Why Performance Testing Is The Key To A Continuously Deliverable Pipeline?

The DevOps approach of a software development model integrates various methods that fasten and simplifies the build process for the developers. It consists of various testing methodologies like unit testing, integration testing, and functional testing. Testing is done to check the performance of the software. Software tends to behave differently in different scenarios. It depends on the number of factors like total users surfing the application, browser and operating system being used and many others. There may be circumstances where when 10 users were using the application it performed perfectly but as soon 10 became 50 it became haywire. Thus, it is important to determine that how the application will perform when it hits a high load.

Performance testing:

Performance testing in a software development cycle is the capability of an application or software to perform under a specific load. When performance testing or better say load testing is done at early stages of development one can eliminate a lot of performance related issues at a later date. Even if the performance testing is done at a later stage it can still prove beneficial. For instance, you made certain changes in the code that caused the entire application to crash. In such cases, a rollback can take place where all the changes will be undone and the code will be restored to the previous version. This helps the developers to get an insight into their code and foresee things that may or may not work the way they have planned. With such insights, they can find a solution early and iterate through it without wasting much of the time. Performance testing if integrated with continuous delivery pipeline with right test cases can reap best results and enhance the performance of the application.

Test plan:

Testing is fine but what are the varying test cases that will be used to check the performance? Testing each and every code snippet each time is not practically possible. It is way too time-consuming, expensive and not at all a diligent move. It is quite important that right test cases are created so the essential time is not wasted in testing useless codes. The goal is to create a test case for those parts of the code that are expected to be the troublemakers. As the development proceeds, more test cases can be added accordingly.

Continuous deliverable pipeline:

When software or an application is being built or has already reached the customer the addition of new features and functionality is another task. It is done with the help of continuous deliverable pipeline. The main agenda of a continuous deliverable pipeline is to fasten the process by enabling a constant flow of changes with the help of automation software production line. A pipeline helps to breakdown the software delivery process into various steps or stages. Each step is focused on achieving the right quality of the feature and validating it from all the possible angles. It also aims at providing a code that doesn’t affect the overall performance of the application. The pipeline communicates all the changes to the entire development team. It is made sure that functionality is rolled out only when it is 100% quality fit. Even a slight compromise in the quality of the product can lead to dissatisfied customers and an overall poor system quality. A new functionality cannot be added till the quality is perfectly tight. Testing at different phases with varying scenarios can make this happen. New features and functionalities are kept adding to the central code and simultaneously unit tests and integration tests are performed. Performance testing, on the other hand, is left for the end. Instead, a better approach can be performing performance tests much early instead of waiting for the completion of other processes.

This is the most critical part of the continuous delivery pipeline. All the functionalities and the features should only be added to the final product when the quality standard is hundred percent up to the mark. This can only be gained by proper testing methodologies. When the product is tested again and again and is gone through proper performance testing then only we know that the right goal is hit. Most of the time development teams try to implement a whole big system that becomes a lot more problematic and complex. The quality check factors like robustness, extensibility, and maintainability are brought into focus during the end completion. As the deadline starts to approach the quality is the first thing that is compromised.

When performance tests are integrated into the delivery pipeline the main focus is to catch all the problems before they are put into the final phase of production. It is not possible to test the product in a live production environment so a similar dummy environment can be created and the products can be tested out there. This allows checking the performance of the application in the similar environment.

With continuously deliverable pipeline and proper performance testing the end product is up to the mark error free and as per the quality standards. It may be a bit expensive to do but the truth is that it is way too beneficial in the long run. The reason why performance testing is time-consuming and complex is that we test the important parts again and again. This can be simplified if the performance tests are done parallel with the unit and integration testing. This will not only save you some time but also ease out the complete development process.With continuously deliverable pipeline and proper performance testing the end product is up to the mark error free and as per the quality standards.

Conclusion

Performance testing can be said to be the key to a continuous deliverable pipeline. It ensures delivery of an error-free and high-quality application. The testing phase allows pointing out the problems in early stages which prevent delay and also allows the delivery of an efficient system. The performance testing is often neglected because it incurs a high cost but with proper planning and an efficient implementation, the costs can be optimized. This will lead to a development of the reliable and effective system at a faster pace.
