Expert’s Guide to Shift from Performance Testing to Performance Engineering


In the recent past, we have witnessed a sudden spike in digital gadgets and the number of updates being rolled out continuously to achieve better user experience. Developers and businesses prioritize the best testing practices and performance testing to detect bugs in code. Now, the new concept of performance engineering has turned the table.

Unlike performance testing, performance engineering focuses on the performance of the mobile application right from the product development stage. It happens by conducting continuous performance assessments and improvement processes.

This blog illustrates the difference between performance testing and performance engineering and how you can shift to performance engineering without any hassle.

Performance Testing Vs Performance Engineering

Before spotting the difference let’s take a dig with some basics.

  • Performance Testing – It is a non-functional testing used to test the quality of the software. The testing operation is carried out after the code part concludes and it examines how the system responds to the workload.
  • Performance Engineering – It is a systematic approach to monitor the performance of the system right from the development stage. This approach reduces the last-minute bug and rework. Performance engineering involves teamwork which provides continuous feedback to ensure the system increases the business value.  

Both performance testing and performance engineering are two sides of the same coin. There is not much difference between them. They both adopt best testing practices to ensure the system delivers the best performance with a better user experience. The only thing that differentiates these two is the timing of performance issue identification.

Performance testing is aimed to test the system’s ability to handle workload along with its responsiveness. So it is carried out right after the coding process is completed. On the other hand, performance engineering is the process of optimizing the system right from its software development life cycle (SDLC) to discover potential issues in an earlier stage.

Why is Performance Engineering Better? Why Should You Shift?

Unlike performance testing, performance engineering is carried out right from SDLC ensuring the system is developed according to the requirements. It creates a collaborative workplace where stakeholders, designers, developers, and testers can view the development process and provide feedback. Performance engineering aims to detect the performance issue right at the early stage of the system development and increase the business value.

Apart from that, here are a few fascinating reasons that will trigger you to shift to performance engineering.

  • Performance eliminates the risk of rework and system refactoring.
  • Cost-effective method of detecting performance issues.
  • Aimed to optimize the end-to-end application performance.
  • Introduces DevOps methodology in SPE.
  • Early detection of the performance issue.
  • Gives insights into other performance metrics like code quality, security, and compatibility.
  • Early detection ensures the system has stable and reliant UX.
  • Promotes businesses to reach the market in a faster time.

Step-by-Step Guide for Moving from Performance Testing to Performance Engineering

It requires a strategic move for a smoother transition from performance testing to performance engineering. Here is the expert’s guidance for moving to performance engineering and achieving better product quality and user experience.  

  1. Access current testing procedures.

As an initial step, you should consider accessing the present performance testing procedures to identify the presence of gaps and flaws. This will give you a clear knowledge of the purpose of testing and whether you need to follow a proactive approach to enhance the system’s performance.

If so, you can prefer doing performance assessment throughout the development lifecycle. Accessing the current testing procedure and tools gives you enough metrics to understand your current stand. Once you are aware of your stand, you can set the objectives for achieving the growth.   

  1. Define performance metrics or goals.

Second, you need to define goals for your system’s performance. It can be monitored based on the performance metrics gathered through the testing procedure. In general, metrics like the system’s response time, scalability, and resource utilization are enough to understand how your system is performing.

Once you are well-defined with your system objectives you can set a clear roadmap for narrating performance engineering efforts. Your goal must match the user’s expectations and ensure the system works at its full potential. Also, you must ensure maintaining a balance between the business goal and user expectations while defining the system’s objective based on metrics.

  1. Develop a scalable strategy.

The ultimate aim of shifting to performance engineering is to reduce the development and testing cost of your system or application. The performance engineering approach also requires a significant budget and resources. So, it’s better to be prepared and develop a robust scalability and budgeting strategy.

This will ensure your organization prepares to handle the increased workload of conducting performance engineering during SDLC. With the collaboration of the right technology, your team will be ready to accommodate the system’s growth and demand fluctuations.

  1. Integrate automation & DevOps practices.

Performance engineering testing is a modern testing approach that requires automation in the testing process. This executes the testing procedures effectively and accurately. At the same time, performance engineering enables collaborative work during the SDLC. Thus, it is mandatory to integrate DevOps and Automation practices with the testing procedure.

This guarantees that the system meets user requirements with a better user experience. 

  1. Use the latest tools & techniques.

Businesses must monitor the performance of their applications in real-time, or else it damages the brand reputation. For testing, you must consider using the latest monitoring tools. This enables companies to address performance bottlenecks proactively.

Companies can perform routine analysis and adjust their strategy based on collected insights through tools. This assures your application performs well and increases your business value.

Bottom Line

Performance engineering becomes one of the integral parts of the SDLC that ensures the delivery of high-quality products. It increases the user experience level of the product by reducing the development and testing costs significantly.

With this modern testing procedure, the SDLC team can easily and quickly detect or prevent performance issues. Switching from the traditional testing process to an advanced testing approach will bring great advantages.
