A system should be optimal in terms of reliability, speed, scalability, robustness, stability, and performance. An application may be delivering the desired results with 100 active users, but will it be equally efficient with 10,000 users? How do you figure this out? Performance testing is the answer. Read on to learn about performance testing and the various performance testing tools.

What is Performance Testing? 

Fortunately, there is a way to measure the exact response and behavior of information systems. It is here when performance testing comes into the picture. Performance testing is a process of testing the application before making it available for the public. The performance testing tools used in this method find the bugs and faults in the application (if there are any). 

Why is Performance Testing Needed?

Through this testing process, you can be assured that an application is capable enough of withstanding the load of requests, data volumes, and concurrent users.

Now before we go through the various performance testing tools, let us first look into the types of performance testing.

What are the Types of Performance Testing?

There are different types of performance testing, each with different uses and purposes. In this article, we have elaborated on the best-rated load testing tools to help you find the right pick for testing the capability of your unique application(s). So, let’s get started.

  • Repeatable and measurable load/performance generation. 
  • Records the test results automatically.

4. The Grinder

It is one of the most popular Java-based, free performance testing tools that require a BSD-style open-source license for use. The brainchild of Paco Gomez, this tool facilitates the users with distributed testing and flexible parameterization. The Grinder can create testing data in no time by using databases, files, and other sources of external data. But most importantly, developers should have a Selenium Certification Training so that they can handle such performance testing solutions expertly.

Core Features 

  • Test script/modification leveraging the power of Java API and Closure/Python combined. 
  • TCP proxy for network activity recording.
  • Offers complete access to end-results for verification/correlation. 

5. AppDynamics 

Counted among the best performance testing tools, AppDynamics helps users to analyze and optimize complex applications. It is suitable for the systems created using GoLang, .Net, PHP, C++, Java, node js, Apache Web Server, or Python. The tool can measure an application’s performance in real-time. With its help, developers can compare user experiences and system performance with their business’s performance to improve it further. 

Core Features 

  • Data retention
  • Powerful alerting and baselining 
  • Highlights performance-related issues during the production process
  • Easy to install and use
  • Database agents
  • Synthetic monitoring
  • Server visibility

6. Gatling

Stephane Landelle developed this open-source, cost-free performance testing solution to benefit the testers with a self-explanatory tool that can develop tests in easy to write and read DSL (domain-specific language). It comes with a powerful Graphical User Interface and HTTP Recorder. At the same time, it is to be noted that courses like Node.js Certification Training can help you use Gatling and other similar performance testing tools optimally.

Core Features  

  • Scale-based
  • Uses non-blocking asynchronous approach for high load production
  • HTTP(S) standardized 
  • Ideal for JMS and JDBC load testing
  • Generates data-driven tests by using different input sources 
  • Powerful assertions system
  • Offers in-depth analysis of load reports

7. NeoLoad

All those who wonder why we need performance testing should try NeoLoad for once to experience the various benefits offered by such platforms. This automated, enterprise-level solution is designed for APIs and application performance testing. The tool will benefit the developers and testers with Automated API testing, user behaviour simulation, and real-time analysis of the issue. 

Core Features 

  • It designs, runs, and maintains performance tests. 
  • Uses plugins for CD and CI tools for real-time analysis of test results.
  • Creates quick test scripts for complex systems with the help of a power-packed graphical user interface.
  • Has dynamic and dedicated testing Infrastructure.

8. Locust

This Open Source, performance testing solution, enables the developers to define the behaviour of the users. It uses Python for running application performance under concurrent users up to millions.
