Regression testing is a vital component of guaranteeing the quality of software, particularly in cloud-based environments where continuous updates and changes are the norm. Regression testing aims to verify that previously functioning features and functionalities of the software are still operating as expected after changes or updates have been made. Through running a series of automated and manual tests, regression testing can swiftly identify any unintended impacts on the software caused by new changes or updates.
By understanding the purpose and importance of regression testing, software development teams can guarantee that their products remain stable, steadfast, and meet the expectations of end-users. Henceforth, it is paramount to integrate regression testing into the software development cycle and to guarantee that the process is invariably applied throughout the development process.
Developers and testers perform software regression testing every time the code is changed. The scenarios for executing regression testing are:
- There exists a recent development with added functionalities.
- Modifications are made to the existing specifications.
- If there are any errors or flaws, then that is rectified.
- Performance issues are fixed.
Here are some best practices to ensure software quality of regression testing in the cloud.
Choose the Right Test Cases
Regression testing is a fundamental aspect of guaranteeing software quality, especially in cloud-based environments where applications are delivered via the Internet. To accomplish adequate regression testing, it is vital to choose the suited test cases that will ensure maximum test coverage and accuracy. The first step in determining test cases is to specify critical functionalities of the software that have altered since the last release. These functionalities must be tested comprehensively to make sure they are working as expected.
Additionally, it is paramount to select test cases that cover different scenarios and edge cases to guarantee the software can handle unanticipated occurrences. Furthermore, selecting the suited test cases can assist in reducing the cost and time associated with testing, as well as increase the likelihood of catching defects before they reach production. Henceforth, selecting the suited test cases is a critical best practice for successful regression testing in the cloud.
Understand the AUT/Product Adequately
The Quality Assurance teams need to deeply understand the application to comprehend the areas that would be more prone to flaws due to the new changes. One way to enhance your understanding is by creating story cards for each module and linking them together to illustrate the interconnections between the modules more cohesively. By utilizing this approach, it becomes straightforward to determine the inter-module dependencies and the potential impact of any changes made to a particular module on other interconnected modules.
Develop a Comprehensive Test Suite
Developing a comprehensive test suite is a crucial step in regression testing, guaranteeing that your software functions as intended after implementing changes. A comprehensive test suite should incorporate automated and manual tests, encircling a wide range of scenarios and edge cases. It is paramount to pinpoint and prioritize the most crucial functionalities and test them rigorously to uncover any defects or issues. Furthermore, it is imperative to guarantee that the test suite is invariably maintained and updated to stay abreast of any modifications made to the software.
Dev-Quality Assurance Pairing
Quality assurance can liaise with developers and testers during the programming of new modules. Again, this functions as an excellent medium for QA teams to document their observations and strategize their regression test suites to get the maximum test coverage for the release. Dev-Quality Assurance Pairing is an increasingly prevalent approach for teams to maintain a high level of quality in their software development. This collaborative approach allows developers and quality assurance professionals to work together and identify potential issues and areas for improvement while programming new modules.
Prioritize Test Cases based on Risk
Prioritizing test cases based on risk is a best practice that should not be overlooked when it comes to regression testing in the cloud. It helps to guarantee that the most integral parts of the software are tested comprehensively before release. This implicates pinpointing the areas of the software that are most likely to have defects or that would have the most significant impact if defects were present. By prioritizing these areas, teams can concentrate their regression testing efforts where they matter most. This method helps to diminish the possibility of critical defects slipping through the cracks and being released into production.
Identify the Regression Test Coverage Right
Here are a few points to consider for marking a test case as a regression test prospect:
- The test cases cover the fundamental workflow of typical organization use cases.
- Areas with a high risk of AUT cases.
- The test cases that enfold the core components of the AUT.
- The primary and crucial test case for an e-commerce web application is the seamless integration of the application with the payment gateway. That is why it should be present in the regression pack.
- It can be beneficial to retain test cases that have exposed defects in previous testing cycles.
- Develop a logical set of test cases rather than maintaining exhaustive one-to-one test cases.
- Maintain consistent monitoring of the regression test suite and ensure its frequent updates as the application development progresses.
Automating Regression Suites
Grooming the regression suite is a continuous and iterative process that begins at application startup and is maintained throughout the product’s lifecycle. It is recommended that this suite comprises a significant number of test cases to ensure comprehensive test coverage. In some instances, thousands of test cases may be necessary to achieve this objective. Manually conducting this task creates a significant burden on the testing teams.
To prevent such occurrences, it is advisable to implement an automation tool framework that can execute regression test suites and promptly notify development teams of any code modifications that cause application malfunctions. This drastically diminishes the testing steps and gets the issues pinpointed and fixed swiftly.
To automate the regression suite, choosing a cloud-based platform like LambdaTest leverages the true capability of the test process.
