What is Regression Testing & Why Should it Be Automated?

Regression testing is considered to be an important aspect of software testing as it makes sure that the changes that have been introduced in the code do not alter or modify the existing functionalities. Existing test suites are being re-run to make sure that the existing functionalities are working as expected. When the platform of regression testing is automated, the performance of regression test activities is leveraged. In this article, you will get to know about regression testing and why it should be automated.

What is regression testing?

It is a testing method wherein an already released software is assessed to make sure that no new functionality has been affected as a result of modifications or changes being made to the software. The platform of regression testing makes sure that the functionality of current features and overall stability are properly maintained.

The right context to perform regression testing:

1. A software update takes place: For regular software updates, continuous regression testing is carried out. This in turn ensures that the newer update does not impact the previous functionalities.

2. Carrying out integration: When third-party applications require new integrations, then code changes may happen, which may in turn disrupt previous functionalities.

3. When the existing application goes through certain changes: Modifications or even small tweaks may cause havoc on the overall functionality. Changes such as minor workflow adjustments or adding a new field can trigger the need to run regression tests.

4. A new functionality or feature is being added: Customizations, pre-existing integrations and the current application can be negatively affected by introducing new functionalities or features.

5. Analyzing performance issues: Even if modifications to the system have not been made, executing a regression test is considered to be a strategic move. When performance issues are being experienced, those problem areas should be pinpointed that are causing performance issues.

The following are the key factors that depict the necessity to automate regression testing:

1. Repetitive tasks are reduced or eliminated: Menial, repetitive tasks are eliminated through the platform of automated regression testing. Whenever new features are being added, regression test suites expand. The full regression test suite will be quite challenging to run within a short timeframe.

The full suite of regression tests is run by teams through the automation platform in a shorter timeframe and thus the monotonous, boring work is freed up for users.

2. The performance factor: The application's performance and stability are improved by automated regression tests. With each update, an ERP application can become more complex. Using manual regression testing would not be considered to be a tactical move. Hence, the possibility of human errors is reduced by the automation platform, which, in turn, results in a stable application.

3. Enhanced scalability: Once the development of automated regression tests has been done, it can be used continually in the future, through which the need to re-create them multiple times is eliminated. Automated regression tests test cases can be run for any length of time, as it has no specific time constraints.

4. Improved coverage: Greater coverage is provided by automated regression testing. When manual regression testing is carried out, it would be quite challenging to know when to test, what to test and how often to test. The power of AI is leveraged by intelligent test automation platforms so that a deep dive into the business processes can be performed. The specific business processes that need the most testing can be identified, which, in turn, helps in achieving optimal coverage quickly.

Conclusion: If you are looking forward to implementing regression testing for your specific project, then do get connected with a top-notch software testing services company that will provide you with effective testing solutions and strategic advice that is in line with your project specific requirements.
