The software that can’t serve the purpose and eventually contains flaws could be the biggest nightmare for the application developers. Whether it is an issue related to the performance or stability of an application, the testing professional needs to be sure enough that the quality isn’t compromised in any instance!

An unreliable code could be the reason for numerous flaws in your software that can eventually affect the overall performance. When it comes to quality coding and testing services, you need to be sure enough that you prefer a renowned testing professional that can augment your needs.

When it comes to DevOps, one just can’t randomly assure the quality of the software without utilizing the best testing methodologies and test cases. Here we would be sharing adequate details related to the DevOps performance testing that everyone ought to know.

The Initial Testing Phase

In this phase, the performance of the application is tested without any load to set the baseline. This simply means that only a single virtual user is set to perform certain tasks on the loop to check the basic functionality of the application and to analyze the performance without a heavy load.

These baseline tests are necessarily important as they set a response time that the command or the transaction wouldn’t require a lesser time than this baseline. Once the transaction is executed and a proper response is generated, you can enhance the load and monitor the factors associated with the performance of the application. These factors include the adequate utilization of CPU, memory usage, and processing time.

The testing professional needs to note the fastest transaction time and the slowest and then work precisely to minimize the transaction time when the load is maximum. It is the responsibility of the testing professional to maintain the stability of the application in both the scenarios so as to deliver steady performance even in the heavy load scenarios.

Emphasize Finding the Cutoff Points

Another crucial thing that requires adequate consideration is to find the breakpoints by testing a scenario on a loop up to the point where it breaks. It is important to analyze the cutoff point so as to ensure that the transactions need not suffer from the increase in a number of requests at the same time.

There is no point of deploying your application when you can’t assure smooth functioning with the increase in a number of users. Thus, it is mandatory to test the application up to an extent where it reaches the breakpoint so that the load testing and similar practices could be implemented to resolve any glitches.

Once the application is tested for cutoff points, it is time to resolve the issues that are preventing the normal functionality of the application or software.

Repeating the Test Scripts

There is no point at which you can rely on single test scenarios when it comes to the endurance testing of your software program. You have to repeat the test scripts again and again so as to ensure the endurance of the software. Most of the testing professionals prefer an automation testing tool that can do the job.

The automation testing tools like Selenium are designed in a way to augment your software testing practices in a way that harmonizes the monitoring of the app in extreme conditions. It is not feasible to manually test the application when you actually need to put a load of a number of users. Hence the use of the automated script is necessarily important to add virtual users in the testing procedure that can easily depict the overall performance of the system.

The continuous performance testing of your application helps in figuring out the changes to the CPU and memory usage. This again helps the developer to perform certain alterations that can enhance the performance in all aspects.

Tools That are Widely Used for Testing in DevOps Environment

Selenium

One of the most commonly preferred testing tools is Selenium, which can offer the finest testing experience. Whether you need to test the mobile application for overall performance and loopholes or need to check the breakpoint of a web application, you can always rely on Selenium.

Selenium is also widely used for testing desktop applications for enhancing their efficiency. It is always a rewarding decision to prefer a testing tool like Selenium when it comes to the overall performance testing of an application.

UFT

UFT is again a powerful performance testing tool that can lend a hand in monitoring the system’s performance without many efforts. Whether it is the testing of web applications or services, you can use this tool for efficient results. Moreover, this tool also features automated documentation, which is again a plus point.

These are some crucial aspects related to the DevOps performance testing that every developer and testing professional should know.
