Software

Software development is notoriously susceptible to regression issues. Every change or addition made by a developer can cause problems (or omissions) in areas that are not related to the original spot. A non-trivial project that is maintained by more than five people has a high chance of causing regressions in each release.

Regression Testing: Why Automate it?

Automating everything is a good idea. Automating a process is a good idea. If you are unable to automate a process, but still do it manually , then you might be wasting money . The manual process can be slow, tedious, time-consuming and error-prone. This means you are losing money at least three ways.

Automated regression testing: How to put it into practice

We’re now ready to discuss practical ways to implement regression testing. Good news! You can write automated tests for your applications, such as unit tests. Unit tests are a form of regression testing.

Best Practices in Automated Regression Testing

Regression testing is not your specific implementation. There are best practices that you can follow.

  • Maintain a Testing Schedule This will ensure that the final product is tested thoroughly. The schedule will also encourage team members to adjust to a regular testing program.
  • Create a new failing test for every bug found: Visualize your code as having an unambiguous, reproducible problem. All of your tests pass. This means either your current tests are incorrect or your test suite lacks tests. To document the bug, create a new failing test if you find yourself in such a situation.
  • Split Your Test Suite into Smaller Categories: Most likely, your test management tool will allow you to categorize all of your tests. This will allow your team to easily identify each type of test.

Automated regression testing: Get it to work for your team ASAP

Software development is an artistic endeavor unlike any other. However, there are many risks along the way to reap its rewards. Writing code can be dangerous because you may break existing functionality and add new features. Even when we fix bugs, older functionality can be brought back to life. Every small, seemingly insignificant change can lead to a terrifying regression.
