Top 5 Performance Testing Tools in 2019
- Katalon Studio
- Apache JMeter
In practice, software applications are often encountered problems such as running slow while several users use it simultaneously, inconsistency across different operating system and poor usability. To address these issues, a method was generated: Performance testing. The main purpose of this testing type is to provide stakeholders with information about the application regarding speed, stability, and scalability.
What is performance testing?
Performance testing is a non-functional testing technique performed to determine the system parameters in terms of responsiveness and stability under various workload. The goal of performance testing is not to find bugs but to eliminate performance bottlenecks such as long load time, poor response time, poor stability, etc.
Performance testing types
As a tester, it is essential to understand various types of test and how those can benefit your applications. Performance testing is generally categorized into common categories below:
- Load testing: This testing type is used to evaluate the performance of the system under normal and peak load conditions.
- Endurance testing: Endurance testing is an evaluation of how software performs with a normal workload over an extended amount of time. The purpose of this testing type is to check for system problems. Endurance testing is also known as soak testing
- Volume testing: also known as Flood testing – is used to determine how efficiently software performs with a large, projected amount of data.
- Scalability testing: This testing type is used to measure the application’s performance in terms of its ability to scale up or scale down the number of user requests or any of its non-functional capability.
- Spike testing: Spike testing is done to estimate the weakness of an application.
- Stress testing: The purpose of this testing is to evaluate the performance of the system when the application is pushed beyond the normal or peak load conditions.
Automation testing tools
Automated tools are used to execute performance testing when you need to simulate real user activities.
They work as follow:
- Identify transactions and pages to test
- Record user activity, a script will be generated
- Identify data and parameters of the application (workload characterization)
- Modify the script according to the data just identified to reflect the activity of several users
- Playback the script increasing the numbers of simulated users (virtual users)
- Extract response time of main user transactions or pages
