Regression Testing is a process that enables you to check whether the recent changes you made in your application or software have led to serious altercations in the working or efficiency of your product. For some strange reason, not many people put enough attention to this testing, resulting in failure of the app at times. As regression testing involves a re-run of the same tests again, few enterprises count it as an extra expense and end up avoiding it. However, making sure that your product undergoes regression testing is one of the key factors that decide the fate of the growth for your business.
The major benefit of performing regression testing is that it provides you an opportunity to ensure that your application works just fine even after the updates you have made to it. With thousands of lines of coding, it is almost impossible to check the specific effect of the update on these codes. This is where Regression testing comes to rescue by re-running the tests again to ensure the functionality of the application.
What is the right time to perform Regression Testing?
The ideal time to use Regression Testing is before you release the application to the public. Integrating it right from the initial phase of the application and during the developmental phase makes sure that you app is just perfect to use. Following are the four instances where the use of regression testing is unavoidable.
• After a bug or an error has been fixed
• When there is a change to incorporate the requirements of users in general
• When there is a change the module of the system, you need to integrate it with the existing system and such cases demand a regression test
• When there is a modification done on your end to make the application better
Why do companies want to avoid Regression Testing?
Not using DevOps or Agile
Even with the inception of efficient testing methodologies like DevOps and Agile, some companies still use the Waterfall technique. This results in a wide gap between the testers and developers, hence resulting in a long process of testing. Such cases demand testing from scratch. This is where DevOps and Agile play a crucial role by bridging the gap between testers and developers. Each and every change made in the digital product will go through everyone and thus resulting in a more efficient testing phase, leading to test conducted only in the necessary areas.
To make it cost-effective
Since regression testing involves a re-run of a few tests, it is considered to be arduous and expensive and hence people stay away from it. Some see it as adding little value to the overall process and therefore do not find it necessary to allocate specific budget for it.
Test Case Selection
Since Regression testing is time bound, selecting the right test is crucial. Furthermore, there is no time to run large test runs. Therefore, the only option for the testers to choose the right and the most necessary test to run.
Updates in highly complex products
When highly complex products get updates, it is hard to keep track of the changes made in the test cases. More complex the update is more changes you have to make in your tests cases. In such cases, people often skip the part of regression testing.
How can you include Regression Testing in your testing?
Increase the frequency of tests
One easy way to incorporate Regression testing is to come up with small yet frequent tests. This will ensure that the test cases are always updated and no large tests have to be run. This allows the users to develop the tests cases and provide feedback simultaneously.
Automate what you can
Automation is the key to testing in today’s world, as there is no other way to get faster results. It is important to identify the tests that do not get affected by the updates or changes, so that you can forward those tests for automation testing. You just need to perform regression testing on necessary tests. This not only saves time but also helps you be well within the budget.
Review the changes made to your codes
Whenever there is a change in the codes of test cases, you should conduct a review meeting with all the coders and testers involved. This keeps them in the loop about the changes made, which helps them in the further coding.
Make a strategy to include Regression Testing efficiently
• Narrow down the tests cases involved in Regression Testing
• Analyse and scrutinize each of the test cases before performing it
• You need to identify the areas that are more prone to risk and failure
• Keep track of the existing test cases to erase it if it gets superseded
• Keep performing random tests under various real-life scenarios
Even if many of you feel that Regression Testing is not that important, smart enterprises invest smartly in regressive testing, making sure that their app delivers on all fronts. Accuracy, speed, efficiency and performance are the key factors that make an app attractive for the user and Regression Testing allows you to have the very same.
