Performance testing is a type of non-functional software testing that looks at how well an application’s stability, speed, scalability, and responsiveness perform under a certain load. It’s an important step in guaranteeing software quality, but it’s typically seen as an afterthought, to be done after functional testing and, in most cases, after the code is ready to release.

What is Performance Testing?

Performance testing is a type of software testing that ensures that the application is performing well under stressful conditions. The goal of performance testing is to determine the performance bottlenecks and to measure the quality attributes of the system. It helps the performance of the software in terms of speed, response time, scalability, resource usage, and stability under workload conditions. 

What are Performance Testing Tools? 

Performance testing tools help to perform performance testing on the software to check the speed, reliability, response time, resource usage, and other performance metrics under the expected workload. 

  • These tools help to validate the software’s basic features.
  • Helps to identify the issues that need to be fixed before launching the site or app.
  • They also help to detect scalability issues.

Types of Performance Testing

Below are the 6 types of performance testing:

  • Stress Testing: Stress testing is a type of performance testing that determines the robustness of software systems by testing under pressure conditions. 
  • Spike Testing: Spike testing is a type of performance testing that is done by a sudden increase or decrease in load. The goal here is to determine the behavior of the software under extreme variations in traffic.
  • Load Testing: Load testing is a type of performance testing where the system’s behavior is determined under both normal and extreme load conditions. The goal here is to determine the maximum operating capacity of the system and the component that is causing the degradation. 
  • Endurance Testing: Endurance testing is a type of performance testing where the system is tested with a load, extended over a significant period of time to monitor the behavior of the software under sustained use. The goal here is to determine whether the application can resist the processing load it is expected to have to endure for a long period. 
  • Volume Testing: Volume testing is a type of performance testing where the software is subjected to a huge volume of data. The goal here is to check the system performance with an increased volume of data in the database. 
  • Scalability Testing: Scalability testing is a type of performance testing where 

Benefits of Performance Testing

Below are some of the benefits of performance testing:

  • Meet customer expectations: Performance testing helps to meet the desired software features and keep customers happy as no customer will like to use slow laggy software. Performance testing helps to identify performance bottlenecks and thus enhances customer satisfaction. 
  • Improve code quality: Detecting the issues and fixing them early helps to maintain the quality of the code, delivering expected speed, reliability, scalability, and stability. 
  • Enhance software optimization capability: With performance testing, one can optimize the software in such a way that helps the software withstand high numbers of concurrent users. 
  • Identifying issues in the software: siteThis helps to identify the issues that can be corrected before launching the app or site, thus developer can focus on improving the technology instead of resolving the issues after the release. 
  • Measure software’s performance metrics: Performance testing helps to measure the metrics like speed, reliability, scalability, scalability, and other metrics that affect the performance of the software under the workload. Testing and monitoring these factors helps to identify how the application will behave under pressure conditions. 

Factors determine to Consider While Selecting a Performance Testing Tool

The following are some factors that should be considered before selecting a performance testing tool:

  1. License cost and type: Review and be aware of the license of the tool before using it as commercial tools offer better protocol support but with certain restrictions. Check and compare the prices of the paid tool with other tools in the market and select the one that meets your requirements and falls within your budget.
  2. Desired protocol support: Choose a tool based on the nature of the application protocol you would like to utilize as different vendors offer different protocols such as HTTP, HTTPS, etc.
  3. Hardware/ Software requirements of the automation tool: It is important to consider the hardware and software requirements of the automation tool to keep the cost of the software testing within budget.
  4. Languages for writing scripts: It is better to choose a tool that supports many different common languages like Java, and Python for writing the test scripts. Tools that require special skill development before using it may appear less user-friendly in comparison to the tools that use common languages for scripts.
  5. Option to record or playback: The record and playback option helps to run the test cases without programming knowledge. 
  6. Online forums and vendor assistance: Commercial vendors generally offer high-quality support through various channels of communication.
  7. Ease of use: The performance testing tool chosen should be easy enough to use for the testers.
  8. Test environment: The performance testing tool must access enough network and hardware resources. If the selected tool cannot generate a test environment to simulate an expected amount of network traffic then it might not be suitable to meet the company’s requirements.
  9. Tool efficiency: The tool efficiency is more if it needs fewer devices and produces large-scale tests. It must be capable of generating an expected number of virtual users on the current hardware and software setup.
  10. Seamless Integration: The performance testing tools work best when integrated with other tools like defect management. This will help the tester to get an idea of how to track tests and find defects easily.
