Regression testing does not get the prerequisite attention from the top tier management. The re-performing of the tests on the already tested features is counted as paranoia by the management. Regression testing plays a vital role in ensuring that the software does not blow up on your face.
The need for regression testing
The sheer size and complexities of the codes which are written for the software makes it challenging to determine the effect of a minor bug fixes or update. This is where the regression testing services comes into being.
With the analysis of core performance and functionality, you can be ensured that the updates are not throwing the software away. In addition to this, it also plays a vital role in ensuring that the interdependencies in the specific code are working seamlessly.
Tips to perform regression testing
For maintaining the striking balance between frequent testing and faster development, it is essential to integrate regression testing at the very starting. It plays a vital role in the release process and thus it is considered to be equally crucial like the development stage.
Regression testing is done to fix an error or bug. It is also done for introducing a new functionality of feature. In addition to this, it is performed when the existing system is integrated with a new component or module.
In addition to the reluctance of the business organization for adopting regression testing, there are different challenges, encountered by the business organization. In spite of the wide-acceptance and popularity of DevOps and Agile methodologies, there are a wide array of business companies which follow the Waterfall structure.
Waterfall boasts of a siloed structure owing to which it becomes impossible for the testers to be aware of any changes, which are made by the software developers.
Owing to this, it is a must for them to conduct regression test suits which can consume a lot of time and might break rime. In DevOps and Agile, testing is considered to be the responsibility of the whole team.
Once the barrier between the software testers and developers is removed, every member of the team can be informed about even the slightest of the changes. This reduces the requirement for running the whole test suite. It is possible to do the regression testing in the specific areas in which changes are introduced.
Tips to support regression testing
It is essential to opt for smart work for overcoming the specific challenges. Here are some tips which will be useful for supporting regression testing:
Frequent and small releases
It is really easy to perform regression testing on the smaller codes, in comparison to the full releases. The developers should be motivated for keeping the deploying sections of the latest release to the test environment and thus it will be possible for testing and providing feedback simultaneously.
For regression testing, cognitive intelligence is required for identifying the test cases that need to be performed, the areas for analysis after a specific update. You can consider using automation for obliterating the redundant part of the technique.
It indicates that regression testing can be automated for the specific components which are unaffected by the specific update. As you do so, you will gain success in saving a significant amount of time.
Thus, testers will be capable of focusing on the specific areas which require undivided and focused attention. As you depend on automation, you will be capable of removing any negative effect on the quality of the final product, thereby reaping the benefits of regression testing.
It is a prerequisite for the testers to participate in the code review meetings actively. It does not really matter whether they have any updated knowledge of coding. As they take participation in the code review meetings, they will be capable of getting updates about the changes, which are made to the code. This helps them in focusing their attention to those specific changes during regression testing.
Effective strategies for regression testing
It is essential to devise effective regression testing strategies, adopt careful efforts and planning along with active involvement of the whole team. Here are some steps that help in creating regression testing strategies successfully:
Collection of the expected test cases as well as monitoring the changes closely is considered to be one the crucial steps for the creation of regression testing strategy successfully. You also require scrutinizing the changes and analyzing the effect on various components.
In addition to this, you require developing new test cases as well as modifying the already existing test cases, accordingly. Besides this, it is recommended to determine the specific areas which are more prone to failures and risks.
Besides this, you require giving a priority to the test cases. Do not forget to estimate the specific time for the execution. In addition to this, you require identifying the test cases which can be automated or put into motion.
You need to polish the test case occasionally which can be done by removing the obsolete test cases and the addition of the latest ones. Besides this, you require performing random testing under a plethora of user scenarios.
You need to provide deliberate consideration about which automation tools need to be used. It is necessary to design the test environment carefully for mimicking the real scenarios in the best possible manner, thereby offering the most amazing test results.
A software or app should be capable of delivering value to the customers which can be accomplished in terms of performance, accuracy, efficiency and speed. With the regression testing, it is possible to ensure that the app is delivering on these parameters and providing the ultimate level of satisfaction to the targeted audience.
Hence, without a second thought, it is recommended to initiate regression testing at the starting of software development process. It plays a vital role in ensuring the least disruption and keeping the costs under the control.
Changes might be introduced in the test environment in the form of alterations in the database updates, deployment configurations, and operating system updates. Changes might also occur in the app in the form of new functionality, bug and error fixes, integrations, functionality enhancements, interfaces, patches, etc.
